MFC of r355574, r358095, and r358395:
Add ACPI battery subsystem man page.
Add _BIX (Battery Information Extended) object support.
ACPI Control Method Batteries have a _BIF and/or _BIX object which provide static properties of the battery. FreeBSD acpi_cmbat module supported _BIF object only, which was deprecated as of ACPI 4.0. _BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and another is in ACPI 6.0 (rev.1). It seems that hardware vendors still stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility. Microsoft requires _BIX rev.0 for Windows machines, so there are some laptop machines with _BIX rev.0 only. In this case, FreeBSD does not recognize the battery information.
After this change, the acpi_cmbat module gets battery information from _BIX or _BIF object and internally uses _BIX rev.1 data structure as the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX] returns an acpi_bi[fx] structure built by using information obtained from a _BIF or a _BIX object found on the system. The revision number field can be used to check which field is available. The acpiconf(8) utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for userland utilities are not changed and the backward-compatible ABIs are provided. This means that older versions of acpiconf(8) can also work with the new kernel. The (union acpi_battery_ioctl_arg) was padded to 256 byte long to avoid another ABI change in the future. A _BIX object with its revision number >1 will be treated as compatible with the rev.1 _BIX format.
Add workaround for models which do not follow the ACPI specification strictly. Extra objects are now simply ignored instead of rejecting everything.

MFC r326956 (by cem): Implement ACPI CPU support when Processor object is not present
By the ACPI standard (ACPI 5 chapter 8.4 Declaring Processors) Processors can be implemented in 2 distinct ways:
* Through a Processor object type (which provides P_BLK) * Through a Device object type
Prior to this change, the FreeBSD driver only supported the former. AMD Epyc / Poweredge systems we are testing both implement the latter only. Add the missing support.
Because P_BLK is not defined in the device object case, C-states entering must be completely controlled via _CST methods rather than P_LVL2/3.
John Baldwin points out that ACPI 6.0 formally deprecates the Processor keyword, so eventually processors will only be enumerated as Device objects. |

353586: Support hot insertion and removal of PCI devices on EC2.
Install ACPI notify handlers on PCI devices with an _EJ0 method. This handler is invoked when devices are added or removed.
- When an ACPI_NOTIFY_DEVICE_CHECK event posts, rescan the parent bus device. Note that strictly speaking we only need to rescan the specified device, but BUS_RESCAN is what is available, so we rescan the entire bus. - When an ACPI_NOTIFY_EJECT_REQUEST event posts, detach the device associated with the ACPI handle, invoke the _EJ0 method, and then delete the device.
Eventually this might be changed to vector notify events to devd in userspace where devctl can be used instead to permit more complex actions such as graceful unmounting of filesystems. |

MFC r348065:
Correct the way remaining battery life is calculated
Previously, if a system had multiple batteries, the remaining life percentage was calculated as the average of each battery's percent remaining. This results in rather incorrect values when you consider the case of the Thinkpad X270 that has a small 3 cell internally battery, and a hot-swappable 9 cell battery that is used first. Battery 0 is at 100%, but battery 1 is at 10%, you do not infact have 55% of your capacity remaining.
The new method calculates the percentage based on remaining capacity out of total capacity, giving a much more accurate reading.

MFC 346063: Don't pre-reserve resources for CPU devices when they are set.
CPUs can use shared (RF_SHAREABLE) resources for the I/O port used for entering and exiting C states. If this I/O port is included in an ACPI system resource device, then this happens to still work, but if the port wasn't part of a system resource device, only the first CPU could allocate the I/O port and use C states since resource_list_reserve() was always allocating the resource from nexus0 without RF_SHAREABLE. By avoiding the reservation, the flags from the bus_alloc_resource() in the CPU driver (which include RF_SHAREABLE) are honored.

MFC r332918, r333222: go deeper for ACPI suspend bounce test
debug.acpi.suspend_bounce sysctl now allows a deeper dive into the sleep abyss. The system will execute the suspend sequence up to the call to AcpiEnterSleepState(). That includes saving processor contexts and parking APs. Then, instead of actually entering the sleep state, the BSP will call resumectx() to emulate the wakeup. The APs should get restarted by the sequence of Init and Startup IPIs that BSP sends to them.
AcpiOsEnterSleep() is used to implement this feature.

MFC 332733: Workaround fixed I/O port resources encoded as I/O port ranges in _CRS.
ACPI I/O port descriptors use _MIN and _MAX fields to specify the set of allowable base (start) addresses for an I/O port resource along with a _LEN field specifying the length. A fixed resource is supposed to be encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to the end of the fixed range. Relocating I/O ranges only make sense in _PRS (possible resource settings), not in _CRS (current resource settings), so if an I/O port range with _MAX set set to the end of the range is present in _CRS, treat it as a fixed I/O port resource starting at _MIN.

MFC r313447: Ensure the idle thread's loop services interrupts in a timely way when using the ACPI C1/mwait sleep method.
Previously, the mwait instruction would return when an interrupt was pending; however, the idle loop did not actually enable interrupts when this occurred. This led to a situation where the idle loop could quickly spin through the C1/mwait sleep method a number of times when an interrupt was pending. (Eventually, the situation corrected itself when something other than an interrupt triggered the idle loop to either enable interrupts or schedule another thread.)

MFC r309400: Fix for endless recursion in the ACPI GPE handler during boot.
When handling a GPE ACPI interrupt object the EcSpaceHandler() function can be called which checks the EC_EVENT_SCI bit and then recurse on the EcGpeQueryHandler() function. If there are multiple GPE events pending the EC_EVENT_SCI bit will be set at the next call to EcSpaceHandler() causing it to recurse again via the EcGpeQueryHandler() function. This leads to a slow never ending recursion during boot which prevents proper system startup, because the EC_EVENT_SCI bit never gets cleared in this scenario.
The behaviour is reproducible with the ALASKA AMI in combination with a newer Skylake based mainboard in the following way:
Enter BIOS and adjust the clock one hour forward. Save and exit the BIOS. System fails to boot due to the above mentioned bug in EcGpeQueryHandler() which was observed recursing multiple times.
This patch adds a simple recursion guard to the EcGpeQueryHandler() function and also also adds logic to detect if new GPE events occurred during the execution of EcGpeQueryHandler() and then loop on this function instead of recursing.

It tears down the NEW_PCIB and hotplug state including destroying resource managers, deleting child devices, and disabling hotplug events. - Add a detach method to the ACPI PCI-PCI bridge driver which calls pcib_detach() and then frees the copy of the _PRT interrupt routing table. - Add a detach method to the PCI-Cardbus bridge driver which frees the PCI bus resources in addition to calling cbb_detach(). - Explicitly clear any pending hotplug events during attach to ensure future events will generate an interrupt. - If a the Command Completed bit is set in the slot status register when the command completion timeout fires, treat it as if the command completed and the completion interrupt was just lost rather than forcing a detach. - Don't wait for a Command Completed notification if Command Completion interrupts are disabled. The spec explicitly says no interrupt is enabled when clearing CCIE, and on my T400 no interrupt is generated when CCIE is changed from cleared to set, either. In addition, the T400 doesn't appear to set the Command Completed bit in the cases where it doesn't generate an interrupt, so don't schedule the timer either. (If the CC bit were always set, one could always set the timer and rely on the logic of treating CC set as a missed interrupt.)

Add an EARLY_AP_STARTUP option to start APs earlier during boot.
Currently, Application Processors (non-boot CPUs) are started by MD code at SI_SUB_CPU, but they are kept waiting in a "pen" until SI_SUB_SMP at which point they are released to run kernel threads. SI_SUB_SMP is one of the last SYSINIT levels, so APs don't enter the scheduler and start running threads until fairly late in the boot.
This change moves SI_SUB_SMP up to just before software interrupt threads are created allowing the APs to start executing kernel threads much sooner (before any devices are probed). This allows several initialization routines that need to perform initialization on all CPUs to now perform that initialization in one step rather than having to defer the AP initialization to a second SYSINIT run at SI_SUB_SMP. It also permits all CPUs to be available for handling interrupts before any devices are probed.
This last feature fixes a problem on with interrupt vector exhaustion. Specifically, in the old model all device interrupts were routed onto the boot CPU during boot. Later after the APs were released at SI_SUB_SMP, interrupts were redistributed across all CPUs.
However, several drivers for multiqueue hardware allocate N interrupts per CPU in the system. In a system with many CPUs, just a few drivers doing this could exhaust the available pool of interrupt vectors on the boot CPU as each driver was allocating N * mp_ncpu vectors on the boot CPU. Now, drivers will allocate interrupts on their desired CPUs during boot meaning that only N interrupts are allocated from the boot CPU instead of N * mp_ncpu.
Some other bits of code can also be simplified as smp_started is now true much earlier and will now always be true for these bits of code. This removes the need to treat the single-CPU boot environment as a special case.
As a transition aid, the new behavior is available under a new kernel option (EARLY_AP_STARTUP). This will allow the option to be turned off if need be during initial testing. I plan to enable this on x86 by default in a followup commit in the next few days and to have all platforms moved over before 11.0. Once the transition is complete, the option will be removed along with the !EARLY_AP_STARTUP code.
These changes have only been tested on x86. Other platform maintainers are encouraged to port their architectures over as well. The main things to check for are any uses of smp_started in MD code that can be simplified and SI_SUB_SMP SYSINITs in MD code that can be removed in the EARLY_AP_STARTUP case (e.g. the interrupt shuffling).

Add a new bus method to fetch device-specific CPU sets.
bus_get_cpus() returns a specified set of CPUs for a device. It accepts an enum for the second parameter that indicates the type of cpuset to request. Currently two valus are supported:
- LOCAL_CPUS (on x86 this returns all the CPUs in the package closest to the device when DEVICE_NUMA is enabled) - INTR_CPUS (like LOCAL_CPUS but only returns 1 SMT thread for each core)
For systems that do not support NUMA (or if it is not enabled in the kernel config), LOCAL_CPUS fails with EINVAL. INTR_CPUS is mapped to 'all_cpus' by default. The idea is that INTR_CPUS should always return a valid set.
Device drivers which want to use per-CPU interrupts should start using INTR_CPUS instead of simply assigning interrupts to all available CPUs. In the future we may wish to add tunables to control the policy of INTR_CPUS (e.g. should it be local-only or global, should it ignore SMT threads or not).
The x86 nexus driver exposes the internal set of interrupt CPUs from the the x86 interrupt code via INTR_CPUS.
The ACPI bus driver and PCI bridge drivers use _PXM to return a suitable LOCAL_CPUS set when _PXM exists and DEVICE_NUMA is enabled. They also and the global INTR_CPUS set from the nexus driver with the per-domain set from _PXM to generate a local INTR_CPUS set for child devices.
Compared to the r298933, this version uses 'struct _cpuset' in <sys/bus.h> instead of 'cpuset_t' to avoid requiring <sys/param.h> (<sys/_cpuset.h> still requires <sys/param.h> for MAXCPU even though <sys/_bitset.h> does not after recent changes).

Native PCI-express HotPlug support.
PCI-express HotPlug support is implemented via bits in the slot registers of the PCI-express capability of the downstream port along with an interrupt that triggers when bits in the slot status register change.
This is implemented for FreeBSD by adding HotPlug support to the PCI-PCI bridge driver which attaches to the virtual PCI-PCI bridges representing downstream ports on HotPlug slots. The PCI-PCI bridge driver registers an interrupt handler to receive HotPlug events. It also uses the slot registers to determine the current HotPlug state and drive an internal HotPlug state machine. For simplicty of implementation, the PCI-PCI bridge device detaches and deletes the child PCI device when a card is removed from a slot and creates and attaches a PCI child device when a card is inserted into the slot.
The PCI-PCI bridge driver provides a bus_child_present which claims that child devices are present on HotPlug-capable slots only when a card is inserted. Rather than requiring a timeout in the RC for config accesses to not-present children, the pcib_read/write_config methods fail all requests when a card is not present (or not yet ready).
These changes include support for various optional HotPlug capabilities such as a power controller, mechanical latch, electro-mechanical interlock, indicators, and an attention button. It also includes support for devices which require waiting for command completion events before initiating a subsequent HotPlug command. However, it has only been tested on ExpressCard systems which support surprise removal and have none of these optional capabilities.
PCI-express HotPlug support is conditional on the PCI_HP option which is enabled by default on arm64, x86, and powerpc.

Add a pcib_attach_child() method to manage adding the child "pci" device.
This allows the PCI-PCI bridge driver to save a reference to the child device in its softc.
Note that this required moving the "pci" device creation out of acpi_pcib_attach(). Instead, acpi_pcib_attach() is renamed to acpi_pcib_fetch_prt() as it's sole action now is to fetch the PCI interrupt routing table.

Queue the CPU-probing task after all acpi_cpu devices are attached.
Eventually with earlier AP startup this code will change to call the startup function synchronously instead of queueing the task. Moving the time we queue the task should be a no-op since taskqueue threads don't start executing tasks until much later, but this reduces the diff with the earlier AP startup patches.

Add a new PCI bus interface method to alloc the ivars (dinfo) for a device.
The ACPI and OFW PCI bus drivers as well as CardBus override this to allocate the larger ivars to hold additional info beyond the stock PCI ivars.
This removes the need to pass the size to functions like pci_add_iov_child() and pci_read_device() simplifying IOV and bus rescanning implementations.
As a result of this and earlier changes, the ACPI PCI bus driver no longer needs its own device_attach and pci_create_iov_child methods but can use the methods in the stock PCI bus driver instead.

Associate device_t objects with ACPI handles via PCI_CHILD_ADDED().
Previously, the ACPI PCI bus driver did a single pass over the devices in the namespace that were a child of a given PCI bus to associate the PCI bus-enumerated device_t devices with the corresponding ACPI handles. However, this meant that handles were only established at runtime for devices found during the initial PCI bus scan.
PCI_IOV adds devices that show up after the initial PCI bus scan, and coming changes to add a bus rescan can also add devices after the initial scan.
This change adds a pci_child_added() callback to the ACPI PCI bus that walks the namespace to find the ACPI handle for each device that is added. Using a callback means that the handle is correctly set for any device no matter how it is added (initial scan, IOV, or a bus rescan).

Convert pci_delete_child() to a bus_child_deleted() method.
Instead of providing a wrapper around device_delete_child() that the PCI bus and child bus drivers must call explicitly, move the bulk of the logic from pci_delete_child() into a bus_child_deleted() method (pci_child_deleted()). This allows PCI devices to be safely deleted via device_delete_child(). - Add a bus_child_deleted method to the ACPI PCI bus which clears the device_t associated with the corresponding ACPI handle in addition to the normal PCI bus cleanup. - Change cardbus_detach_card to call device_delete_children() and move CardBus-specific delete logic into a new cardbus_child_deleted() method. - Use device_delete_child() instead of pci_delete_child() in the SRIOV code. - Add a bus_child_deleted method to the OpenFirmware PCI bus drivers which frees the OpenFirmware device info for each PCI device.

Use uintmax_t (typedef'd to rman_res_t type) for rman ranges.
On some architectures, u_long isn't large enough for resource definitions. Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but type `long' is only 32-bit. This extends rman's resources to uintmax_t. With this change, any resource can feasibly be placed anywhere in physical memory (within the constraints of the driver).
Why uintmax_t and not something machine dependent, or uint64_t? Though it's possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on 32-bit architectures. 64-bit architectures should have plenty of RAM to absorb the increase on resource sizes if and when this occurs, and the number of resources on memory-constrained systems should be sufficiently small as to not pose a drastic overhead. That being said, uintmax_t was chosen for source clarity. If it's specified as uint64_t, all printf()-like calls would either need casts to uintmax_t, or be littered with PRI*64 macros. Casts to uintmax_t aren't horrible, but it would also bake into the API for resource_list_print_type() either a hidden assumption that entries get cast to uintmax_t for printing, or these calls would need the PRI*64 macros. Since source code is meant to be read more often than written, I chose the clearest path of simply using uintmax_t.

Some BIOSes ACPI bytecode needs to take (sleepable) acpi mutex for acpi_GetInteger() execution. Intel DMAR interrupt remapping code needs to know UID of the HPET to properly route the FSB interrupts from the HPET, even when interrupt remapping is disabled, and the code is executed under some non-sleepable mutexes.
Cache HPET UIDs in the device softc at the attach time and provide lock-less method to get UID, use the method from the dmar hpet handling code instead of calling GetInteger().

Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of u_long.
Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

Both jkim and avg have some other patches implementing the mwait functionality; this work is unrelated. Linux does not rely on the ACPI to provide correct tables describing Cx modes. Instead, the driver has pre-defined knowledge of the CPU models, it was supplied by Intel.

This is inspired by something in jhb's NUMA IRQ allocation patchset.
However, the tricky bit here is that the PXM lookup for a node may fail, requiring a lookup on the parent node. So if it doesn't exist, don't fail - just go up to the parent. Only error out of the lookup is the ACPI lookup returns an error.

Implement interface to create SR-IOV Virtual Functions
Implement the interace to create SR-IOV Virtual Functions (VFs). When a driver registers that they support SR-IOV by calling pci_setup_iov(), the SR-IOV code creates a new node in /dev/iov for that device. An ioctl can be invoked on that device to create VFs and have the driver initialize them.

Add a new device control utility for new-bus devices called devctl. This allows the user to request administrative changes to individual devices such as attach or detaching drivers or disabling and re-enabling devices. - Add a new /dev/devctl2 character device which uses ioctls for device requests. The ioctls use a common 'struct devreq' which is somewhat similar to 'struct ifreq'. - The ioctls identify the device to operate on via a string. This string can either by the device's name, or it can be a bus-specific address. (For unattached devices, a bus address is the only way to locate a device.) Bus drivers register an eventhandler to claim unrecognized device names that the driver recognizes as a valid address. Two buses currently support addresses: ACPI recognizes any device in the ACPI namespace via its full path starting with "\" and the PCI bus driver recognizes an address specification of 'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector strings supported by pciconf). - To make it easier to cut and paste, change the PnP location string in the PCI bus driver to output a full PCI selector string rather than 'slot=<slot> function=<func>'. - Add a devctl(3) interface in libdevctl which provides a wrapper around the ioctls and is the preferred interface for other userland code. - Add a devctl(8) program which is a simple wrapper around the requests supported by devctl(3). - Add a device_is_suspended() function to check DF_SUSPENDED. - Add a resource_unset_value() function that can be used to remove a hint from the kernel environment. This is used to clear a hint.<driver>.<unit>.disabled hint when re-enabling a boot-time disabled device.

hook userland threads suspend + resume into acpi suspend code
Also, split power_suspend into power_suspend and power_suspend_early.
power_suspend_early is called before the userland is frozen. power_suspend is called after the userland is frozen.
Currently only VT switching is hooked to power_suspend_early. This is needed because switching away from X server requires its cooperation, so obviously X server must not be frozen when that happens.
Freezing userland during ACPI suspend is useful because not all drivers correctly handle suspension concurrent with other activity. This is especially applicable to drivers ported from other operating systems that suspend all software activity between placing drivers and hardware into suspended state. In particular drm2/radeon (radeonkms) depends on the described procedure. The driver does not have any internal synchronization between suspension activities and processing of userland requests.
Many thanks to kib for the code that allows to freeze and thaw all userland threads.
Note that ideally we also need to park / inhibit (non-special) kernel threads as well to ensure that they do not call into drivers.

Use the correct device (child) when asking the bus layer about which power state said device should go into.
This was a snafu introduced in the ACPI/PCI awareness separation.
When putting a device into a power state, the bus (and thus firmware, eg ACPI) should be asked before hand to check whether the device can indeed go into that power state.
There's a set of nodes in ACPI under each device - the _SxD nodes - which state which ACPI power state to put the device into when the system is going into power save state 'x'. So when going into S3, the existence of an _S3D node would override whatever the system was trying to do.
By default the PCI code wants to put devices into D3 before suspending.
I have a laptop here (Asus Zenbook - check the PR) whose EHCI controller really wants to be in D2 during suspend, not D3. So if we put it into D3 and then try to enter S3, everything hangs. The device itself can go into D3 - it just can't be there when the call to ACPI to enter S3 occurs. The PCI patch fixes this.
jkim@ noticed that the same is needed for the ACPI child device enumeration.
Thankyou to Matt Dillon (the programmer, not the actor) for buying me this particular laptop so I could debug the issues with the Atheros AR9485 that is in it. It's his fault that I ended up with this laptop and was sufficiently annoyed by the lack of USB suspend to go down this rabbit hole.

HPET: create /dev/hpetN as a way to access HPET from userland.
In some cases, TSC is broken and special applications might benefit from memory mapping HPET and reading the registers to count time. Most often the main HPET counter is 32-bit only[1], so this only gives the application a 300 second window based on the default HPET interval. Other applications, such as Intel's DPDK, expect /dev/hpet to be present and use it to count time as well.
Although we have an almost userland version of gettimeofday() which uses rdtsc in userland, it's not always possible to use it, depending on how broken the multi-socket hardware is.
Install the acpi_hpet.h so that applications can use the HPET register definitions.
[1] I haven't found a system where HPET's main counter uses more than 32 bit. There seems to be a discrepancy in the Intel documentation (claiming it's a 64-bit counter) and the actual implementation (a 32-bit counter in a 64-bit memory area).

This patch adds support for MSI interrupts when running on Xen. Apart from adding the Xen related code needed in order to register MSI interrupts this patch also makes the msi_init function a hook in init_ops, so different MSI implementations can have different initialization functions.
Sponsored by: Citrix Systems R&D
xen/interface/physdev.h: - Add the MAP_PIRQ_TYPE_MULTI_MSI to map multi-vector MSI to the Xen public interface.
x86/include/init.h: - Add a hook for setting custom msi_init methods.
amd64/amd64/machdep.c: i386/i386/machdep.c: - Set the default msi_init hook to point to the native MSI initialization method.
x86/xen/pv.c: - Set the Xen MSI init hook when running as a Xen guest.
x86/x86/local_apic.c: - Call the msi_init hook instead of directly calling msi_init.
xen/xen_intr.h: x86/xen/xen_intr.c: - Introduce support for registering/releasing MSI interrupts with Xen. - The MSI interrupts will use the same PIC as the IO APIC interrupts.
xen/xen_msi.h: x86/xen/xen_msi.c: - Introduce a Xen MSI implementation.
x86/xen/xen_nexus.c: - Overwrite the default MSI hooks in the Xen Nexus to use the Xen MSI implementation.
x86/xen/xen_pci.c: - Introduce a Xen specific PCI bus that inherits from the ACPI PCI bus and overwrites the native MSI methods. - This is needed because when running under Xen the MSI messages used to configure MSI interrupts on PCI devices are written by Xen itself.
dev/acpica/acpi_pci.c: - Lower the quality of the ACPI PCI bus so the newly introduced Xen PCI bus can take over when needed.
conf/files.i386: conf/files.amd64: - Add the newly created files to the build process.

Create a separate structure for per-CPU state saved across suspend and resume that is a superset of a pcb. Move the FPU state out of the pcb and into this new structure. As part of this, move the FPU resume code on amd64 into a C function. This allows resumectx() to still operate only on a pcb and more closely mirrors the i386 code.

Extend the meaning of the CTLFLAG_TUN flag to automatically check if there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel.
Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

Trust the state of a power resource that get from a working _STA method instead of trying to cache it.
Previously, we only trusted the state if we did not have a cached state. However, once a state was cached, the _STA method was always ignored. Specifically, once a power resource had been turned on once (e.g. during resume), the driver assumed it was always on even if _STA said it was off and never turned it back on. This prevented the power resource from being turned back on if a laptop was resumed twice, for example.
To fix, just remove the cached state entirely and always use the results of _STA. The loops already skip any resources where _STA fails.

For now this'll match up with the "wakeups"; although I'll dig deeper into this to see if we can determine which sleep state the CPU managed to get into. Most things I've seen these days only expose up to C2 or C3 via ACPI even though the CPU goes all the way down to C6 or C7.

Add support for managing PCI bus numbers. As with BARs and PCI-PCI bridge I/O windows, the default is to preserve the firmware-assigned resources. PCI bus numbers are only managed if NEW_PCIB is enabled and the architecture defines a PCI_RES_BUS resource type. - Add a helper API to create top-level PCI bus resource managers for each PCI domain/segment. Host-PCI bridge drivers use this API to allocate bus numbers from their associated domain. - Change the PCI bus and CardBus drivers to allocate a bus resource for their bus number from the parent PCI bridge device. - Change the PCI-PCI and PCI-CardBus bridge drivers to allocate the full range of bus numbers from secbus to subbus from their parent bridge. The drivers also always program their primary bus register. The bridge drivers also support growing their bus range by extending the bus resource and updating subbus to match the larger range. - Add support for managing PCI bus resources to the Host-PCI bridge drivers used for amd64 and i386 (acpi_pcib, mptable_pcib, legacy_pcib, and qpi_pcib). - Define a PCI_RES_BUS resource type for amd64 and i386.

Some BIOSes incorrectly use standard memory resource ranges to list the memory ranges that they decode for downstream devices rather than creating ResourceProducer range resource entries. The result is that we allocate the full range to the PCI root bridge device causing allocations in child devices to all fail.
As a workaround, ignore any standard memory resources on a PCI root bridge device. It is normal for a PCI root bridge to allocate an I/O resource for the I/O ports used for PCI config access, but I have not seen any PCI root bridges that legitimately allocate a memory resource.

Import the driver for VT-d DMAR hardware, as specified in the revision 1.3 of Intelб╝ Virtualization Technology for Directed I/O Architecture Specification. The Extended Context and PASIDs from the rev. 2.2 are not supported, but I am not aware of any released hardware which implements them. Code does not use queued invalidation, see comments for the reason, and does not provide interrupt remapping services.
Code implements the management of the guest address space per domain and allows to establish and tear down arbitrary mappings, but not partial unmapping. The superpages are created as needed, but not promoted. Faults are recorded, fault records could be obtained programmatically, and printed on the console.
Implement the busdma(9) using DMARs. This busdma backend avoids bouncing and provides security against misbehaving hardware and driver bad programming, preventing leaks and corruption of the memory by wild DMA accesses.
By default, the implementation is compiled into amd64 GENERIC kernel but disabled; to enable, set hw.dmar.enable=1 loader tunable. Code is written to work on i386, but testing there was low priority, and driver is not enabled in GENERIC. Even with the DMAR turned on, individual devices could be directed to use the bounce busdma with the hw.busdma.pci<domain>:<bus>:<device>:<function>.bounce=1 tunable. If DMARs are capable of the pass-through translations, it is used, otherwise, an identity-mapping page table is constructed.
The driver was tested on Xeon 5400/5500 chipset legacy machine, Haswell desktop and E5 SandyBridge dual-socket boxes, with ahci(4), ata(4), bce(4), ehci(4), mfi(4), uhci(4), xhci(4) devices. It also works with em(4) and igb(4), but there some fixes are needed for drivers, which are not committed yet. Intel GPUs do not work with DMAR (yet).
Many thanks to John Baldwin, who explained me the newbus integration; Peter Holm, who did all testing and helped me to discover and understand several incredible bugs; and to Jim Harris for the access to the EDS and BWG and for listening when I have to explain my findings to somebody.

Don't perform the acpi_DeviceIsPresent() check for PCI-PCI bridges. If we are probing a PCI-PCI bridge it is because we found one by enumerating the devices on a PCI bus, so the bridge is definitely present. A few BIOSes report incorrect status (_STA) for some bridges that claimed they were not present when in fact they were.
While here, move this check earlier for Host-PCI bridges so attach fails before doing any work that needs to be torn down.

When checking to see if a video output's _ADR matches an entry in the parent adapter's _DOD list, only check the low 16 bits of both _ADR and _DOD. The language in the ACPI spec seems to indicate that the _ADR values should exactly match the entries in _DOD. However, I assume that the masking added to _DOD values was added to work around some known busted machines (the commit history doesn't indicate either way), and the ACPI spec does require that the low 16 bits are unique for all video outputs, so only check the low 16 bits should be fine.
This fixes recognition of video outputs that use the new standardized device ID scheme in ACPI 3.0 that set bit 31 such as certain Dell laptops.

Add several performance optimizations to acpi_cpu_idle().
For C1 and C2 states use cpu_ticks() to measure sleep time instead of much slower ACPI timer. We can't do it for C3, as TSC may stop there. But it is less important there as wake up latency is high any way.
For C1 and C2 states do not check/clear bus mastering activity status, as it is important only for C3. As side effect it can make CPU enter C2 instead of C3 if last BM activity was two sleeps back (unlike one before), but that may be even good because of collecting more statistics. Premature BM wakeup from C3, entered because of overestimation, can easily be worse then entering C2 from both performance and power consumption points of view.
Together on dual Xeon E5645 system on sequential 512 bytes read test this change makes cpu_idle_acpi() as fast as simplest cpu_idle_hlt() and only few percents slower then cpu_idle_mwait(), while deeper states are still actively used during idle periods.
To help with diagnostics, add C-state type into dev.cpu.X.cx_supported.

acpi_cpu: separate a notion of current deepest allowed+available Cx level
... from a user-set persistent limit on the said level. Allow to set the user-imposed limit below current deepest available level as the available levels may be dynamically changed by ACPI platform in both directions. Allow "Cmax" as an input value for cx_lowest sysctls to mean that there is not limit and OS can use all available C-states. Retire global cpu_cx_count as it no longer serves any meaningful purpose.

Cosmetic display change of Cx states via cx_supported sysctl entries.
Adjust power_profile script to handle the new world order as well.
Some vendors are opting out of a C2 state and only defining C1 & C3. This leads the acpi_cpu display to indicate that the machine supports C1 & C2 which is caused by the (mis)use of the index of the cx_state array as the ACPI_STATE_CX value.
e.g. the code was pretending that cx_state[i] would always convert to i by subtracting 1.
cx_state[2] == ACPI_STATE_C3 cx_state[1] == ACPI_STATE_C2 cx_state[0] == ACPI_STATE_C1
however, on certain machines this would lead to cx_state[1] == ACPI_STATE_C3 cx_state[0] == ACPI_STATE_C1
This didn't break anything but led to a display of: * dev.cpu.0.cx_supported: C1/1 C2/96

Complete commit message for r235024:
Use MADT to match ACPI Processor objects to CPUs. MADT and DSDT/SSDTs may list CPUs in different orders, especially for disabled logical cores. Now we match ACPI IDs from the MADT with Processor objects, strictly order CPUs accordingly, and ignore disabled cores. This prevents us from executing methods for other CPUs, e. g., _PSS for disabled logical core, which may not exist. Unfortunately, it is known that there are a few systems with buggy BIOSes that do not have unique ACPI IDs for MADT and Processor objects. To work around these problems, 'debug.acpi.cpu_unordered' tunable is added. Set this to a non-zero value to restore the old behavior. Many thanks to jhb for pointing me to the right direction and the manual page change.

Use a more proper fix for enabling HT MSI mapping windows on Host-PCI bridges. Rather than blindly enabling the windows on all of them, only enable the window when an MSI interrupt is enabled for a device behind the bridge, similar to what already happens for HT PCI-PCI bridges.
To implement this, each x86 Host-PCI bridge driver has to be able to locate it's actual backing device on bus 0. For ACPI, use the _ADR method to find the slot and function of the device. For the non-ACPI case, the legacy(4) driver already scans bus 0 looking for Host-PCI bridge devices. Now it saves the slot and function of each bridge that it finds as ivars that the Host-PCI bridge driver can then use in its pcib_map_msi() method.
This fixes machines where non-MSI interrupts were broken by the previous round of HT MSI changes.

- Add a bus_dma tag to each PCI bus that is a child of a Host-PCI bridge. The tag enforces a single restriction that all DMA transactions must not cross a 4GB boundary. Note that while this restriction technically only applies to PCI-express, this change applies it to all PCI devices as it is simpler to implement that way and errs on the side of caution. - Add a softc structure for PCI bus devices to hold the bus_dma tag and a new pci_attach_common() routine that performs actions common to the attach phase of all PCI bus drivers. Right now this only consists of a bootverbose printf and the allocate of a bus_dma tag if necessary. - Adjust all PCI bus drivers to allocate a PCI bus softc and to call pci_attach_common() from their attach routines.

Further relax the strictness of enforcing allocations to only come from decoded ranges. Pass any request for a specific range that fails because it is not in a decoded range for an ACPI Host-PCI bridge up to the parent to see if it can still be allocated. This is based on the assumption that many BIOSes are inconsistent/broken and that settings programmed into BARs or resources assigned to other built-in components are more trustworthy than the list of decoded resource ranges in _CRS. This effectively limits the decoded ranges to only being used for "wildcard" ranges when allocating fresh resources for a BAR, etc. At some point I would like to only be this permissive during an early scan of firmware-assigned resources during boot and to be strict about all later allocations, but that isn't viable currently.

Previous optimization attempt doing it only for intervals less then 5000 ticks (~300us) reported to be unreliable by some people. Probably because of some heavy SMI code on their boards.

Respect the BIOS/firmware's notion of acceptable address ranges for PCI resource allocation on x86 platforms: - Add a new helper API that Host-PCI bridge drivers can use to restrict resource allocation requests to a set of address ranges for different resource types. - For the ACPI Host-PCI bridge driver, use Producer address range resources in _CRS to enumerate valid address ranges for a given Host-PCI bridge. This can be disabled by including "hostres" in the debug.acpi.disabled tunable. - For the MPTable Host-PCI bridge driver, use entries in the extended MPTable to determine the valid address ranges for a given Host-PCI bridge. This required adding code to parse extended table entries.
Similar to the new PCI-PCI bridge driver, these changes are only enabled if the NEW_PCIB kernel option is enabled (which is enabled by default on amd64 and i386).

Add a helper routine to conditionally modify the start address of a resource allocation from an x86 Host-PCI bridge driver so that it can be reused by the ACPI Host-PCI bridge driver (and eventually the MPTable Host-PCI bridge driver) instead of duplicating the same logic. Note that this means that hw.acpi.host_mem_start is now replaced with the hw.pci.host_mem_start tunable that was already used in the non-ACPI case. This also removes hw.acpi.host_mem_start on ia64 where it was not applicable (the implementation was very x86-specific).
While here, adjust the logic to apply the new start address on any "wildcard" allocation even if that allocation comes from a subset of the allowable address range.

Don't create a device_t object or parse current resources (via _CRS) for ACPI Device() objects that do not have any device IDs available via the _HID or _CID methods. Without a device ID a device driver cannot attach to the device anyway. Namespace objects that are devices but not of type ACPI_TYPE_DEVICE are not affected.
A few BIOSes have also attached a _CRS method to a PCI device to allocate resources that are not managed via a BAR. With the previous code those resources are allocated from acpi0 directly which can interfere with the new PCI-PCI bridge driver (since the PCI device in question may be behind a bridge and its resources should be allocated from that bridge's windows instead). The resources were also orphaned and and would end up associated with some other random device whose device_t reused the pointer of the original ACPI-enumerated device (after it was free'd by the ACPI PCI bus driver) in devinfo output which was confusing. If we want to handle _CRS on PCI devices we can adjust the ACPI PCI bus driver to do that in the future and associate the resources with the proper device object respecting PCI-PCI bridges, etc.
Note that with this change the ACPI PCI bus driver no longer has to delete ACPI-enumerated device_t devices that mirror PCI devices since they should in general not exist. There are rare cases when a BIOS will give a PCI device a _HID (e.g. I've seen a PCI-ISA bridge given a _HID for a system resource device). In that case we leave both the ACPI and PCI-enumerated device_t objects around just as in the previous code.

Reimplement how PCI-PCI bridges manage their I/O windows. Previously the driver would verify that requests for child devices were confined to any existing I/O windows, but the driver relied on the firmware to initialize the windows and would never grow the windows for new requests. Now the driver actively manages the I/O windows.
This is implemented by allocating a bus resource for each I/O window from the parent PCI bus and suballocating that resource to child devices. The suballocations are managed by creating an rman for each I/O window. The suballocated resources are mapped by passing the bus_activate_resource() call up to the parent PCI bus. Windows are grown when needed by using bus_adjust_resource() to adjust the resource allocated from the parent PCI bus. If the adjust request succeeds, the window is adjusted and the suballocation request for the child device is retried.
When growing a window, the rman_first_free_region() and rman_last_free_region() routines are used to determine if the front or end of the existing I/O window is free. From using that, the smallest ranges that need to be added to either the front or back of the window are computed. The driver will first try to grow the window in whichever direction requires the smallest growth first followed by the other direction if that fails.
Subtractive bridges will first attempt to satisfy requests for child resources from I/O windows (including attempts to grow the windows). If that fails, the request is passed up to the parent PCI bus directly however.
The PCI-PCI bridge driver will try to use firmware-assigned ranges for child BARs first and only allocate a "fresh" range if that specific range cannot be accommodated in the I/O window. This allows systems where the firmware assigns resources during boot but later wipes the I/O windows (some ACPI BIOSen are known to do this) to "rediscover" the original I/O window ranges.
The ACPI Host-PCI bridge driver has been adjusted to correctly honor hw.acpi.host_mem_start and the I/O port equivalent when a PCI-PCI bridge makes a wildcard request for an I/O window range.
The new PCI-PCI bridge driver is only enabled if the NEW_PCIB kernel option is enabled. This is a transition aide to allow platforms that do not yet support bus_activate_resource() and bus_adjust_resource() in their Host-PCI bridge drivers (and possibly other drivers as needed) to use the old driver for now. Once all platforms support the new driver, the kernel option and old driver will be removed.

Use atomic load & store for TSC frequency. It may be overkill for amd64 but safer for i386 because it can be easily over 4 GHz now. More worse, it can be easily changed by user with 'machdep.tsc_freq' tunable (directly) or cpufreq(4) (indirectly). Note it is intentionally not used in performance critical paths to avoid performance regression (but we should, in theory). Alternatively, we may add "virtual TSC" with lower frequency if maximum frequency overflows 32 bits (and ignore possible incoherency as we do now).

Stop lying about supporting cpu_est_clockrate() when TSC is invariant. This function always returned the nominal frequency instead of current frequency because we use RDTSC instruction to calculate difference in CPU ticks, which is supposedly constant for the case. Now we support cpu_get_nominal_mhz() for the case, instead. Note it should be just enough for most usage cases because cpu_est_clockrate() is often times abused to find maximum frequency of the processor.

There has been no need to do that starting with ACPICA 20040427 as AcpiEnableSubsystem() installs the handlers automatically.

If a state is not supported it should not be included into the return package. In other words, any latency value returned by _CST is valid, it's up to the OS and/or user to decide whether to use it.

Refactor timer management code with priority to one-shot operation mode. The main goal of this is to generate timer interrupts only when there is some work to do. When CPU is busy interrupts are generating at full rate of hz + stathz to fullfill scheduler and timekeeping requirements. But when CPU is idle, only minimum set of interrupts (down to 8 interrupts per second per CPU now), needed to handle scheduled callouts is executed. This allows significantly increase idle CPU sleep time, increasing effect of static power-saving technologies. Also it should reduce host CPU load on virtualized systems, when guest system is idle.
There is set of tunables, also available as writable sysctls, allowing to control wanted event timer subsystem behavior: kern.eventtimer.timer - allows to choose event timer hardware to use. On x86 there is up to 4 different kinds of timers. Depending on whether chosen timer is per-CPU, behavior of other options slightly differs. kern.eventtimer.periodic - allows to choose periodic and one-shot operation mode. In periodic mode, current timer hardware taken as the only source of time for time events. This mode is quite alike to previous kernel behavior. One-shot mode instead uses currently selected time counter hardware to schedule all needed events one by one and program timer to generate interrupt exactly in specified time. Default value depends of chosen timer capabilities, but one-shot mode is preferred, until other is forced by user or hardware. kern.eventtimer.singlemul - in periodic mode specifies how much times higher timer frequency should be, to not strictly alias hardclock() and statclock() events. Default values are 2 and 4, but could be reduced to 1 if extra interrupts are unwanted. kern.eventtimer.idletick - makes each CPU to receive every timer interrupt independently of whether they busy or not. By default this options is disabled. If chosen timer is per-CPU and runs in periodic mode, this option has no effect - all interrupts are generating.
As soon as this patch modifies cpu_idle() on some platforms, I have also refactored one on x86. Now it makes use of MONITOR/MWAIT instrunctions (if supported) under high sleep/wakeup rate, as fast alternative to other methods. It allows SMP scheduler to wake up sleeping CPUs much faster without using IPI, significantly increasing performance on some highly task-switching loads.

Several improvements to HPET driver: - Add special check for case when time expires before being programmed. This fixes interrupt loss and respectively timer death on attempt to program very short interval. Increase minimal supported period to more realistic value. - Add support for hint.hpet.X.allowed_irqs tunable, allowing manually specify which interrupts driver allowed to use. Unluckily, many BIOSes program wrong allowed interrupts mask, so driver tries to stay on safe side by not using unshareable ISA IRQs. This option gives control over this limitation, allowing more per-CPU timers to be provided, when FSB interrupts are not supported. Value of this tunable is bitmask. - Do not use regular interrupts on virtual machines. QEMU and VirtualBox do not support them properly, that may cause problems. Stay safe by default. Same time both QEMU and VirtualBox work fine in legacy_route mode. VirtualBox also works fine if manually specify allowed ISA IRQs with above.

Implement new event timers infrastructure. It provides unified APIs for writing event timer drivers, for choosing best possible drivers by machine independent code and for operating them to supply kernel with hardclock(), statclock() and profclock() events in unified fashion on various hardware.
Infrastructure provides support for both per-CPU (independent for every CPU core) and global timers in periodic and one-shot modes. MI management code at this moment uses only periodic mode, but one-shot mode use planned for later, as part of tickless kernel project.
For this moment infrastructure used on i386 and amd64 architectures. Other archs are welcome to follow, while their current operation should not be affected.
This patch updates existing drivers (i8254, RTC and LAPIC) for the new order, and adds event timers support into the HPET driver. These drivers have different capabilities: LAPIC - per-CPU timer, supports periodic and one-shot operation, may freeze in C3 state, calibrated on first use, so may be not exactly precise. HPET - depending on hardware can work as per-CPU or global, supports periodic and one-shot operation, usually provides several event timers. i8254 - global, limited to periodic mode, because same hardware used also as time counter. RTC - global, supports only periodic mode, set of frequencies in Hz limited by powers of 2.
Depending on hardware capabilities, drivers preferred in following orders, either LAPIC, HPETs, i8254, RTC or HPETs, LAPIC, i8254, RTC. User may explicitly specify wanted timers via loader tunables or sysctls: kern.eventtimer.timer1 and kern.eventtimer.timer2. If requested driver is unavailable or unoperational, system will try to replace it. If no more timers available or "NONE" specified for second, system will operate using only one timer, multiplying it's frequency by few times and uing respective dividers to honor hz, stathz and profhz values, set during initial setup.

While we indeed can't precisely measure time spent in C1, we can consider measured interval as upper bound. It should be more precise then just assuming hz/2. For idle CPU it should be quite precise, for busy - not worse then before.

When updating individual CPU's lowest Cx state to use, never set it to a state lower than the lowest one supported by the current CPU. This closes some races with changes to the hw.acpi.cpu_cx_lowest sysctl while Cx states for individual CPUs were changing (e.g. unplugging the AC adapter of a laptop) that could result in panics.

acpi cpu: probe+attach before all other enumerated children on acpi bus
Some current systems dynamically load SSDT(s) when _PDC/_OSC method of Processor is evaluated. Other devices in ACPI namespace may access objects defined in the dynamic SSDT. Drivers for such devices might have to have a rather high priority, because of other dependencies. Good example is acpi_ec driver for EC. Thus we attach to Processors as early as possible to load the SSDTs before any other drivers may try to evaluate control methods. It also seems to be a natural order for a processor in a device hierarchy.
On the other hand, some child devices on acpi cpu bus need to access other system resources like PCI configuration space of chipset devices, so they need to be probed and attached rather late. For this reason we probe and attach the cpu bus at SI_SUB_CONFIGURE:SI_ORDER_MIDDLE SYSINIT level. In the future this could be done more elegantly via multipass.
Please note that acpi drivers that might access ACPI namespace from device_identify will do that before _PDC/_OSC of Processors are evaluated.
Legacy cpu driver is not affected by this change.

acpi_cpu: prefer _OSC over _PDC, just in case
_PDC was deprecated in favor of _OSC long time ago, but it seems that they still peacefully coexist and in some case only _PDC is present. Still _OSC provides a reacher interface and is capable to report back its status. If the status is non-zero, then report it, we may find it useful to understand what firmware expects from OS. Also clean up some comments that became less useful over time.

Many BIOSes do not include the starting port of the floppy controller listed in the hints (0x3f0) in the resources for the device. So far, however, all the BIOS variations encountered do include the 'port + 2' resource (0x3f2), so adjust the matching for "fdc" devices to look for 'port + 2'.

Make the newbus subsystem Giant free by adding the new newbus sxlock. The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped.
For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens.
Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

Rework the _BBN handling for Host-PCI bridges. Previously we only trusted a _BBN value of 0 if it was for the first bridge encountered since some older systems returned _BBN of 0 for all bridges. However, some newer systems enumerate bridges with non-zero _BBN before bus 0 which is perfectly valid. Handle both cases by trusting the first bridge that has a _BBN of 0 and falling back to reading from non-standard config registers only for subsequent bridges with a _BBN of 0. We also only perform this check for segment (domain) 0. We assume that _BBN is always correct for segments other than 0.

General sleep state change clean up.
- Probe supported sleep states from acpi_attach() just once and do not call AcpiGetSleepTypeData() again. It is redundant because AcpiEnterSleepStatePrep() does it any way. - Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions. - Do not set unsupported sleep states as default button/switch events. If the default sleep state is not supported, just set it as UNKNOWN/NONE. - Do not allow sleep state change if the system is not fully up and running. This should prevent entering S5 state multiple times, which causes strange behaviours later. - Make sleep states case-insensitive when they are used with sysctl(8). For example,
sysctl hw.acpi.lid_switch_state=s1 sysctl hw.acpi.sleep_button_state=none
are now legal and equivalent to the uppercase ones.

acpi: do not run resume/backout code when entering S0/S5 states
This change adds (possibly redundant) early check for invalid state input parameter (including S0). Handling of S5 request is reduced to simply calling shutdown_nice(). As a result control flow of acpi_EnterSleepState is somewhat simplified and resume/backout half of the function is not executed for S5 (soft poweroff) request and invalid state requests.
Note: it seems that shutdown_nice may act as nop when initproc is already initialized (to grab pid of 1), but init process is in "pre-natal" state.

This is triggered only if BIOS configures ACPI_BITREG_BUS_MASTER_RLD aka BRLD_EN_BM to 1. Rationale: 1. we do not support C3 on PIIX4E 2. bus master activity need not break out of C2 state 3. because of CPU_QUIRK_NO_BM_CTRL quirk we may reset bus master status which would result in immediate break out from C2
So if you have seen cpu0: too many short sleeps, backing off to C1 with this chipset before you may want to try cx_lowest of C2 again.

Allow device hints to wire the unit numbers of devices. - An "at" hint now reserves a device name. - A new BUS_HINT_DEVICE_UNIT method is added to the bus interface. When determining the unit number of a device, this method is invoked to let the bus driver specify the unit of a device given a specific devclass. This is the only way a device can be given a name reserved via an "at" hint. - Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers. Both of these busses implement this by comparing the resources for a given hint device with the resources enumerated by ACPI/PnPBIOS and wire a unit if the hint resources are a subset of the "real" resources. - Use bus_hinted_children() for adding hinted devices on isa(4) busses now instead of doing it by hand. - Remove the unit kludging from sio(4) as it is no longer necessary.

Extend the support for PCI-e memory mapped configuration space access: - Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the rest of the kernel. It now also accepts parameters via function arguments rather than global variables. - Add a notion of minimum and maximum bus numbers and reject requests for an out of range bus. - Add more range checks on slot/func/reg/bytes parameters to the cfg reg read/write routines. Don't panic on any invalid parameters, just fail the request (writes do nothing, reads return -1). This matches the behavior of the other cfg mechanisms. - Port the memory mapped configuration space access to amd64. On amd64 we simply use the direct map (via pmap_mapdev()) for the memory mapped window. - During acpi_attach() just after loading the ACPI tables, check for a MCFG table. If it exists, call pciereg_cfgopen() on each subtable (memory mapped window). For now we only support windows for domain 0 that start with bus 0. This removes the need for more chipset-specific quirks in the MD code. - Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets since these machines should all have MCFG tables via ACPI. - Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen() earlier.

Rework how the nexus(4) device works on x86 to better handle the idea of different "platforms" on x86 machines. The existing code already handles having two platforms: ACPI and legacy. However, the existing approach was rather hardcoded and difficult to extend. These changes take the approach that each x86 hardware platform should provide its own nexus(4) driver (it can inherit most of its behavior from the default legacy nexus(4) driver) which is responsible for probing for the platform and performing appropriate platform-specific setup during attach (such as adding a platform-specific bus device). This does mean changing the x86 platform busses to no longer use an identify routine for probing, but to move that logic into their matching nexus(4) driver instead. - Make the default nexus(4) driver in nexus.c on i386 and amd64 handle the legacy platform. It's probe routine now returns BUS_PROBE_GENERIC so it can be overriden. - Expose a nexus_init_resources() routine which initializes the various resource managers so that subclassed nexus(4) drivers can invoke it from their attach routine. - The legacy nexus(4) driver explicitly adds a legacy0 device in its attach routine. - The ACPI driver no longer contains an new-bus identify method. Instead it exposes a public function (acpi_identify()) which is a probe routine that the MD nexus(4) drivers can use to probe for ACPI. All of the probe logic in acpi_probe() is now moved into acpi_identify() and acpi_probe() is just a stub. - On i386 and amd64, an ACPI-specific nexus(4) driver checks for ACPI via acpi_identify() and claims the nexus0 device if the probe succeeds. It then explicitly adds an acpi0 device in its attach routine. - The legacy(4) driver no longer knows anything about the acpi0 device. - On ia64 if acpi_identify() fails you basically end up with no devices. This matches the previous behavior where the old acpi_identify() would fail to add an acpi0 device again leaving you with no devices.

Probe CPUs after the PCI hierarchy on i386, amd64, and ia64. This allows the cpufreq drivers to reliably use properties of PCI devices for quirks, etc. - For the legacy drivers, add CPU devices via an identify routine in the CPU driver itself rather than in the legacy driver's attach routine. - Add CPU devices after Host-PCI bridges in the acpi bus driver. - Change the ichss(4) driver to use pci_find_bsf() to locate the ICH and check its device ID rather than having a bogus PCI attachment that only checked for the ID in probe and always failed. As a side effect, you can now kldload ichss after boot. - Fix the ichss(4) driver to use the correct device_t for the ICH (and not for ichss0) when doing PCI config space operations to enable SpeedStep.

Fix GPE livelock that occurs on HP/Compaq laptops, mostly in the thermal zone code. The GPE handler method (i.e. _L00) generates various Notify events that need to be run to completion before the GPE is re-enabled. In ACPI-CA, we queue an asynch callback at the same priority as a Notify so that it will only run after all Notify handlers have completed. The callback re-enables the GPE afterwards. We also changed the priority of Notifies to be the same as GPEs, given the possibility that another GPE could arrive before the Notifies have completed and we don't want it to get queued ahead of the rest.
The ACPI-CA change was submitted by Alexey Starikovskiy (SUSE) and will appear in a later release. Special thanks to him for helping track this bug down.

Make the PCI code aware of PCI domains (aka PCI segments) so we can support machines having multiple independently numbered PCI domains and don't support reenumeration without ambiguity amongst the devices as seen by the OS and represented by PCI location strings. This includes introducing a function pci_find_dbsf(9) which works like pci_find_bsf(9) but additionally takes a domain number argument and limiting pci_find_bsf(9) to only search devices in domain 0 (the only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order to no longer report false positives when searching for siblings and dupe devices in the same domain respectively. Along with this change the sole host-PCI bridge driver converted to actually make use of PCI domain support is uninorth(4), the others continue to use domain 0 only for now and need to be converted as appropriate later on. Note that this means that the format of the location strings as used by pciconf(8) has been changed and that consumers of <sys/pciio.h> potentially need to be recompiled.

Rewrite the EC driver event model. The main goal is to avoid polling/interrupt-driven fallback and instead use polling only during boot and pure interrupt-driven mode after boot. Polled mode could be relegated completely to a legacy role if we could enable interrupts during boot. Polled mode can be forced after boot by setting debug.acpi.ec.polled="1", i.e. if there are timeouts.
- Use polling only during boot, shutdown, or if requested by the user. Otherwise, use a generation count of GPEs, incremented atomically. This prevents an old status value from being used if the EC is really slow and the same condition (i.e. multiple IBEs for a write transaction) is being checked. - Check for and run the query handler directly if the SCI bit is set in the status register during boot. Previously, the query handler wouldn't run until interrupts were finally enabled late in boot. - During boot and after starting a command, check if the event appears to already have occurred before we even start waiting. If so, it's possible the EC is very slow and we might accept an old status value. Print a warning in this case. Once we've booted, interrupt-driven mode should work just fine but polled mode could be unreliable. There's not much more we can do about this until interrupts are enabled during boot. - In the above case, we also do one final check if the interrupt-driven mode gets a timeout. If the status is complete, it will force the system back into polled mode since interrupt mode doesn't work. For polled mode during boot, if the status appears to be already complete before beginning the check loop, it waits 10 us before actually checking the status, just in case the EC is really slow and hasn't gotten to work on the new request yet. - Use upper-case hex for the _Qxx method - Use device_printf for errors, don't hide them under verbose - Increase default total timeout to 750 ms and decrease polling interval to 5 us. - Don't pass the status value via the softc. Just read it directly. - Remove the mutex. We use the sx lock for transaction serialization with the query handler. - Remove the Intel copyright notice as no code of theirs was ever present in this file (verified against rev 1.1) - Allow KTR module-only builds for ease of testing

Dynamically choose the quality of the ACPI timer depending on whether the fast or safe/slow method is in use. Fast remains at 1000, slow is now at 850 (always preferred to TSC). Since the HPET has proven slower than ACPI-fast on some systems, drop its quality to 900. In the future, it is hoped that HPET performance will improve as it is the main timer Intel supports. HPET may move back to 2000 in -current once RELENG_7 is branched to ensure that it gets tested.

Update the suspend/resume user API while maintaining backwards compat.
Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd).
Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting

Despite several examples in the kernel, the third argument of sysctl_handle_int is not sizeof the int type you want to export. The type must always be an int or an unsigned int.

In a few places this was sysctl_handle_int was being used on 64 bit types, which would truncate the value to be exported. In these cases use sysctl_handle_quad to export them and change the format to Q so that sysctl(1) can still print them.

Disable CPU idle states during suspend and reenable them during resume. While in the suspend path, this means the idle thread will just return immediately rather than trying to enter C1-n. This helps in the case where the chipset is powered down before the rest of the system and reads from the cpu sleep registers begin returning immediately, causing the logic that catches bad C2/C3 behavior to kick in.

AcpiAcquireGlobalLock() can sometimes sleep if the mutex is contested. The global lock is a memory region shared with the BIOS and thus has some strange behavior like the fact that the sleep is 1 ms max. We use standard mutexes to synchronize with the SCI so acquiring the global lock after locking the mutex resulted in a witness warning.
To deal with this for now, acquire the global lock before all other locks, similar to Giant. This should fix the witness "sleeping with mutex held" issue on boot that occurred after the last ACPI-CA import. In the future, we hope to move to the new mutex interface in ACPI-CA instead of the pseudo-semaphore version we have now.

Revamp the MSI/MSI-X code a bit to achieve two main goals: - Simplify the amount of work that has be done for each architecture by pushing more of the truly MI code down into the PCI bus driver. - Don't bind MSI-X indicies to IRQs so that we can allow a driver to map multiple MSI-X messages into a single IRQ when handling a message shortage.
The changes include: - Add a new pcib_if method: PCIB_MAP_MSI() which is called by the PCI bus to calculate the address and data values for a given MSI/MSI-X IRQ. The x86 nexus drivers map this into a call to a new 'msi_map()' function in msi.c that does the mapping. - Retire the pcib_if method PCIB_REMAP_MSIX() and remove the 'index' parameter from PCIB_ALLOC_MSIX(). MD code no longer has any knowledge of the MSI-X index for a given MSI-X IRQ. - The PCI bus driver now stores more MSI-X state in a child's ivars. Specifically, it now stores an array of IRQs (called "message vectors" in the code) that have associated address and data values, and a small virtual version of the MSI-X table that specifies the message vector that a given MSI-X table entry uses. Sparse mappings are permitted in the virtual table. - The PCI bus driver now configures the MSI and MSI-X address/data registers directly via custom bus_setup_intr() and bus_teardown_intr() methods. pci_setup_intr() invokes PCIB_MAP_MSI() to determine the address and data values for a given message as needed. The MD code no longer has to call back down into the PCI bus code to set these values from the nexus' bus_setup_intr() handler. - The PCI bus code provides a callout (pci_remap_msi_irq()) that the MD code can call to force the PCI bus to re-invoke PCIB_MAP_MSI() to get new values of the address and data fields for a given IRQ. The x86 MSI code uses this when an MSI IRQ is moved to a different CPU, requiring a new value of the 'address' field. - The x86 MSI psuedo-driver loses a lot of code, and in fact the separate MSI/MSI-X pseudo-PICs are collapsed down into a single MSI PIC driver since the only remaining diff between the two is a substring in a bootverbose printf. - The PCI bus driver will now restore MSI-X state (including programming entries in the MSI-X table) on device resume. - The interface for pci_remap_msix() has changed. Instead of accepting indices for the allocated vectors, it accepts a mini-virtual table (with a new length parameter). This table is an array of u_ints, where each value specifies which allocated message vector to use for the corresponding MSI-X message. A vector of 0 forces a message to not have an associated IRQ. The device may choose to only use some of the IRQs assigned, in which case the unused IRQs must be at the "end" and will be released back to the system. This allows a driver to use the same remap table for different shortage values. For example, if a driver wants 4 messages, it can use the same remap table (which only uses the first two messages) for the cases when it only gets 2 or 3 messages and in the latter case the PCI bus will release the 3rd IRQ back to the system.

Optimize sx locks to use simple atomic operations for the common cases of obtaining and releasing shared and exclusive locks. The algorithms for manipulating the lock cookie are very similar to that rwlocks. This patch also adds support for exclusive locks using the same algorithm as mutexes.
A new sx_init_flags() function has been added so that optional flags can be specified to alter a given locks behavior. The flags include SX_DUPOK, SX_NOWITNESS, SX_NOPROFILE, and SX_QUITE which are all identical in nature to the similar flags for mutexes.
Adaptive spinning on select locks may be enabled by enabling the ADAPTIVE_SX kernel option. Only locks initialized with the SX_ADAPTIVESPIN flag via sx_init_flags() will adaptively spin.
The common cases for sx_slock(), sx_sunlock(), sx_xlock(), and sx_xunlock() are now performed inline in non-debug kernels. As a result, <sys/sx.h> now requires <sys/lock.h> to be included prior to <sys/sx.h>.
The new kernel option SX_NOINLINE can be used to disable the aforementioned inlining in non-debug kernels.
The size of struct sx has changed, so the kernel ABI is probably greatly disturbed.

Check the _TMP value for sanity also. On some systems (HP NX laptops), the EC occasionally times out and provides bogus values (3000C). This change prevents those systems from prematurely shutting down while we work on the underlying problem. Also, bump the sanity value to 0...200C from 0...150C.

Rework EC I/O approach. Implement burst mode, including proper handling of case where it asynchronously exits burst mode on its own. Handle different values of hz in sleep loop. Provide more debugging options to tune EC behavior. These tunables/sysctls may be temporary and are not for user access if the EC is working properly. Burst mode is now on by default for testing and the poll interval has been increased from 100 to 500 us and total timeout from 100 to 500 ms.
Hopefully this should be the first step of addressing reports of timeout errors during battery or thermal access, especially on HP/Compaq laptops. It is reasonably stable and should not cause a loss of functionality or performance on systems that were previously working. Testing shows an increase of responsiveness by ~75% on one system.

Expand the MSI/MSI-X API to address some deficiencies in the MSI-X support. - First off, device drivers really do need to know if they are allocating MSI or MSI-X messages. MSI requires allocating powerof2() messages for example where MSI-X does not. To address this, split out the MSI-X support from pci_msi_count() and pci_alloc_msi() into new driver-visible functions pci_msix_count() and pci_alloc_msix(). As a result, pci_msi_count() now just returns a count of the max supported MSI messages for the device, and pci_alloc_msi() only tries to allocate MSI messages. To get a count of the max supported MSI-X messages, use pci_msix_count(). To allocate MSI-X messages, use pci_alloc_msix(). pci_release_msi() still handles both MSI and MSI-X messages, however. As a result of this change, drivers using the existing API will only use MSI messages and will no longer try to use MSI-X messages. - Because MSI-X allows for each message to have its own data and address values (and thus does not require all of the messages to have their MD vectors allocated as a group), some devices allow for "sparse" use of MSI-X message slots. For example, if a device supports 8 messages but the OS is only able to allocate 2 messages, the device may make the best use of 2 IRQs if it enables the messages at slots 1 and 4 rather than default of using the first N slots (or indicies) at 1 and 2. To support this, add a new pci_remap_msix() function that a driver may call after a successful pci_alloc_msix() (but before allocating any of the SYS_RES_IRQ resources) to allow the allocated IRQ resources to be assigned to different message indices. For example, from the earlier example, after pci_alloc_msix() returned a value of 2, the driver would call pci_remap_msix() passing in array of integers { 1, 4 } as the new message indices to use. The rid's for the SYS_RES_IRQ resources will always match the message indices. Thus, after the call to pci_remap_msix() the driver would be able to access the first message in slot 1 at SYS_RES_IRQ rid 1, and the second message at slot 4 at SYS_RES_IRQ rid 4. Note that the message slots/indices are 1-based rather than 0-based so that they will always correspond to the rid values (SYS_RES_IRQ rid 0 is reserved for the legacy INTx interrupt). To support this API, a new PCIB_REMAP_MSIX() method was added to the pcib interface to change the message index for a single IRQ.

Re-work Cx handling to be per-cpu and asymmetrical, fixing support on modern dual-core systems as well.
- Parse the _CST packages for each cpu and track all the states individually, on a per-cpu basis.
- Revert to generic FADT/P_BLK based Cx control if the _CST package is not present on all cpus. In that case, the new driver will still support per-cpu Cx state handling. The driver will determine the highest Cx level that can be supported by all the cpus and configure the available Cx state based on that.
- Fixed the case where multiple cpus in the system share the same registers for Cx state handling. To do that, added a new flag parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that enable the caller to add the RF_SHAREABLE flag. This flag could also be useful to other callers (acpi_throttle?) in the tree but this change is not yet made.
- For Core Duo cpus, both cores seems to be taken out of C3 state when any one of the cores need to transition out. This broke the short sleep detection logic. It is disabled now if there is more than one cpu in the system for now as it fixed it in my case. This quirk may need to be re-enabled later differently.
- Added support to control cx_lowest on a per-cpu basis. There is still a generic cx_lowest to enable changing cx_lowest for all cpus with a single sysctl and for ease of use. Sample output for the new sysctl:
dev.cpu.0.cx_supported: C1/1 C2/1 C3/57 dev.cpu.0.cx_lowest: C3 dev.cpu.0.cx_usage: 0.00% 43.16% 56.83% dev.cpu.1.cx_supported: C1/1 C2/1 C3/57 dev.cpu.1.cx_lowest: C3 dev.cpu.1.cx_usage: 0.00% 45.65% 54.34% hw.acpi.cpu.cx_lowest: C3

First cut at MI support for PCI Message Signalled Interrupts (MSI): - Add 3 new functions to the pci_if interface along with suitable wrappers to provide the device driver visible API: - pci_alloc_msi(dev, int *count) backed by PCI_ALLOC_MSI(). '*count' here is an in and out parameter. The driver stores the desired number of messages in '*count' before calling the function. On success, '*count' holds the number of messages allocated to the device. Also on success, the driver can access the messages as SYS_RES_IRQ resources starting at rid 1. Note that the legacy INTx interrupt resource will not be available when using MSI. Note that this function will allocate either MSI or MSI-X messages depending on the devices capabilities and the 'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. Also note that the driver should activate the memory resource that holds the MSI-X table and pending bit array (PBA) before calling this function if the device supports MSI-X. - pci_release_msi(dev) backed by PCI_RELEASE_MSI(). This function releases the messages allocated for this device. All of the SYS_RES_IRQ resources need to be released for this function to succeed. - pci_msi_count(dev) backed by PCI_MSI_COUNT(). This function returns the maximum number of MSI or MSI-X messages supported by this device. MSI-X is preferred if present, but this function will honor the 'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. This function should return the largest value that pci_alloc_msi() can return (assuming the MD code is able to allocate sufficient backing resources for all of the messages). - Add default implementations for these 3 methods to the pci_driver generic PCI bus driver. (The various other PCI bus drivers such as for ACPI and OFW will inherit these default implementations.) This default implementation depends on 4 new pcib_if methods that bubble up through the PCI bridges to the MD code to allocate IRQ values and perform any needed MD setup code needed: - PCIB_ALLOC_MSI() attempts to allocate a group of MSI messages. - PCIB_RELEASE_MSI() releases a group of MSI messages. - PCIB_ALLOC_MSIX() attempts to allocate a single MSI-X message. - PCIB_RELEASE_MSIX() releases a single MSI-X message. - Add default implementations for these 4 methods that just pass the request up to the parent bus's parent bridge driver and use the default implementation in the various MI PCI bridge drivers. - Add MI functions for use by MD code when managing MSI and MSI-X interrupts: - pci_enable_msi(dev, address, data) programs the MSI capability address and data registers for a group of MSI messages - pci_enable_msix(dev, index, address, data) initializes a single MSI-X message in the MSI-X table - pci_mask_msix(dev, index) masks a single MSI-X message - pci_unmask_msix(dev, index) unmasks a single MSI-X message - pci_pending_msix(dev, index) returns true if the specified MSI-X message is currently pending - Save the MSI capability address and data registers in the pci_cfgreg block in a PCI devices ivars and restore the values when a device is resumed. Note that the MSI-X table is not currently restored during resume. - Add constants for MSI-X register offsets and fields. - Record interesting data about any MSI-X capability blocks we come across in the pci_cfgreg block in the ivars for PCI devices.

First pass at allowing memory to be mapped using cache modes other than WB (write-back) on x86 via control bits in PTEs and PDEs (including making use of the PAT MSR). Changes include: - A new pmap_mapdev_attr() function for amd64 and i386 which takes an additional parameter (relative to pmap_mapdev()) specifying the cache mode for this mapping. Note that on amd64 only WB mappings are done with the direct map, all other modes result in a private mapping. - pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached) mappings rather than WB. Previously we relied on the BIOS setting up MTRR's to enforce memio regions being treated as UC. This might make hw.cbb_start_memory unnecessary in some cases now for example. - A new pmap_mapbios()/pmap_unmapbios() API has been added to allow places that used pmap_mapdev() to map non-device memory (such as ACPI tables) to do so using WB as before. - A new pmap_change_attr() function for amd64 and i386 that changes the caching mode for a range of KVA.

Don't attach special devices in the order they appear in the AML tree. If the embedded controller exists before the sysresource devices, for example, it will be attached first. Instead, let the normal device order function work as we first desired. [1]
There still remained a problem where we couldn't allocate resources in acpi0 that were passed up by the sysresource pseudo-devices. These devices had to probe/attach first to give their resources to acpi, then acpi would allocate them before probing/attaching other devices. To work around this, we attach them from acpi_sysres_alloc(). A better approach would be to implement multi-pass probe/attach in newbus but that's a much bigger task.

Add a blacklist for bad IO ports that AML should never touch. It seems some systems were designed so that AML writes to various resources shared with OS drivers, including the RTC, PIC, PCI, etc. These writes could collide with writes by the OS and should never be performed. For now, we print a message if such an access occurs, but do not block it. To block the access, the tunable "debug.acpi.block_bad_io" can be set to 1. In the future, we will flip the switch and this will become the default.
Information about this problem was found in Microsoft KB 283649. They block IO accesses if the BIOS indicates via _OSI that it is Windows 2001 or higher. They always block accesses to the PIC, cascaded PIC, and ELCRs, no matter how old the BIOS.

This allows the creation of 1 or more threads that will service a single taskqueue. Also rework the taskqueue_create() API to remove the API change that was introduced a while back. Creating a taskqueue doesn't rely on the presence of a process structure, and the proc mechanics are much better encapsulated in taskqueue_start_threads(). Also clean up the taskqueue_terminate() and taskqueue_free() functions to safely drain pending tasks and remove all associated threads.
The TASKQUEUE_DEFINE and TASKQUEUE_DEFINE_THREAD macros have been changed to use the new API, but drivers compiled against the old definitions will still work. Thus, recompiling drivers is not a strict requirement.

Fix the code to look up the BIOS IRQ for a given link device by reading the IRQ set by the BIOS in existing devices to actually get the correct bus number of the child PCI bus. I was not reading the bus number from the bridge device correctly. The __BUS_ACCESSOR() macros (from which pcib_get_bus() is built) assume that the passed in argument is a child device. However, at the time I'm reading the bus there is no child device yet, so I was passing in the pcib device as the child device. The parent of the pcib device probably returned an error in the case of a host bridge, thus resulting in random stack garbage for the bus number. For PCI-PCI bridges, the bus number being used was actually the subvendor of the PCI-PCI bridge device itself.

*sigh* Revert stuff that wasn't supposed to be committed. The acpi_resource change was a minor nit offered as an early candidate for the recent ACPICA import problem and the acpi.c change is one I need to test still that makes the ordered probing of system devices actually work as advertised (probe devices in order based on the type of device rather than in the order we encounter them in the device tree).

Work around at least one busted BIOS. If we get a source index in a _PRT entry that is not zero, assume that it is really a hard-wired IRQ (commonly used for APIC routing) and not a source index. In practice, we've only ever seen source indices of 0 for legitimate non-hard-wired _PRT entries.

Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat.
- Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters.
- Disambiguate some collisions by adding subsystem prefixes to some memory types.
- Generally prefer lower case to upper case.
- If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases.
Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names.

If we're trying to use C2/3 and reads from the register are returning immediately, back off to the next higher Cx sleep state. Some machines with a Via chipset report a valid C3 but a register read doesn't actually halt the CPU. This would cause the machine to appear unresponsive as it repeatedly called cpu_idle() which immediately returned. Causing interrupts (i.e. by pressing the power button) would cause the system to make forward progress, showing that it wasn't actually hung.
Also, enable interrupts a little earlier. We don't need them disabled to calculate the delta time for the read.

Import ACPI smart battery support. Newer systems (Acer, mostly) do not support the CM-battery interface. Smart batteries can eventually be supported without ACPI via a separate SMBus interface. The ACPI interface uses the embedded controller for reading/writing to the SMBus, and normal ASL definitions for locating the battery controller (since SMBus can't be enumerated.) Also import definitions for the smart battery interface.
This was written by Hans Petter Selasky with minor cleanups from myself.

Cleanups and support code for importing smart battery support.
* Use ACPI_BATT_UNKNOWN instead of constants * Use maxunit instead of a count of devices since we may have sparse battery devices in the future. Only userland should be using unit numbers anyway, so provide a translation function. (Kernel use of batteries should be restricted to looking up a device_t and calling methods directly. * Don't check acpi_BatteryIsPresent() in acpi_battery. Leave it up to the hardware-specific driver (i.e. cmbat) since smart batteries seem to not report the "battery present" flag. * Convert mA to mW if the battery uses those units. CM-batteries only used mW so this deficiency went unnoticed. * Clean strings reported in the battery info from any control chars. * Only dereference the unit from ioctl_arg if the full struct is present. Unit wouldn't have been used later if it wasn't present but this is cleaner. Translate the unit if it's not ACPI_BATTERY_ALL_UNITS. * bzero structs before returning them to usermode for future compat.
Most of this work was submitted by Hans Petter Selasky and then majorly reworked by myself.

Commit a workaround to a problem with resource allocation. This helps with some Dell servers that booted w/o a problem[*] on 5.4, but failed with 6.0-BETA.
On the PCI bus, when we do lazy resource allocation, we narrow the range requested as we pass through bridges to reflect how the bridges are programmed and what addresses they pass. However, when we're doing an allocation on a bus that's directly connected to a host bridge, no such translation can take place. We already had a fallback range for memory requests, but none for ioports. As such, provide a fallback for I/O ports so we don't allocate location 0, which will have undesired side effects when the resources are actually used.
This fixes a problem with booting a Dell server with usb in the kernel. However, it is an unsatisfying solution. I don't like the hard coded value, and I think we should start narrowing the resources returned to not be in the so-called isa alias area (where the ranage & 0x0300 must be 0 iirc). Doing such filtering will have to wait for another day.
This may be a good 6 candidate, maybe after its had a chance to be refined.

Rewrite the acpi_battery interface to allow for other battery types (i.e., smart battery) and fix various bugs found during the cleanup.
API changes: * kernel access: Access to individual batteries is now via devclass_find("battery"). Introduce new methods ACPI_BATT_GET_STATUS (for _BST-formatted data) and ACPI_BATT_GET_INFO (for _BIF-formatted data). The helper function acpi_battery_get_battinfo() now takes a device_t instead of a unit # argument. If dev is NULL, this signifies all batteries.
* ioctl access: The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been removed. Since there is now no need for a mapping between "virtual" unit and physical unit, usermode programs can just specify the unit directly and skip the old translation steps. In fact, acpiconf(8) was actually already doing this and virtual unit was the same as physical unit in all cases since there was previously only one battery type (acpi_cmbat). Additionally, we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all batteries, if they provide the associated methods.
* apm compatibility device/ioctls: no change * sysctl: no change
Since most third-party applications use the apm(4) compat interface, there should be very few affected applications (if any).

In newbus land, ivars can only be accessed for direct child, or when the driver has unholy private knowledge of its great-*cgrandchildren. The ACPI allocation routine lacked such knowledge when it tried to do a default allocation for all descendants, rather than just its immeidate children, so would access grandchild's ivar in an unsafe way. This could lead to a panic when devices were present which had no addresses setup by the BIOS, but which were later allocated in a lazy manner via pci_alloc_map. As such, only do the default allocation adjustments for immediate children. The manner that acpi_sysres_find accesses the resource list, used later in acpi_alloc_resource, is safe and proper so no additional test is needed there.
This fixes a panic when probing an disabled ata controller on some newer intel blades.

- Add support for link devices where _CRS just outright fails to execute. For such devices, we require _PRS to exist and we warn if any of the resources in _PRS are not IRQ resources (since we'll have no way of knowing which of those resources to use without a working _CRS). When it does come time to set resources, we build up a resource buffer from scratch as we do for devices with _CRS that only have IRQ resources. - Fix a bug with setting extended IRQ resources where we set the IRQ value in the wrong resource structure meaning that whichever IRQ was listed in _PRS was used instead. This might fix some weird issues on certain boxes where IRQs > 16 don't seem to work when using ACPI. - Fix a bug with how we walked the resource buffer after _SRS to call config_intr() in that the 'end' variable was not properly updated, so we could either terminate the loop early or loop after the end of the buffer.

- Do a better job of handling any Dependent Functions (aka DPFs) that appear in the _PRS or _CRS of link devices. If faced with multiple DPFs in a _PRS, we just use the first one. We assume that if _CRS has DPF tags they only contain a single set since multiple DPFs wouldn't make any sense. In practice, the only DPFs I've seen so far for link devices are that the one IRQ resource is surrounded by a DPF tag pair for no apparent reason, and this should handle that case fine now. - Only allocate link structures for IRQ resources for link devices rather than allocating a link structure for every resource.

Make sure the link array is big enough to hold both _CRS and _PRS resource lists. It used to be sized based only on _CRS, hence _PRS could perform an out-of-bounds access if it was larger (i.e., when there are dependent functions). Add asserts to detect this case. Note, this is only a temporary fix and I believe _PRS and _CRS should have separate arrays.
Also, fix a typo where the wrong irq was being check for the APIC case.

Rework the ACPI PCI link code. - Use a new-bus device driver for the ACPI PCI link devices. The devices are called pci_linkX. The driver includes suspend/resume support so that the ACPI bridge drivers no longer have to poke the links to get them to handle suspend/resume. Also, the code to handle which IRQs a link is routed to and choosing an IRQ when a link is not already routed is all contained in the link driver. The PCI bridge drivers now ask the link driver which IRQ to use once they determine that a _PRT entry does not use a hardwired interrupt number. - The new link driver includes support for multiple IRQ resources per link device as well as preserving any non-IRQ resources when adjusting the IRQ that a link is routed to. - The entire approach to routing when using a link device is now link-centric rather than pci bus/device/pin specific. Thus, when using a tunable to override the default IRQ settings, one now uses a single tunable to route an entire link rather than routing a single device that uses the link (which has great foot-shooting potential if the user tries to route the same link to two different IRQs using two different pci bus/device/pin hints). For example, to adjust the IRQ that \_SB_.LNKA uses, one would set 'hw.pci.link.LNKA.irq=10' from the loader. - As a side effect of having the link driver, unused link devices will now be disabled when they are probed. - The algorithm for choosing an IRQ for a link that doesn't already have an IRQ assigned is now much closer to the one used in $PIR routing. When a link is routed via an ISA IRQ, only known-good IRQs that the BIOS has already used are used for routing instead of using probabilities to guess at which IRQs are probably not used by an ISA device. One change from $PIR is that the SCI is always considered a viable ISA IRQ, so that if the BIOS does not setup any IRQs the kernel will degenerate to routing all interrupts over the SCI. For non ISA IRQs, interrupts are picked from the possible pool using a simplistic weighting algorithm.

These drivers don't appear to do anything i386 specific, so move them to dev/acpi_support. Move config lines to files so that those architectures that don't support kernel modules can build them into the kernel.

Don't change the state of the system in acpi_tz_establish(). Before, we would turn off all fans when initializing a zone.

Also, note that running _SCP can generate the same notify.
Since we need to make sure old fan references are turned off when getting new ones, run acpi_tz_monitor() first. This will turn off any unneeded fans. Then, check for new settings. After that, run acpi_tz_monitor() again to turn on/off any fans referenced by the new settings.

Rework sysresource management. Instead of having each sysresource object hold its own values, pass them up to the parent (acpi0) and merge/uniq them on the way. After the namespace evaluation, acpi will reserve these resources and manage them via rman before bus_generic_probe() and bus_generic_attach(). This is necessary because some systems specify conflicting resources in separate sysresource objects. It's also cleaner in that the interface between sysresource and acpi is now merely the parent's resource list. This code handles the following cases:
1. Unique resource: add it to the parent via bus_set_resource(). 2. New wholly contained in old: discard new. 3. New tail overlaps old head: grow old head downward. AND/OR 4. New head overlaps old tail: grow old tail upward.

Correctly handle BIOS resources that are duplicated (!). There are many systems that have overlapping regions specified in their sysresource objects. This patch fixes ATA DMA and acpi_timer allocation for such sysctems. It should eventually be moved to resource_list_add() if it is a valid generalized approach. The minimal approach for 5.3 is:
"Loop through all current resources to see if the new one overlaps any existing ones. If so, the old one always takes precedence and the new one is adjusted (or rejected). We check for three cases:
1. Tail of new resource overlaps head of old resource: truncate the new resource so it is contiguous with the start of the old. 2. New resource wholly contained within the old resource: error. 3. Head of new resource overlaps tail of old resource: truncate the new resource so it is contiguous, following the old."

Notifies only do a wakeup and let acpi_tz_thread() do the actual work. This path is cleaner and allows locking since the call path is now always a D.A.G. * Add the acpi_tz_signal() function to set flags and wake the thread. * Remove the tz_tmp_updating flag since calls are serialized by acpi_tz_thread(). * Remove Giant locking.

Re-work ACPI PCI IRQ routing (_PRT, link devices). The old approach was incomplete in that the PRT routing was not aware of link programming. Fix this by doing all routing through the link devices. The new algorithm for setting up links is:
1. Read _CRS to get current setting. If invalid (not in _PRS), then set to 0. 2. Attempt to call _DIS on the link. If successful, mark the link as not routed. Otherwise, assume it still is.
Then when a routing request occurs:
3. Update weights for all IRQs 4. Attempt to route the initial IRQ if valid 5. If that fails, walk through the sorted list, attempting to route IRQs. 6. Configure the trigger/polarity based on _PRS.
Other changes: * Add acpi_pci_find_prt() to look up the PRT entry for a given device and acpi_pci_link_route() to select/route the best IRQ for it. * Remove duplicated code in acpi_pcib_route_interrupt() that picked the first IRQ from _PRS. * Remove unneeded arguments from acpi_pcib_resume() and friends. * Ignore _STA on link devices but report if it seems strange. * Add a prt_source handle to the PRT structure since the ACPI struct ACPI_PCI_ROUTING_TABLE uses a fixed-size entry for it. We'll need to dynamically size this object if we want to use it the same way ACPI-CA does. Null-terminate the source.

Work around non-compliant BIOS PCI link devices. Some systems have the following behavior:
* Link devices return invalid status (_STA) values. The results are very unreliable -- sometimes never present. Just ignore the status and pick the best configuration from _PRS.
* Link devices return invalid current settings (_CRS). Even after setting the link value, many systems still return a different setting for _CRS. When setting an IRQ, don't bother to check _CRS to see if we succeeded. Note that we still check _CRS before routing and this should be addressed as well.
Since this is a sensitive area, leave the old behavior accessible via uncommenting the define for ACPI_OLD_PCI_LINK at the top of the file. Once this has been thoroughly tested, this option and the code it covers will be removed.
Thanks to Len Brown at Intel for informing us of these issues as he worked around them in Linux.

Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices.
Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

Don't assume that the current setting (_CRS) of a PCI link device is correct. Instead, check it against the possible settings (_PRS) when the link is probed. This is important when using APIC mode but link devices still have PIC mode settings. This is also what Linux does.

Update the new suspend/resume GPE methods to properly limit the GPE based on the destination sleep state. Add a method to restore the old state on resume. This is needed for the case of suspending to a very low state disabling a GPE (i.e. S4), resuming, and then suspending to a higher state (i.e. S3). This case should now keep the proper GPEs enabled.

Restructure the wake GPE API. Now there are three functions:
acpi_wake_init: Evaluate _PRW and set the GPE type acpi_wake_set_enable: Enable or disable a device's GPE. acpi_wake_sleep_prep: Perform any last-minute changes to the device to prepare it for entering the given sleep state.
Also, walk the entire namespace when transitioning to a sleep state, disabling any GPEs which aren't appropriate for the given state. Transition acpi_lid and acpi_button to the new API.
This clears the way for non-ACPI-aware devices to wake the system (i.e. modems) and fixes a problem where systems power up after shutdown when a GPE is triggered.

Changes to implement 20040514:
* Add calls to AcpiSetGpeType. We use wake/run as the type for lid and button switches since wake-only causes Thinkpads to immediately wake on the second suspend. Note that with wake/run, some systems return both wake and device-specific notifies so we don't register for system notifies for lid and button switches. * Remove the hw.acpi.osi_method tunable since it is not needed. * Always print unknown notifies for all types. * Add more cleanup for the EC if it fails to attach. * Use the GPE handle now that we parse it. This allows GPEs to be defined in AML GPE blocks. * Always use ACPI_NOT_ISR since it's ok to acquire a mutex in our thread which processes queued requests.

Fix several bugs where 32-bit timers and wraparound were not properly supported. Symptoms of this bug included unnecessary use of ACPI-safe and a dmesg that has deltas of about 2^24:
ACPI timer looks BAD min = 2, max = 16777206, width = 16777204 ACPI timer looks BAD min = 2, max = 7, width = 5 ACPI timer looks GOOD min = 4, max = 5, width = 1 ACPI timer looks BAD min = 2, max = 16777206, width = 16777204 ACPI timer looks BAD min = 2, max = 7, width = 5 ACPI timer looks BAD min = 2, max = 16777210, width = 16777208 ACPI timer looks BAD min = 4, max = 16777189, width = 16777185 ACPI timer looks GOOD min = 4, max = 5, width = 1 ACPI timer looks BAD min = 2, max = 7, width = 5 ACPI timer looks BAD min = 4, max = 16777189, width = 16777185
To fix this: * Use a 32 bit timecounter mask when the timer is 32 bits. * In test_counter(), use the acpi_TimerDelta function which handles 24/32 bit timers and wraparound.
Miscellaneous fixes: * Use C99 initializers for timecounter struct. * Use u_int and uint32_t where appropriate instead of unsigned. * Remove whitespace-only lines * Remove the old PIIX4 PCI workaround. The timecounter testing code has been in use for long enough to prove it's functional.

If the temperature is at _HOT or _CRT for 3 sequential readings, shutdown the system. Also, decrease the poll interval to 10 seconds from 30 seconds. This is needed because some systems will report an invalid high temperature for one poll cycle. It is suspected this is due to the embedded controller timing out. A typical value is 138C for one cycle on a system that is otherwise 65C. This prevents the system from prematurely shutting down after one invalid reading. It will still shut down after 30 seconds of high temperature, which is the same as previous default behavior.

Finally, return pc_cpuid in *cpu_id and use that as our primary key.
* Use pc_cpuid as our unique key because we know it is valid since MD code set it. The values for ProcId in the ASL and MADT don't match up on some machines (!), forcing us to fall back to ordered probing in that case.
* Remove some #ifdef SMP since the refcount doesn't hurt performance and will be needed for dynamic _CST objects. Only one #ifdef SMP (for smp_rendezvous) remains.

* In the !SMP case, don't use the processor id filled out by the MADT since there can only be one processor. This was causing a panic in acpi_cpu_idle if the id was 1 since the data was being dereferenced from cpu_softc[1] even though the actual data was in cpu_softc[0] (which is correct).
* Rework the initialization functions so that cpu_idle_hook is written late in the boot process.
* Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables. This will help SMP boxes that have _CST or multiple P_BLKs. No such boxes are known at this time.
* Always allocate the C1 state, even if the P_BLK is invalid. This means we will always take over idling if enabled. Remove the value -1 as valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt.
* Reduce locking for the throttle initialization case to around the write to the smi_cmd port. Add disabled code to write the CST_CNT. It will be enabled once _CST re-evaluation is tested (post 5.2R).

It will be used in the sparc64 ofw_pcibus driver, which will be committed shortly.
Make use of this method in the generic implementation, and add it to the method table of bus drivers derived from the PCI one.

o Don't announce that the timer is good when in fact it isn't timing at all (ie reads yield constant values). Display the width as the difference between max and min so that constant timers have width zero. o Get the address of the timer from the XPmTmrBlk field instead of the V1_PmTmrBlk field. The former is a generic address and can specify a memory mapped I/O address. Remove <machine/bus_pio.h> to account for this. The timer is now properly configured on machines with ACPI v2 tables, whether PIO or MEMIO. Note that the acpica code converts v1 tables into v2 tables so the address is always present in XPmTmrBlk. o Replace the TIMER_READ macro with a call to the read_counter() function and add a barrier to make sure that we observe proper ordering of the reads.

According to the ACPI spec, the bus number of the child PCI bus of a host to PCI bridge can be read be evaluating the _BBN method of the host to PCI device. Unfortunately, there appear to be some lazy/ignorant/moronic/ whatever BIOS writers that return 0 for _BBN for all host to PCI bridges in the system. On a system with a single host to PCI bridge this is not a problem as the child bus of that single bridge will be bus 0 anyway. However, on systems with multiple host to PCI bridges and l/i/m/w BIOS writers this is a major problem resulting in all but the first host to PCI bridge failing to attach. So, this adds a workaround.
If the _BBN of a host to PCI bridge is zero and pcib0 already exists and is not us, the we use _ADR to look up our PCI function and slot (we currently assume we are on bus 0) and use that to call host_pcib_get_busno() to try and extract our bus number from config registers on the host to PCI bridge device. If that fails, then we make an evil assumption that ACPI's _SB_ namespace lays out the host to PCI bridges in ascending order and use our pcib unit number as our bus number.

Some kernel threads try to do significant work, and the default KSTACK_PAGES doesn't give them enough stack to do much before blowing away the pcb. This adds MI and MD code to allow the allocation of an alternate kstack who's size can be speficied when calling kthread_create. Passing the value 0 prevents the alternate kstack from being created. Note that the ia64 MD code is missing for now, and PowerPC was only partially written due to the pmap.c being incomplete there. Though this patch does not modify anything to make use of the alternate kstack, acpi and usb are good candidates.

Overhaul the ACPI PCI bridge driver a bit: - Add an ACPI PCI-PCI bridge driver (the previous driver just handled Host-PCI bridges) that is a PCI driver that is a subclass of the generic PCI-PCI bridge driver. It overrides probe, attach, read_ivar, and pci_route_interrupt. - The probe routine only succeeds if our parent is an ACPI PCI bus which we test for by seeing if we can read our ACPI_HANDLE as an ivar. - The attach routine saves a copy of our handle and calls the new acpi_pcib_attach_common() function described below. - The read_ivar routine handles normal PCI-PCI bridge ivars and adds an ivar to return the ACPI_HANDLE of the bus this bridge represents. - The route_interrupt routine fetches the _PRT (PCI Interrupt Routing Table) from the bridge device's softc and passes it off to acpi_pcib_route_interrupt() to route the interrupt. - Split the old ACPI Host-PCI bridge driver into two pieces. Part of the attach routine and most of the route_interrupt routine remain in acpi_pcib.c and are shared by both ACPI PCI bridge drivers. - The attach routine verifies the PCI bridge is present, reads in the _PRT for the bridge, and attaches the child PCI bus. - The route_interrupt routine uses the passed in _PRT to route a PCI interrupt. The rest of the driver is the ACPI Host-PCI bridge specific bits that live in acpi_pcib_acpi.c. - We no longer duplicate pcib_maxslots but use it directly. - The driver now uses the pcib devclass instead of its own devclass. This means that PCI busses are now only children of pcib devices. - Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar of the child bus. - Fetch the _PRT for routing PCI interrupts directly from our softc instead of walking the devclass to find ourself and then fetch our own softc.
With this change and the new ACPI PCI bus driver, ACPI can now properly route interrupts for devices behind PCI-PCI bridges. That is, the Itanium2 with like 10 PCI busses can now boot ok and route all the PCI interrupts. Hopefully this will also fix problems people are having with CardBus bridges behind PCI-PCI bridges not properly routing interrupts when ACPI is used.

Add an ACPI PCI bus driver that is a subclass of the generic PCI bus driver. This driver overrides the probe, attach, and read_ivar methods.
If the parent bridge is an ACPI PCI bridge, then the probe routine will match, otherwise it will fail. It tests this by seeing if it can get the ACPI_HANDLE ivar from the bridge device.
In the attach routine, it uses pci_add_children() to add all the child devices (but with a slightly larger ivar so it can store ACPI_HANDLE's for child devices) and then walks through the ACPI namespace below the bus device to cache ACPI_HANDLE's for all child devices present in the namespace. It does this by comparing the pci slot and function to the address encoded in _ADR of the devices in the ACPI namespace.
The read_ivar routine passes most requests off to pci_read_ivar() and adds a new request so that the ACPI_HANDLE for a child device can be read.
To add proper power support the power methods can be overridden as well, but that is not currently implemented. Also, there are cases where a device may show in the ACPI namespace as a PCI device that the PCI probe does not find. Currently such devices are ignored.

This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory.

Hide the ACPI counter probing printf behind bootverbose.
The conclusion is that this method really can tell the perfect from the less than perfect ACPI counters.
It is in fact probably a bit more discriminative than that, but we will rather condemn some otherwise perfect counters to the slightly slower "-safe" version, than certify a counter as perfect which will let us down later.

Add a new test_counter() function which tries to determine the width of the inter-value histogram for 2000 samples. If the width is 3 or less for 10 consequtive samples, we trust the counter to be good, otherwise we use the *_safe() method.
This method may be too strict, but the worst which can happen is that we take the performance hit of the *_safe() method when we should not.
Make the *_safe() method more discriminating by mandating that the three samples do not span more than 15 ticks on the counter.
Disable the PCI-ident based probing as a means to recognize good counters.

Tests by numerous people have shown that many chipsets do not properly latch the acpi timer, resulting in weird deltas. The problem is severe enough to adversely effect the timecounter code.
Default to the 'safe' version of the get-timecount function. The probe will override it if a known-good chipset is found. This is temporary until a more complete solution is found.

Change the preemption code for software interrupt thread schedules and mutex releases to not require flags for the cases when preemption is not allowed:
The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent switching to a higher priority thread on mutex releease and swi schedule, respectively when that switch is not safe. Now that the critical section API maintains a per-thread nesting count, the kernel can easily check whether or not it should switch without relying on flags from the programmer. This fixes a few bugs in that all current callers of swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from fast interrupt handlers and the swi_sched of softclock needed this flag. Note that to ensure that swi_sched()'s in clock and fast interrupt handlers do not switch, these handlers have to be explicitly wrapped in critical_enter/exit pairs. Presently, just wrapping the handlers is sufficient, but in the future with the fully preemptive kernel, the interrupt must be EOI'd before critical_exit() is called. (critical_exit() can switch due to a deferred preemption in a fully preemptive kernel.)
I've tested the changes to the interrupt code on i386 and alpha. I have not tested ia64, but the interrupt code is almost identical to the alpha code, so I expect it will work fine. PowerPC and ARM do not yet have interrupt code in the tree so they shouldn't be broken. Sparc64 is broken, but that's been ok'd by jake and tmm who will be fixing the interrupt code for sparc64 shortly.

The API for loading tables changed (we no longer explicitly search for the RSDP, it's now found via a callback).
AcpiOsSleepUsec() went away, use AcpiOsSleep() instead (we could use AcpiOsStall() too)
AcpiFormatException() was changed to make more sense (it behaves like our old acpi_strerror() did), so throw acpi_strerror() away (still #defined in acpivar.h though, we need to sweep these seperately).

Implement PCI interrupt routing using the ACPI data attached to the PCI bus object. This should deal both with already-routed interrupts as well as devices that need an interrupt routed.

When ensuring the destination buffer is truncated for a string obtained from a BIF, use the size of the destinatino buffer, not the length of the string to determine where to put the nul char. As a side effect, the old code would truncate the string by one character while it was possibly overflowing the buffer.

Implement a unified run queue and adjust priority levels accordingly.
- All processes go into the same array of queues, with different scheduling classes using different portions of the array. This allows user processes to have their priorities propogated up into interrupt thread range if need be. - I chose 64 run queues as an arbitrary number that is greater than 32. We used to have 4 separate arrays of 32 queues each, so this may not be optimal. The new run queue code was written with this in mind; changing the number of run queues only requires changing constants in runq.h and adjusting the priority levels. - The new run queue code takes the run queue as a parameter. This is intended to be used to create per-cpu run queues. Implement wrappers for compatibility with the old interface which pass in the global run queue structure. - Group the priority level, user priority, native priority (before propogation) and the scheduling class into a struct priority. - Change any hard coded priority levels that I found to use symbolic constants (TTIPRI and TTOPRI). - Remove the curpriority global variable and use that of curproc. This was used to detect when a process' priority had lowered and it should yield. We now effectively yield on every interrupt. - Activate propogate_priority(). It should now have the desired effect without needing to also propogate the scheduling class. - Temporarily comment out the call to vm_page_zero_idle() in the idle loop. It interfered with propogate_priority() because the idle process needed to do a non-blocking acquire of Giant and then other processes would try to propogate their priority onto it. The idle process should not do anything except idle. vm_page_zero_idle() will return in the form of an idle priority kernel thread which is woken up at apprioriate times by the vm system. - Update struct kinfo_proc to the new priority interface. Deliberately change its size by adjusting the spare fields. It remained the same size, but the layout has changed, so userland processes that use it would parse the data incorrectly. The size constraint should really be changed to an arbitrary version number. Also add a debug.sizeof sysctl node for struct kinfo_proc.

Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:
mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)
similarily, for releasing a lock, we now have:
mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument.
The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind.
Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two:
MTX_QUIET and MTX_NOSWITCH
The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers:
mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively.
Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case.
Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled.
Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those.
Finally, caught up to the interface changes in all sys code.

- Convert a lot of homebrew debugging output to use the ACPI CA debugging infrastructure. It's not perfect, but it's a lot better than what we've been using so far. The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now. We may elect to add some new BSD-specific layers later.
- Make it possible to turn off selective debugging flags or layers by listing them in debug.acpi.layer or debug.acpi.level prefixed with !.
- Fully implement support for avoiding nodes in the ACPI namespace. Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace.
- Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace.
- Add support for ioctl registration. ACPI subsystem components may register ioctl handlers with the /dev/acpi generic ioctl handler, allowing us to avoid the need for a multitude of /dev/acpi* control devices, etc.
