The problematic one in this case is an mSATA SSD hooked up via a mSATA->PATA bridge. With regular hard disks the detection seems to work correctly.

ata_piix: reenable MS Virtual PC guests An earlier commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c ("ata_piix: defer disks to the Hyper-V drivers by default") broke MS Virtual PC guests. Hyper-V guests and Virtual PC guests have nearly identical DMI info. As a result the driver does currently ignore the emulated hardware in Virtual PC guests and defers the handling to hv_blkvsc. Since Virtual PC does not offer paravirtualized drivers no disks will be found in the guest. One difference in the DMI info is the product version. This patch adds a match for MS Virtual PC 2007 and "unignores" the emulated hardware. This was reported for openSuSE 12.1 in bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=737532 Here is a detailed list of DMI info from example guests: hwinfo --bios: virtual pc guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "VS2005R2" Serial: "3178-9905-1533-4840-9282-0569-59" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Asset Tag: "7188-3705-6309-9738-9645-0364-00" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k8 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Asset Tag: "7076-9522-6699-1042-9501-1785-77" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k12 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Asset Tag: "8374-0485-4557-6331-0620-5845-25" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

ata_piix: defer disks to the Hyper-V drivers by default When we are hosted on a Microsoft Hyper-V hypervisor the guest disks are exposed both via the Hyper-V paravirtualised drivers and via an emulated SATA disk drive. In this case we want to use the paravirtualised drivers if we can as they are much more efficient. Note that the Hyper-V paravirtualised drivers only expose the virtual hard disk devices, the CDROM/DVD devices must still be enumerated. Mark the host controller ATA_HOST_IGNORE_ATA to prevent enumeration of disk devices.

With help from Tejun, the problem is found to be caused by 32bit PIO mode, so introduce the quirk patch to disable 32bit PIO on SATA piix for some Sandybridge CPT chipsets. Seth also tested the patch on all five affected chipsets (pci device ID: 0x1c00, 0x1c01, 0x1d00, 0x1e00, 0x1e01), and found the patch does fix the problem.

ata_piix: fix locking around SIDPR access SIDPR window registers are shared across ports and as each access is done in two steps, accesses to different ports under EH may race. This primarily is caused by incorrect host locking in EH context and should be fixed by defining locking requirements for each EH operation which can be used during EH and enforcing them but for now work around the problem by adding a dedicated SIDPR lock and grabbing it for each SIDPR access.

libata-sff: separate out BMDMA irq handler Separate out BMDMA irq handler from SFF irq handler. The misnamed host_intr() functions are renamed to ata_sff_port_intr() and ata_bmdma_port_intr(). Common parts are factored into __ata_sff_port_intr() and __ata_sff_interrupt() and used by sff and bmdma interrupt routines. All BMDMA drivers now use ata_bmdma_interrupt() or ata_bmdma_port_intr() while all non-BMDMA SFF ones use ata_sff_interrupt() or ata_sff_port_intr(). For now, ata_pci_sff_init_one() uses ata_bmdma_interrupt() as it's used by both SFF and BMDMA drivers. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

libata: implement spurious irq handling for SFF and apply it to piix Traditional IDE interface sucks in that it doesn't have a reliable IRQ pending bit, so if the controller raises IRQ while the driver is expecting it not to, the IRQ won't be cleared and eventually the IRQ line will be killed by interrupt subsystem. Some controllers have non-standard mechanism to indicate IRQ pending so that this condition can be detected and worked around. This patch adds an optional operation ->sff_irq_check() which will be called for each port from the ata_sff_interrupt() if an unexpected interrupt is received. If the operation returns %true, ->sff_check_status() and ->sff_irq_clear() will be cleared for the port. Note that this doesn't mark the interrupt as handled so it won't prevent IRQ subsystem from killing the IRQ if this mechanism fails to clear the spurious IRQ. This patch also implements ->sff_irq_check() for ata_piix. Note that this adds slight overhead to shared IRQ operation as IRQs which are destined for other controllers will trigger extra register accesses to check whether IDE interrupt is pending but this solves rare screaming IRQ cases and for some curious reason also helps weird BIOS related glitch on Samsung n130 as reported in bko#14314. http://bugzilla.kernel.org/show_bug.cgi?id=14314 * piix_base_ops dropped as suggested by Sergei. * Spurious IRQ detection doesn't kick in anymore if polling qc is in progress. This provides less protection but some controllers have possible data corruption issues if the wrong register is accessed while a command is in progress.

ata_piix: parallel scanning on PATA needs an extra locking Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers.

ata_piix: add workaround for Samsung DB-P70 Samsung DB-P70 somehow botched the first ICH9 SATA port. The board doesn't expose the first port but somehow SStatus reports link online while failing SRST protocol leading to repeated probe failures and thus long boot delay. Because the BIOS doesn't carry any identifying DMI information, the port can't be blacklisted safely. Fortunately, the controller does have subsystem vendor and ID set. It's unclear whether the subsystem IDs are used only for the board but it can be safely worked around by disabling SIDPR access and just using SRST works around the problem. Even when the workaround is triggered on an unaffected board the only side effect will be missing SCR access.

SATA PIIX: Blacklist system that spins off disks during ACPI power off Some notebooks from HP have the problem that their BIOSes attempt to spin down hard drives before entering ACPI system states S4 and S5. This leads to a yo-yo effect during system power-off shutdown and the last phase of hibernation when the disk is first spun down by the kernel and then almost immediately turned on and off by the BIOS. This, in turn, may result in shortening the disk's life times. To prevent this from happening we can blacklist the affected systems using DMI information.

This patch updates piix_broken_suspend() such that it can match such case. As the borked DMI data is a bit generic, matching many entries to make the match more specific is necessary.

ata_piix: fix macbook ich8m problems ICH8M on macbooks are peculiar in that some of them lock up when the second port is enabled, some return bogus values on SIDPR access while yet others hang on SIDPR access. Also, the ich8m_apple_sata entry was wrongly added below generic ich8m entry making it virtually useless. This patch works around macbook ich8m problems by * moving ich8m_apple_sata entry above generic ich8m entry * dropping PIIX_FLAG_SIDPR from ich8m_apple_sata * adding subsystem 106b:00a1 as ich8m_apple_sata Reported and tested by MATSUBAYASHI.

libata: implement and use sata_std_hardreset() Implement sata_std_hardreset(), which simply wraps around sata_link_hardreset(). sata_std_hardreset() becomes new standard hardreset method for sata_port_ops and sata_sff_hardreset() moves from ata_base_port_ops to ata_sff_port_ops, which is where it really belongs. ata_is_builtin_hardreset() is added so that both ata_std_error_handler() and ata_sff_error_handler() skip both builtin hardresets if SCR isn't accessible. piix_sidpr_hardreset() in ata_piix.c is identical to sata_std_hardreset() in functionality and got replaced with the standard function.

libata: move generic hardreset code from sata_sff_hardreset() to sata_link_hardreset() sata_sff_hardreset() contains link readiness wait logic which isn't SFF specific. Move that part into sata_link_hardreset(), which now takes two more parameters - @online and @check_ready. Both are optional. The former is out parameter for link onlineness after reset. The latter is used to wait for link readiness after hardreset. Users of sata_link_hardreset() is updated to use new funtionality and ahci_hardreset() is updated to use sata_link_hardreset() instead of sata_sff_hardreset(). This doesn't really cause any behavior change. Signed-off-by: Tejun Heo <htejun@gmail.com>

libata: rename SFF functions SFF functions have confusing names. Some have sff prefix, some have bmdma, some std, some pci and some none. Unify the naming by... * SFF functions which are common to both BMDMA and non-BMDMA are prefixed with ata_sff_. * SFF functions which are specific to BMDMA are prefixed with ata_bmdma_. * SFF functions which are specific to PCI but apply to both BMDMA and non-BMDMA are prefixed with ata_pci_sff_. * SFF functions which are specific to PCI and BMDMA are prefixed with ata_pci_bmdma_. * Drop generic prefixes from LLD specific routines. For example, bfin_std_dev_select -> bfin_dev_select. The following renames are noteworthy. ata_qc_issue_prot() -> ata_sff_qc_issue() ata_pci_default_filter() -> ata_bmdma_mode_filter() ata_dev_try_classify() -> ata_sff_dev_classify() This rename is in preparation of separating SFF support out of libata core layer.

libata: make reset related methods proper port operations Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.

libata: implement and use ops inheritance libata lets low level drivers build ata_port_operations table and register it with libata core layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This becomes worse for drivers which support related similar controllers which differ slightly. They share most of the operations except for a few. However, the driver still needs to list all operations for each variant. This results in large number of duplicate entries, which is not only inefficient but also error-prone as it becomes very difficult to tell what the actual differences are. This duplicate boilerplates all over the low level drivers also make updating the core layer exteremely difficult and error-prone. When compounded with multi-branched development model, it ends up accumulating inconsistencies over time. Some of those inconsistencies cause immediate problems and fixed. Others just remain there dormant making maintenance increasingly difficult. To rectify the problem, this patch implements ata_port_operations inheritance. To allow LLDs to easily re-use their own ops tables overriding only specific methods, this patch implements poor man's class inheritance. An ops table has ->inherits field which can be set to any ops table as long as it doesn't create a loop. When the host is started, the inheritance chain is followed and any operation which isn't specified is taken from the nearest ancestor which has it specified. This operation is called finalization and done only once per an ops table and the LLD doesn't have to do anything special about it other than making the ops table non-const such that libata can update it. libata provides four base ops tables lower drivers can inherit from - base, sata, pmp, sff and bmdma. To avoid overriding these ops accidentaly, these ops are declared const and LLDs should always inherit these instead of using them directly. After finalization, all the ops table are identical before and after the patch except for setting .irq_handler to ata_interrupt in drivers which didn't use to. The .irq_handler doesn't have any actual effect and the field will soon be removed by later patch. * sata_sx4 is still using old style EH and currently doesn't take advantage of ops inheritance.

libata: normalize port_info, port_operations and sht tables Over the time, port info, ops and sht structures developed quite a bit of inconsistencies. This patch updates drivers. * Enable/disable_pm callbacks added to all ahci ops tables. * Every driver for SFF controllers now uses ata_sff_port_start() instead of ata_port_start() unless the driver has custom implementation. * Every driver for SFF controllers now uses ata_pci_default_filter() unless the driver has custom implementation. * Removed an odd port_info->sht initialization from ata_piix.c. Likely a merge byproduct. * A port which has ATA_FLAG_SATA set doesn't need to set cable_detect to ata_cable_sata(). Remove it from via and mv port ops. * Some drivers had unnecessary .max_sectors initialization which is ignored and was missing .slave_destroy callback. Fixed. * Removed unnecessary sht initializations port_info's. * Removed onsolete scsi device suspend/resume callbacks from pata_bf54x. * No reason to set ata_pci_default_filter() and bmdma functions for PIO-only drivers. Remove those callbacks and replace ata_bmdma_irq_clear with ata_noop_irq_clear. * pata_platform sets port_start to ata_dummy_ret0. port_start can just be set to NULL. * sata_fsl supports NCQ but was missing qc_defer.

PM: Introduce PM_EVENT_HIBERNATE callback state During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

ata_piix: implement SIDPR SCR access For ICH8, SCRs can be accessed using index and data register pair located at BAR 5. This patch implements support for it such that PHY status, errors and hardreset are available for those controllers. This is the only case where two devices on a PATA channel have access to SCRs and creates a unique problem of mapping two SCRs to one link. Note that this is different from PMP case in that they aren't quite separate links - e.g. softreset resets both devices. This problem is worked around by merging the SCR values. To upper layer, it looks like there is a single link with one set of SCRs but with two devices. This works well enough for PHY event, error reporting and hardreset. Supporting hardreset is important because in rare cases SATA devices fail to recover without it after PHY errors.

ata_piix: disallow UDMA 133 on ICH5 & ICH7 There is another outstanding issue with ata_piix.c. Intel has never officially supported anything faster than PATA 100MB/s. But, the ata_piix.c driver "define" the ICH5 & ICH7 as UDMA6 (aka 133MB/s) capable. [ Well, no one has probably noticed it before, because there is bug in do_pata_set_dmamode... Just look at libata_atapiix_enable_real_udma133.patch and you'll see what wrong with it. ] Here are Intel's datasheets for the affected chipsets: ICH5 Datasheet: http://www.intel.com/design/chipsets/datashts/252516.htm (See note on page 183: "... the ICH5 supports reads at the maximum rate of 100MB/s.") ICH7 Datasheet: http://www.intel.com/design/chipsets/datashts/307013.htm (See first note on page 190: "... the ICH7 supports reads at the maximum rate of 100MB/s.") They are two different ways to deal with it: - Either - 1. replace all ich_pata_133 with ich_pata_100. (libata_atapiix_disable_udma6.diff - diff from 2.6.22 ) - Or - 2. keep all ich_pata_133 and fix the bug in "do_pata_set_dmamode". (libata_atapiix_enable_real_udma133.patch - diff from 2.6.22) If there are any concerns about the safety of the patch patch: http://lkml.org/lkml/2007/7/6/292 (It was already tested by an Intel employee, but I guess a bit more user input is necessary here... ) This patch implements 1.

drivers/firmware: const-ify DMI API and internals Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

This patch uses DMI to match those machines and bypass device disable on those machines during suspend. As the device needs to be put into enabled state on resume without affecting PCI enable count, matching resume callback uses __pci_reenable_device().

PCI: Change all drivers to use pci_device->revision Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

libata: clean up SFF init mess The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers. It's simple enough. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

libata: add deadline support to prereset and reset methods Add @deadline to prereset and reset methods and make them honor it. ata_wait_ready() which directly takes @deadline is implemented to be used as the wait function. This patch is in preparation for EH timing improvements. * ata_wait_ready() never does busy sleep. It's only used from EH and no wait in EH is that urgent. This function also prints 'be patient' message automatically after 5 secs of waiting if more than 3 secs is remaining till deadline. * ata_bus_post_reset() now fails with error code if any of its wait fails. This is important because earlier reset tries will have shorter timeout than the spec requires. If a device fails to respond before the short timeout, reset should be retried with longer timeout rather than silently ignoring the device. There are three behavior differences. 1. Timeout is applied to both devices at once, not separately. This is more consistent with what the spec says. 2. When a device passes devchk but fails to become ready before deadline. Previouly, post_reset would just succeed and let device classification remove the device. New code fails the reset thus causing reset retry. After a few times, EH will give up disabling the port. 3. When slave device passes devchk but fails to become accessible (TF-wise) after reset. Original code disables dev1 after 30s timeout and continues as if the device doesn't exist, while the patched code fails reset. When this happens, new code fails reset on whole port rather than proceeding with only the primary device. If the failing device is suffering transient problems, new code retries reset which is a better behavior. If the failing device is actually broken, the net effect is identical to it, but not to the other device sharing the channel. In the previous code, reset would have succeeded after 30s thus detecting the working one. In the new code, reset fails and whole port gets disabled. IMO, it's a pathological case anyway (broken device sharing bus with working one) and doesn't really matter. * ata_bus_softreset() is changed to return error code from ata_bus_post_reset(). It used to return 0 unconditionally. * Spin up waiting is to be removed and not converted to honor deadline. * To be on the safe side, deadline is set to 40s for the time being.

libata: update libata LLDs to use devres Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

[PATCH] ata_piix: use piix_host_stop() in ich_pata_ops piix_init_one() allocates host private data which should be freed by piix_host_stop(). ich_pata_ops wasn't converted to piix_host_stop() while merging, leaking 4 bytes on driver detach. Fix it. This was spotted using Kmemleak by Catalin Marinas. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Catalin Marinas <catalin.marinas@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] libata: always use polling IDENTIFY libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was introduced. This has caused a lot of problems including device misdetection and phantom device. ATA_FLAG_DETECT_POLLING was added recently to selectively use polling IDENTIFY on problemetic drivers but many controllers and devices are affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING for each such case is diffcult and not very rewarding. This patch makes libata always use polling IDENTIFY. This is consistent with libata's original behavior and drivers/ide's behavior.

[PATCH] ata_piix: strip now unneded MAP related stuff Now that PCS isn't used for device detection anymore... * esb_sata is identical to ich5_sata * no reason to know present_shift * no reason to store map_db in host private area The MAP table itself is left because it can be used for SCR access.

[PATCH] ata_piix: apply device detection via polling IDENTIFY PATA PIIX uses reset signature + TF r/w test for device presence detection, which doesn't always work. It sometimes reports phantom device which results in IDENTIFY timeouts. SATA PIIX uses some combination of PCS + reset signature + TF r/w test for device presence detection. No combination satifies all and for some controllers, there doesn't seem to be any combination which works reliably. This patch makes both PATA and SATA piix's use reset signature + TF r/w + polling IDENTIFY for device detection. This is what the old libata (before irq-pio and new EH) did and what IDE does. This patch also removes now obsolete PIIX_FLAG_IGNORE_PCS, force_pcs and related code. Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] ata_piix: allow 01b MAP for both ICH6M and ICH7M ICH7M was separated from ICH6M to allow undocumented MAP value 01b which was spotted on an ASUS notebook. However, there is also notebooks with MAP value 01b on ICH6M. This patch re-merges ICH6M and ICH7M entries and allows MAP value 01b for both. This problem has been reported and initial patch provided by Jonathan Dieter.

[PATCH] libata: use correct map_db values for ICH8 Use valid values for ICH8 map_db. With the old values, when the controller was in Native mode, and SCC was 1 (drives configured for IDE), any drive plugged into a slave port was not recognized. For Combined Mode (and SCC is still 1), 2 is a value value for MAP.map_value, and needs to be recognized.

[PATCH] libata-eh: Remove layering violation and duplication when handling absent ports This removes the layering violation where drivers have to fiddle directly with EH flags. Instead we now recognize -ENOENT means "no port" and do the handling in the core code. This also removes an instance of a call to disable the port, and an identical printk from each driver doing this. Even better - future rule changes will be in one place only.

libata: Grand renaming. The biggest change is that ata_host_set is renamed to ata_host. * ata_host_set => ata_host * ata_probe_ent->host_flags => ata_probe_ent->port_flags * ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags * ata_host_stats => ata_port_stats * ata_port->host => ata_port->scsi_host * ata_port->host_set => ata_port->host * ata_port_info->host_flags => ata_port_info->flags * ata_(.*)host_set(.*)\(\) => ata_\1host\2() The leading underscore in ata_probe_ent->_host_flags is to avoid reusing ->host_flags for different purpose. Currently, the only user of the field is libata-bmdma.c and probe_ent itself is scheduled to be removed. ata_port->host is reused for different purpose but this field is used inside libata core proper and of different type.
