- Define a device call for PCI bus instances to fetch a direct child's
device handle given the device's device/function #s (extracted from
a pcitag_t). Use it to associate the handle with the child device
at config_found() time.
- Implement this device call for ACPI and OpenFirmware.
- Enable the OpenFirmware variant for evbarm FDT, macppc, ofppc, sparc64.
- Obsolete acpi_device_register(); it is no longer needed.
- Obsolete setting the OpenFirmware handle in PCI devices in the
sparc64 device_register(); it is no longer needed.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Since files.wscons et al. are included by ~all ports anyway, include

These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Adjust assembler in_cksum code to new signature and re-enable it.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Add MODULAR option. Include kernel linker stuff if MODULAR.

Initial support for floppy drives on sparc64. This has been tested
on an Ultra 2 and works fine, apart from formatting which is known
to be broken. It failed to work on an ebus machine. The ebus

Commit changes proposed on tech-kern Thu, 6 Nov 2003
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).

Make the clock device aldo depend on mc146818, to make kernels without
the 'rtc at ebus' driver configured (e.g. for sbus machines) link.

- Adapt to MI mk48txx(4) changes.
- Switch rtc (M5819) routines to use MI mc146818(4) driver.

Tested on Ultra5 (mkclock_ebus), but mkclock_sbus and rtc_ebus are not tested.

Connect the front panel power button on psycho based machines to sysmon's
/dev/power.

XXX - due to the way interrupt handling is structured we have no easy
way to defer clearing the button interrupt until the sysmon callback
has happened and the event is dispatched. We clear it imediately on
return from the interrupt handler. This means we get an interrupt storm
until the button is released, and then start to handle it.
This needs to be fixed! (But with the default application for the power
button does not make a user visible difference.)

PCI-CardBus bridge support for sparc64:
- add CardBus and PCMCIA devices configrations.
- add workaround for internal compiler error on dev/ic/elink3.c.

misc tidiness.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Fix the sparc64 console.

Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them. So, here we go:

Add a new PROM console driver with a major number and everything.
This is the default driver if nothing else attaches. It does not
use the keyboard driver since the PROM translates keystrokes itself.
(Unfortunately it also swallows L1-A).

Have the keyboard driver take over the console when it attaches on a
serial port. When a serial port detects a keyboard and attaches the
keyboard driver, it needs to provide a set of consdev vectors. They
keyboard driver will use those to send I/O to the keyboard and mouse.

whole bunch of changes:
- merge IOMMU DVMA code from sbus/psycho into iommu.c. this code was
identical and a few minor inconsistencies had crept in. this way
keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
files. same with ebus/ebus_bus.c. delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.

- auxio cleanup and sbus support.
- make GENERIC64 include GENERIC and set the 3 optoins it needs. suggested
by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Adjust assembler in_cksum code to new signature and re-enable it.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Add MODULAR option. Include kernel linker stuff if MODULAR.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in

interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Initial support for floppy drives on sparc64. This has been tested
on an Ultra 2 and works fine, apart from formatting which is known
to be broken. It failed to work on an ebus machine. The ebus

to do the sbus and ebus attachments, along with help from martin@

Commit changes proposed on tech-kern Thu, 6 Nov 2003
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).

Make the clock device aldo depend on mc146818, to make kernels without
the 'rtc at ebus' driver configured (e.g. for sbus machines) link.

- Adapt to MI mk48txx(4) changes.
- Switch rtc (M5819) routines to use MI mc146818(4) driver.

Tested on Ultra5 (mkclock_ebus), but mkclock_sbus and rtc_ebus are not tested.

XXX This file should be split into each device and each bus attachment,

Connect the front panel power button on psycho based machines to sysmon's
/dev/power.

XXX - due to the way interrupt handling is structured we have no easy
way to defer clearing the button interrupt until the sysmon callback
has happened and the event is dispatched. We clear it imediately on
return from the interrupt handler. This means we get an interrupt storm
until the button is released, and then start to handle it.
This needs to be fixed! (But with the default application for the power
button does not make a user visible difference.)

PCI-CardBus bridge support for sparc64:
- add CardBus and PCMCIA devices configrations.
- add workaround for internal compiler error on dev/ic/elink3.c.

Switch to use cycle counter (%tick) based microtime().

This is derived from alpha/microtime.c and i386/tsc_microtime.c,

now that mem_no is emitted by config(8), there is no reason to keep

misc tidiness.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Enable sab.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Add a flag for ofpci to let psycho chose between pci and ofpci.

Fix the sparc64 console.

Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them. So, here we go:

Add a new PROM console driver with a major number and everything.
This is the default driver if nothing else attaches. It does not
use the keyboard driver since the PROM translates keystrokes itself.
(Unfortunately it also swallows L1-A).

Have the keyboard driver take over the console when it attaches on a
serial port. When a serial port detects a keyboard and attaches the
keyboard driver, it needs to provide a set of consdev vectors. They
keyboard driver will use those to send I/O to the keyboard and mouse.

whole bunch of changes:
- merge IOMMU DVMA code from sbus/psycho into iommu.c. this code was
identical and a few minor inconsistencies had crept in. this way
keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
files. same with ebus/ebus_bus.c. delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.

- auxio cleanup and sbus support.
- make GENERIC64 include GENERIC and set the 3 optoins it needs. suggested
by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed

also include some work-in-progress #if 0'ed code to do the same for the
dcache_flush*() functions.


(some of these could probably move into the cpuinfo except that sparc64
systems don't really ever work with mismatches AFAICT.)

branches: 1.130.2;
Add EDID and video mode setting support to FFB.

Add definitions for registers related to video modes, and to DDC. Rename
other registers to be more descriptive.
Add i2c bus routines to read the EDID data via DDC.
Add routines to calculate, and to set, the video mode.

Note, that interlaced and stereo video modes are not supported.

Thanks to Michael Lorenz and Jared McNeill for advice and encouragement,
and to Martin Husemann for testing.

add pci@pryo@mainbus and ebus@mainbus support.

branches: 1.128.2;
defflag some flags for the ffb driver

branches: 1.127.2;
move the memcpy/memset implementations out into their own file, with the
block copy versions as well. move some of the definitions in locore.s
into a new locore.h.

locore.s is almost 2000 lines shorter with this change.

Make kernel buildable without device ecadc.

Remove the envctrl driver, it is superseeded by the more general pcfiic @
ebus. Add the SB1000/SB2000 fan controll driver (tda). From OpenBSD.
Move config files over to direct configuration of i2c devices.

move {dump,print}_[id]tlb() into a separate file.

branches: 1.123.2;
Import support for upa64s device (/upa on SB1000/2000) from OpenBSD.
Attach ffb both at mainbus and at upa.

add gfb at mainbus

Port lom(4) driver for LOMlite lights out management hardware monitor
and watchdog timer from OpenBSD.

It supports the LOMlite found on Sun Netra t1 and the LOMlite2 found
on Sun Netra T1/X1 and Sun Fire V100/V120.

checkpoint my work-in-progress port of this driver.
it boots some way but will crash attaching rtc0.

known TODO items:
- figure out why BUS_SPACE_MAP_LINEAR mappings generate data errors
(cause of the rtc issue)
- several interrupt issues

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Adjust assembler in_cksum code to new signature and re-enable it.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Add MODULAR option. Include kernel linker stuff if MODULAR.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Add envctrl(4): Sun Ultra Enterprise 450 environmental monitoring driver.
Also add accompanying i2c controller driver, pcf8584.
Both written by me. Some cosmetic improvements from Iain Hibbert.

More cleanup of sparc64 clock stuff:
- split mkclock attachment from sparc64/clock.c into dev/mkclock.c
(now clock.s only contains clock interrupt and timecounter stuff)
- rename match/attach functions of rtc at ebus to match the device name
- update some comments around clock devices in GENERIC

No objection on port-sparc64 for a month.

Remove eeprom and clock at mainbus stuff.
They are available only on sun4 or sun4c.

avoid bringing in mc146818 routines for kernels that do not have the
'rtc'-style clock linked in. put the rtc code in it's own file and
only link it in if it is actually configured. fixes PR#23342.

Initial support for floppy drives on sparc64. This has been tested
on an Ultra 2 and works fine, apart from formatting which is known
to be broken. It failed to work on an ebus machine. The ebus
support compiles fine, but I don't have hardware for testing. This
code is based on the sparc driver with hints from OpenBSD on how
to do the sbus and ebus attachments, along with help from martin@
and mrg@.

Initial commit approved by martin@

TODO:
- fix ebus support
- fix XXX issues
- check resource deallocation
- fix formatting
- merge remaining differences from sparc driver
- split out back end chip support
- have sparc driver use new common back end chip support
- adapt to newlock when branch is ready
- adapt to "disk-info" property dictionary

branches: 1.103.2;
Vcons-ify the ffb driver, from macallan.
Also adds some redrawing when entering DDB.

add bluetooth support to sparc64, built by default in GENERIC

branches: 1.101.4;
New psm driver for use on Ultrabook IIi. Right now it supports the power
button and lid switch. I will add environmentals (battery, etc.) later.

branches: 1.100.2;
convert to timecounters (from branch simonb-timecounters)

branches: 1.99.2;
Convert existing ath users to new Makefile, except for amd64, which needs
the rules due to needing to conditionally postprocess the HAL object file.

Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.

branches: 1.98.2; 1.98.4; 1.98.6;
Add glue to make ath* usable on sparc64.

do not include "compat/aout/files.aout", COMPAT_AOUT is soon to be removed

nothing attaches to a "sabtty", so there is no need for an
interface attribute

Realy disable optimization for 32bit kernels when compiling uvm_bio.c.

Reach over to the sparc openfirm & openprom implementation.

Add sparc/sparc/promlib.c.

checkpoint of MP work from dennis and myself. includes cross-processor
interrupt framework, a sledgehammer TLB invalidation and misc MP fixes.
doesn't work at all yet.

whitespace police

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

Commit changes proposed on tech-kern Thu, 6 Nov 2003
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).

Make the clock device aldo depend on mc146818, to make kernels without
the 'rtc at ebus' driver configured (e.g. for sbus machines) link.

- Adapt to MI mk48txx(4) changes.
- Switch rtc (M5819) routines to use MI mc146818(4) driver.

Tested on Ultra5 (mkclock_ebus), but mkclock_sbus and rtc_ebus are not tested.

XXX This file should be split into each device and each bus attachment,
XXX and moved into sys/arch/sparc64/dev or sys/dev/sun.

Don't attach zs at mainbus.

Add compat_16_machdep.c

Remove workarounds for bugs in the old compiler.

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

Driver for CP1500/1400 watchdog timer.
