Simplify and make extensible the config_search() / config_found() /

which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is

this is just a wrapper around config_match(), but that is an
implementation detail.)

- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

Apply a set of patches from Frank Wille to make the genfb attachment work
better on ofppc. In doing so, we also move a few functions around in
macppc and the generic ofw powerpc stuff to allow better sharing of code.
Also, introduce a model_init function.

move ofb_cons.c from macppc/dev to powerpc/oea and rename it to rascons.
This gets rid of some naming confusion, and makes it OFW-MI rather than
macppc specific.

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.

Support 48kHz by using aurateconv.
Based on a patch by TAMURA Kent -- thanks!

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.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Adapt to linux emul trap change.

For ports that wire up pciide in compatibility mode, have
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.

Ports that don't need to do this no longer need to supply a
dummy function.

Add AirMac frontend.

Add a gpio device to handle the gpio device & extint-gpio1
interrupt. (think ibook/powerbook)

Add devsw entries for "ld" (logical disks).

Added previously created files for powerpc Linux compatibility to the kernel
config system

Add machdep file for procfs. Currently only used for linux-style
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

back out my change powerpc/conf/files.ofw. Enable the inclusion of
dev/ofw/files.ofw on macppc. Add openfirm to ofppc/conf.c

Pull in dev/i2o/files.i2o.

defopt L2CR_CONFIG.

Add files.ieee1394

Switch to sys/dev/md_root.c. Tested on an INSTALL kernel.

Add (experimental) awacs audio driver. Output (play) only.

esp declaration was moved to conf/files.

Add the RAIDframe device major to the machine-dependent config files
so that the right entries get added to dev_name2blk[]. Needed for / on RAID.
(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

Add gmac. (commented out)

Use dev/rasops instead of dev/rcons.

* Split bandit and grackle.
* Add UniNorth support.

Now pcibus is attached like:
bandit0 at mainbus0
pci0 at bandit0 bus 0

This is the first check-in of CardBus driver. CardBus driver contains
CardBus bus stub, YENTA PCI-CardBus bridge (cbb), 3Com 3C575TX driver

media-bay CD support.

Add PowerBook LCD brightness and speaker volume button device.
Only brightness works for now.

Only declare block major numbers for devices which can be the root device.

Add a stub pciide_machdep_compat_intr_establish() for Power Macintosh.
Power Macintoshes with PCI IDE (e.g. the new Blue G3) don't have them
wired to compatibility mode, so just return a NULL cookie. We still have
to have this routine for the PCI IDE driver to link.

Split ADB driver to aed (ADB event device), akbd (ADB keyboard),
and ams (ADB mouse). adb is a bus now. (from Colin Wood)

We claim to support some mii-equiped pci ethernet drivers, so we
need to include dev/mii/files.mii. :-)

Ah, we use a _different_ ofcons; rename it macofcons to avoid the
name collision.

Add bus_dma support.

Add support for G3 Mac.

Add nvram device support.

Console support.

Add memory disk support.

Add support for UVM and MACHINE_NEW_NONCONTIG.

- 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.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

branches: 1.115.4;
add support for the onewire bus found in some macs, namely Quicksilver.
This can be used to read the EEPROM content from Apple Pro speakers, or to

the beginning of a driver for the 'Psoc' fan controller found in my 1GHz
TiBook. So far it does:
- initialize the fan controller via OF
- report temperatures to envsys
there is no documentation, only guesswork from looking at OF methods

With this my TiBook doesn't seem to overheat anymore.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c

- use shifted i2c addresses like everyone else
- use direct config
with this generic i2c drivers should work on the smu's i2c bus.

Remove support for macofcons(4), it's not actually possible to build a kernel
with it enabled - See PR port-macppc/53004 and it may have further problems even
so.
From <macallan>:
"There is some early console code that uses OF output but it causes problems
when we get close to MMU setup - I think it can go, it hasn't been enabled in
any config in at least a decade as far as I know."

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.

should be easy to fix.

Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

Apply a set of patches from Frank Wille to make the genfb attachment work
better on ofppc. In doing so, we also move a few functions around in
macppc and the generic ofw powerpc stuff to allow better sharing of code.
Also, introduce a model_init function.

move ofb_cons.c from macppc/dev to powerpc/oea and rename it to rascons.
This gets rid of some naming confusion, and makes it OFW-MI rather than
macppc specific.

have uninorth and bandit pull in their resp. IPI support stuff

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.
