On Linux in order for future hotplug work, we are required to interface
to udev to detect device creation/removal. In order to try and get
some earlier testing on this, this patch adds the ability to use
udev for device enumeration on Linux.
At startup the list of drm/kms devices is probed and this info is
used to load drivers.
A new driver probing method is introduced that passes the udev
device info to the driver for probing.
The probing integrates with the pci probing code and will fallback
to the pci probe and old school probe functions in turn.
The flags parameter to the probe function will be used later
to provide hotplug and gpu screen flags for the driver to behave
in a different way.
This patch changes the driver ABI, all drivers should at least
be set with a NULL udev probe function after this commit.
v2: rename to platform bus, now with 100% less udev specific,
this version passes config_odev_attribs around which are an array
of id/string pairs, then the udev code can attach the set of attribs
it understands, the OS specific code can attach its attrib, and then
the core/drivers can lookup the required attribs.
also add MATCH_PCI_DEVICES macro.
This version is mainly to address concerns raised by ajax.
v3: Address comments from Peter.
fix whitespace that snuck in.
rework to use a linked list with some core functions that
xf86 wraps.
v4: add free list, fix struct whitespace.
ajax this address most of your issues?
v5: drop probe ifdef, fix logic issue
v6: some overhaul after more testing.
Implement primaryBus for platform devices.
document hotplug.h dev attribs - drop sysname attrib
fix build with udev kms disabled
make probing work like the PCI probe code,
match against bus id if one exists, or primary device.
RFC: add new bus id support "PLAT:syspath". we probably
want to match on this a bit different, or use a different
property maybe. I was mainly wanting this for use with
specifying usb devices in xorg.conf directly, but PLAT:path
could also work I suppose.
v6.1: add missing noop platform function
v7: fix two interactions with pci probing and slot claiming, prevents
pci and platform trying to load two drivers for same slot.
v8: test with zaphod mode on -ati driver, fixup resulting issue
clean up common probe code into another function, change busid
matching to allow dropping end of strings.
v9: fix platform probing logic so it actually works.
v9.1: fix pdev init to NULL properly.
v10: address most of Keith's concerns.

This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:
-bap
-psl
-T PrivatePtr
-T pmWait
-T _XFUNCPROTOBEGIN
-T _XFUNCPROTOEND
-T _X_EXPORT
The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:
dir1=$1
dir2=$2
for dir in $dir1 $dir2; do
(cd $dir && find . -name '*.o' | while read file; do
dir=`dirname $file`
base=`basename $file .o`
dump=$dir/$base.dump
objdump -d $file > $dump
done)
done
find $dir1 -name '*.dump' | while read dump; do
otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
diff -u $dump $otherdump
done

This patch makes xf86Configure.c free of PCI and SBUS code, moving to a more
meaningful location.

The move of the PCI device id probing into a separate file neglected to
return the number of found devices, and so the PCI devices were being
overwritten by the default entries for vesa and fbdev.

This patch creates the private xf86PciMatchDriver hook, which goes inside pci
code to match the drivers found in the system.
Now there's no direct references to PCI inside xf86AutoConfig.c anymore.

All functions that touch PCI and BUS were moved to their own files, organizing
the mess inside the InitOutput. Now, inside InitOutput, mostly accesses to
buses are coordinated by the new xf86BusConfig.
Two PCI probe functions just changed the name and a procedure to receive the
isolate devices parameters was created also, named xf86PciIsolateDevice.

This changes the ABI, but since the video ABI is at 6 already
it should be fine.
