Most of the driver enumeration functions take an array and a maximum
number of entries that they are allowed to fill in. Upon success, they
return the number of entries filled in. This allows them to be easily
used to consecutively.
One exception is the xf86MatchDriverFromFiles() function, which doesn't
return a value, so callers have to manually search the array for the
first empty entry.
This commit modifies the xf86MatchDriverFromFiles() to behave the same
way as others, which makes it easier to deal with.

On UEFI machines you'd prefer fbdev to grab efifb instead of vesa trying
to initialize and failing in a way we can't unwind from. On BIOS
machines this is harmless: either there is an fbdev driver and it'll
probably be more capable, or there's not and vesa will kick in anyway.

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.

January, I've added a few indent flags:
-bap

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`

Currently there is a single file, xorg.conf, for configuring the server.
This works fine most of the time, but it becomes a problem when packages
or system services need to adjust the configuration. Instead, allow
multiple configuration files to live in a directory. Typically this will
be /etc/X11/xorg.conf.d.
Files with a suffix of .conf will be read and added to the server
configuration after xorg.conf. The server won't fall back to using the
auto configuration unless there is no config file and there are no files
in the config directory.
Right now this uses a simpler search template than the config file
search path by not using the command line or environment variable
parameters. The matching code was refactored a bit to make this more
coherent. Any DDX wanting to read the config files will need to call
xf86initConfigFiles before opening/reading them. This is to allow
xf86openConfigFile without xf86openConfigDirFiles and vice-versa.

In practice, some of the native drivers for older Geode products
have become deprecated due to lack of e.g. libpciaccess upgrade,
but that's OK, since most distributions don't ship them anymore.
In that case, we'll let X server fall back to good old VESA.
commit 48ee555833 (OpenSolaris VT support)
broke the autoconfiguration code in xf86AutoConfig.c that uses the
Solaris-specific VIS_GETIDENTIFIER ioctl on a frame buffer device like
/dev/fb by changing xf86Info.consoleFd from /dev/fb to a /dev/vt/*
device.
This fixes it by reworking the code to split the console device
(/dev/vt/*, the vtXX CLI option) from the frame buffer device
(/dev/fb, -dev option) to allow both VT and autoconfig to work.
It also fixes the console device to use /dev/fb when VT's are not
supported instead of throwing a Fatal Error because it can't open
/dev/vt/0.

- Allow returning multiple drivers to try for a given PCI id (for instance,
try "geode" then "amd" for AMD Geode hardware)
- On Solaris, use VIS_GETIDENTIFIER ioctl as well as PCI id to choose drivers
- Use wsfb instead of fbdev as a fallback on non-Linux SPARC platforms
