Subject: [PATCH xserver v2 5/7] xfree86: Remove redundant ServerIsNotSeat0
check from xf86CallDriverProbe
If foundScreen is TRUE, then all the code below the removed if
will not execute until we reach the return foundScreen; at the
end, so this entire if block is redundant.

Subject: [PATCH xserver v2 6/7] xfree86: Make adding unclaimed devices as GPU
devices a separate step
This is primarily a preparation patch for fixing the xserver exiting with
a "no screens found" error even though there are supported video cards,
due to the server not recognizing any card as the primary card.
This also fixes the (mostly theoretical) case of a platformBus capable
driver adding a device as GPUscreen before a driver which only supports
the old PCI probe method gets a chance to claim it as a normal screen.

Subject: [PATCH xserver v2 7/7] xfree86: Try harder to find atleast 1 non GPU
Screen
If we did not find any non GPU Screens, try again ignoring the notion
of any video devices being the primary device. This fixes Xorg exiting
with a "no screens found" error when using virtio-vga in a
virtual-machine and when using a device driven by simpledrm.
This is a somewhat ugly solution, but it is the best I can come up with
without major surgery to the bus and probe code.

Subject: [PATCH xserver 5/6] xfree86: Allow overriding primary GPU detection
from an OutputClass section
Allow using:
Option "PrimaryGPU" "yes"
In an OutputClass section to override the default primary GPU device
selection which selects the GPU used as output by the firmware.
If multiple output devices match an OutputClass section with
the PrimaryGPU option set, the first one enumerated becomes the
primary GPU.

Subject: [PATCH xserver 6/6] xfree86: Add ModulePath support for OutputClass
config Sections
Allow OutputClass config snippets to modify the module-path.
Note that any specified ModulePaths will be pre-pended to the normal
ModulePath. The idea behind this is that any output hardware specific
modules should have preference over the normal modules.
One use-case for this is the nvidia binary driver, this allows a
config snippet like this:
Section "OutputClass"
MatchDriver "nvidia"
Modulepath "/usr/lib64/nvidia/modules"
EndSection
To get the nvidia glx specific glx module loaded, but only when the
nvidia kernel driver is loaded.
Together with the glvnd work done recently, this allows the nouveau
+ mesa and nvidia-binary userspace stacks to co-exist on the same
system without any ldconfig / xorg.conf tweaking and the xserver will
automatically do the right thing depending on which kernel driver
(nouveau or nvidia) is loaded.
