why isn't udev picking up the GPU? and setting
xf86_num_platform_devices to 1 is the question you need to answer
pci probing isn't really something we should be relying on.
You may be tired of me answering again and again in same thread but I
may found issue (or be wrong again).
platformProbe() grabs drm/card0 as it should. There are entries in
x86_platform_devices as they should be.
But platform_find_pci_info() checks pci_device_is_boot_vga() and if it
is then primaryBus is set to BUS_PLATFORM.
But my AArch64 lacks boot graphics support in firmware so boot_vga is
set to 0 for pcie card:
14:25 hrw@pinkiepie-rawhide:0000:01:00.0$ pwd
/sys/devices/platform/soc/1f2b0000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0
14:25 hrw@pinkiepie-rawhide:0000:01:00.0$ cat boot_vga 0
If I kill that check then Xserver starts.
