xorg.conf snippet

Description of problem:

I have APM Mustang on my desk. As it has x8 pcie slot I connected Radeon HD5450 graphics card to it. But to get X11 running I need to have xorg.conf snippet (attached).

Version-Release number of selected component (if applicable):

xorg-x11-drv-ati-7.6.0-0.3.20150729git5510cd6.fc24.aarch64

How reproducible:

always

Steps to Reproduce:
1. grab apm mustang
2. connect radeon card
3. boot

Actual results:

Needs BusId snippet to get Xorg running.

Expected results:

Xorg runs without extra config.

Additional info:

I do not know is it driver or kernel fault.

Comment 5 Marcin Juszkiewicz 2015-08-25 19:05:16 UTC
When F23 installer boots it is not able to get graphical installer running due to this issue. But when I copy snippet from running system and then restart anaconda by hand - it runs nice local graphical installation.

Comment 6 Jérôme Glisse 2015-08-25 21:13:45 UTC
Probably the X server not trying to do PCIe enumeration on ARM. Just wild guess.

Comment 7 Marcin Juszkiewicz 2015-08-25 22:15:38 UTC
Xserver can do pci enumeration on AArch64 - it is just libpciaccess stuff.

The problem lies in other place - kernel/udev probably or xserver.

Configure sets CONFIG_UDEV_KMS variable and then XSERVER_PLATFORM_BUS is set as well. 

Then we have xf86BusProbe() function in hw/xfree86/common/xf86Bus.c (xserver source file). If XSERVER_PLATFORM_BUS is defined then xf86platformProbe() is called. And then it fails.

But if I disable that block then xf86PciProbe() is called and xserver finds PCIe card properly.

Comment 8 Marcin Juszkiewicz 2015-08-25 22:33:10 UTC

xserver hack

xf86platformProbe() calls config_odev_probe(xf86PlatformDeviceProbe) (argument is callback name)

xf86PlatformDeviceProbe() goes xf86_num_platform_devices times over xf86_platform_odev_attributes table to find /dev/dri/card0 entry.

The problem is that xf86_num_platform_devices == 0 so there is nothing to search for.

Comment 9 Marcin Juszkiewicz 2016-01-19 11:39:19 UTC
I discussed issue with several people and agreement was that this has to be done in kernel like it is on powerpc.

There will be patches sent to lkml once done.

Comment 10 Jeremy Linton 2016-08-02 18:18:10 UTC
Hi, I have a juno with the same card (HD5450), and a seattle with a x1300. I've been manually hacking my xorg as well. When you post the patch, please cc jeremy.linton. 

Thanks.

The v2 upstream series has been reviewed and tested; it should solve the issue:
