Yes, it helped, thank you very much.
The compressed Xorg.0.log is attached as proof.

To others: the patch is against xf86-video-ati.

Two notes, though:

1. Is it normal that "xrandr --listproviders" lists 3 providers?

[zozo at localhost ~]$ cat xrandr-providers
Providers: number : 3
Provider 0: id: 0x86 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload 
crtcs: 4 outputs: 3 associated providers: 2 name:radeon
Provider 1: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload 
crtcs: 0 outputs: 0 associated providers: 2 name:radeon
Provider 2: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload 
crtcs: 0 outputs: 0 associated providers: 2 name:radeon

2. I tried glxgears with and without DRI_PRIME=1 as below:

[zozo at localhost ~]$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
299 frames in 5.0 seconds = 59.558 FPS
[zozo at localhost ~]$ DRI_PRIME=1 glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
5589 frames in 5.0 seconds = 1117.730 FPS
5369 frames in 5.0 seconds = 1073.715 FPS
5699 frames in 5.0 seconds = 1139.670 FPS

Obviously, it doesn't sync to the framerate with PRIME.
On the other hand, nothing is displayed in the glxgears window.
I have llvm 3.4-4 and Mesa 10.1-rc1 from Fedora 21 rawhide.

I will go back to plain Fedora 20 (Xorg 1.14, llvm 3.3 and Mesa 9.2.5)
and try the same patch to see if there's any difference.

Best regards,
Zoltán Böszörményi
