Hi,

I recently purchased a Radeon HD 7850 for a desktop. However, despite my best efforts I've been unable to enable hardware acceleration for it. I have tried both radeon and radeonsi without any progress.

Here are the relevant logs:

dmesg|wgetpaste

lspci -kkk|wgetpaste

wgetpaste /var/log/Xorg.0.log
Your paste can be seen here: http://bpaste.net/show/92805/
emerge --info|wgetpaste
Your paste can be seen here: http://bpaste.net/show/92806/

Any help will be very appreciated

Code:
[    10.474] (II) RADEON(0): EXA: Driver will allow EXA pixmaps in VRAM
xf86-video-ati does not support EXA acceleration for radeonsi cards. You need to use glamor instead.

Even with glamor, I am unable to get direct acceleration to work

These are the logs with various versions of mesa/glamor/llvm

Code:
[    13.464] (EE) Failed to load /usr/lib64/xorg/modules/libglamoregl.so: /usr/lib64/xorg/modules/libglamoregl.so: undefined symbol: _glapi_tls_Context
This could be due to remants of a proprietary driver or problems with eselect opengl on your system.

glamor is for all radeons. Since Southern Islands, glamor is the only supported acceleration method. Earlier chipsets support EXA too.

So I have unmerged fglrx, anything else I can do to get rid of w/e is left behind?

Never mind, eselect opengl set xorg-x11 fixes the issues. I have direct acceleration working perfectly now :)
