--- Comment #4 from Vladi vladi@aresgate.net 2012-02-26 17:39:33 PST --- the commit i got from git bisect was deduced from an working Xorg setup. There was an point where the KMS was working but Xorg was not untill the the commit i mentioned. The errors in dmesg while KMS was fine and Xorg still not working were: [ 88.579198] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! [ 88.579733] radeon 0000:01:05.0: r600_check_texture_resource:1338 texture invalid format 26

BC6 and BC7 are described in ARB_texture_compression_bptc.

Can it be related to this bug? https://bugs.freedesktop.org/show_bug.cgi?id=41569

If yes - it's fixed in latest kernels (somewhere near 3.2.5 - I'm not sure)

drm/radeon/kms: disable hdmi audio by default

The current RE'd code causes blank screens and display problems on a lot of systems. So disable it by default for now. It can still be enabled by setting the audio parameter to 1. E.g.: radeon.audio=1

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=38010 https://bugs.freedesktop.org/show_bug.cgi?id=27731 https://bugs.freedesktop.org/show_bug.cgi?id=35970 https://bugs.freedesktop.org/show_bug.cgi?id=26195 and many other reported problems.
