    drm/radeon/kms: add missing Evergreen texture formats to the CS parser

    BC6 and BC7 are described in ARB_texture_compression_bptc.

    No idea what FMT_32_AS_32_32_32_32 is good for.

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

It looks like the commit you bisected to was the one which fixed this problem,
not the one that caused the black screen.

You should probably ignore X for the bisect, and just call any kernel that
lights up the monitor good, otherwise bad.

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
