           Summary: xf86-video-ati git and drm-radeon-testing git: CS
                    checker leads mplayer / vlc to fail with xv
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: jb.faq at gmx.de


With xf86-video-ati git and Dave Airlieds drm-radeon-testing branch I get a
black or no image with some videos using mplayer (using xv and not gl). The cs
checker breaks it.

I can reproduce this problem with 1080p (not 720p) HD videos. This problem does
not appear with the 2.6.37 kernel.

This bug was introduced with 7ac3a2e0bcdadff7c7172a9f833f526b526da16b
(I bisected this)

I did the following:

commit 7ac3a2e0bcdadff7c7172a9f833f526b526da16b

    6xx+: switch to linear aligned rather than linear general

    linear aligned is supposedly more performant, but more
    importantly, linear general only works on the CB without
    slices.  The texture blocks technically don't support
    linear general although, I think linear general gets
    upgraded to linear aligned in the hw which is why it
    currently works.
