           Summary: [RV740] Mipmapping broken in drm-radeon-next /
                    drm-next
           Product: DRI
           Version: DRI CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: liquid.acid@gmx.net


Hey there,

I already partially explained this in bug #31046.

With a recent drm-radeon-next or also drm-next the mipmaps are broken with both
r600c and r600g.

My hardware:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 4770 [RV740]

libdrm, xf86-video-ati and mesa are all git master tip.

Today I found some time to bisect drm-next and this commit introduces the
mipmap issue:
881fe6c1d06bf49f4ab7aef212cdaf66bd059614

drm/radeon/kms: properly compute group_size on 6xx/7xx

Needed for tiled surfaces.

-------------------------------

Link:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=881fe6c1d06bf49f4ab7aef212cdaf66bd059614

Looks like tiling_group_size has to be 256 on my hardware.

Greets,
Tobias

Fixed in mesa git master and 7.9.  Although, I'm not sure how best to handle
backwards compat for old userspace.

Thanks for fixing this. Although I noticed that your patch only seems to touch
r600 classic, while I also noticed lots of mipmap rendering errors with the
gallium driver. Or are the r600g issues a separate problem?

gallium needs to be updated as well, just haven't gotten a chance yet.

OK, no need to hurry. Was just curious and a bit surprised when the bug was
suddenly set to RESOLVED/FIXED.
