Summary: r600g: Automatic mipmap generation doesn't work
properly
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: wielkiegie@gmail.com
Automatic mipmap generation using glGenerateMipmap (util_gen_mipmap) fills
mipmaps with wrong rendering. Piglit tests fbo-generatemipmap* are failing.
Software fallback works properly, as does llvmpipe.
Hardware:
rv670 (HD3870), amd64
Software:
kernel 2.6.38rc8, mesa from git, libdrm from git

Indeed it helps. Piglit test fbo-generatemipmap-formats is still failing, but
may be unrelated problem. Basic functionality now works properly.

Patch is strictly a work-around and a bloody hack (dripping even). Indicates
there's something should be happening in the driver code that isn't. "Fixes"
was a bad word choice.
Anyway, I can confirm this bug on RS880 (Radeon HD 4200).

This should be fixed by the following patches:

Still doesn't work on RS880 until it's added to the conditional on line 813 of
r600_hw_context.c
I wonder if this should apply to rv620, rv635 (and rs780?) also?

fixed in b9f2750900efb2667bc1dfc428b71d8a08b212be.
rv610/630/620/635 all work fine without the additional hack.
