[PATCH 0/2] drm/radeon/kms: tex3D mipmap fix & R500 VAP regs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi devs,

The first attached patch fixes the calculation of mipmapped 3D texture sizes
in the CS checker, the 3rd dimension (depth) should be minified too. This
should probably go to 2.6.34.

The second patch adds 2 new regs:
- VAP_ALT_NUM_VERTICES, along with an update to the CS checker.
- VAP_INDEX_OFFSET, I don't think this one needs to be tracked, because we
have min/max vertex index clamping, but I might be wrong.

Both probably need a DRM version bump so that I can detect them in
userspace.

Please review.

-Marek
