kms tiling disabled

[agd5f]

It defaults off?

Yes. Tiling is off by default on r6xx+ as the kernel support is not in a formal release yet and there are probably a few bugs left to be shaken out.

Right, I guess I'll switch it back off, Trying to debug whether r600c actually handles GL_LEQUAL, GL_LESS, GL_GEQUAL, and GL_GREATER wrong or if it's just the tiling.

Ps. yes, they are. The effect is just worse with tiling on. Seeable in shadowtex.

[agd5f]

shadowtex is busted in r600c due to depth buffers needing to be decompressed before being used as a texture source. It should work in r600g.

[nanonyme]

Yeah, it's at the very least consistent in r600g. Not sure about right. Would need a better reference point than the ones I have atm.

[agd5f]

For D24 or D24S8 formats, you need to do a Z to CB decompress blit. In place decompression only works for D16 or D32 formats.

You need the xorg option to enable tiling for r6xx+. Also there's a bug in the current kernel that got added when hiz support was added. It's fixed in this patch:

http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=b824b364d9ee001fc8c6bb71cc49f19bf740dd99

which will make it's way upstream soon.

thx for the info, you know if this patch made it to 2.6.36-rc2/3 kernels??

[agd5f]

It should be in rc3.
