Description Pavel Ondračka 2013-02-08 16:49:24 UTC 
All object in the 3.0 Heaven version are completely black... this seems to be the cause:
r300 FP: Compiler Error:
Rewrite of inst 4 failed Can't allocate source for Inst 36 src_type=1 new_index=1 new_mask=4
Using a dummy shader instead.

Full RADEON_DEBUG=fp log attached.

This may be a hardware limitation, however Heaven 2.1 version works fine, so maybe just a bug in the shader compiler.

Can you post the RADEON_DEBUG=fp dump with the patch applied?

Ok, maybe I made a mistake posting the patch:  Can you apply all six patches from:http://lists.freedesktop.org/archives/mesa-dev/2013-February/034357.html

After you apply the patches, run make check from src/gallium/drivers/r300 and make sure it passes and then re-test Heaven.

OK, with whole patch series applied the tests passes, however Heaven is still black.

Yes, this one fixes it.
Comment 13 Pavel Ondračka 2013-03-20 20:56:38 UTC 
BTW i did a quick tests piglit run with your patch on my RV530 with no regressions (no fixes either except 2 tests in EXT_framebuffer_multisample group, however those seems to be fairly random... )
Comment 14 Tom Stellard 2013-04-12 16:43:53 UTC 
Fixed in commit c6a86fb5639977f37a1403012669cdee86bbd89f

Thanks for your help with testing!
