Description Gordon Jin 2010-09-14 23:46:41 UTC 
This is forked from bug#29631, and intends to focus on the tiling issue.

Sandybridge D0 (pci id = 0126).

kernel 2.6.36-rc4, 2.6.35.

Good catch! But I'm pretty sure that fence reg only changed on sandybridge, but not for ironlake. So you should use IS_GEN6(dev) instead of HAS_PCH_SPLIT().

Please send this to intel-gfx list and cc stable.

thanks.

Thanks. And here is the new patch.

Ummm, I can't reproduce this problem now, with 2.6.34-rc6, even without your patch. I'd suggest just commit it since it works on your machine.

Applied to -fixes, will send pull request to Linus after I have had a chance to boot test [on pre-Sandybridge].
