Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
One additional observation that I just made is that on GK208, the blob
apparently doesn't use the result of S2R Rx, SR_INVOCATION_ID
wholesale in TCS. It either passes it through a I2I.S32.S32 Rx, |Rx|
(i.e. absolute value), or even more paradoxically, shl 2; shr 2; which
removes the top *2* bits, rather than just the top 1. However I see no
such behaviour on GF108.
I'm going to test out

Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
Hello,
I've been debugging a few different tessellation shader issues with
nouveau, but let's start small. I see this issue on my GK208 with high
frequency, and I *think* I've seen it once or twice on my GF108, but
it's exceedingly rare, if it does happen. I don't have a GK10x to test
on, unfortunately, but I assume it'll have the same issue as the
GK208.
The issue is

[PATCH 1/2] nvc0/ir: detect AND/SHR pairs and convert into EXTBF
Some shaders appear to extract bits using shift/and combos. Detect
(some) of those and convert to EXTBF instead.

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
