Indeed, this fixed the original issue on the GK208. Additionally it
seems like starting with GK104 the mechanism for indirect offsets for
ALD/AST changed and a AL2P instruction must now be used to determine
the indirect or physical offset. Once nouveau was adjusted to do
this, all
I think I figured out what was going on. Will re-check on the GK208,
but on a GF108 the random blue splotches in Unigine Heaven are gone
now. Turns out that with an instruction like
/*00d0*/ ALD.128 R0, a[0x70], R0;
/* 0x7ecc381ffc02 */
The hardware will
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,

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,
