Gary,
How much testing did you do on the noise code that you added to the 965
driver? I modified Mesa's progs/glsl/noise.c demo to use NOISE3
opcodes, and it causes my GPU to hard-lock. This is with today's bits
(kernel, Mesa, X server, and 2D driver).
I first encountered this when I was trying to add support for
OPCODE_NOISE4. However, it occurs without any of my changes.
