From: Kristian Høgsberg Date: Mon, 7 Jul 2014 21:43:30 +0000 (-0700) Subject: i965: Assign PS kernel start pointers when we decide which kernels to use X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=416dd873e8e0cbca1477344a94a7c2e0c9a6c25b;p=mesa.git i965: Assign PS kernel start pointers when we decide which kernels to use Right now we decide which kernels to use and the GRF start offsets in one place and emit the kernel pointers later. The logic of how to map 8, 16 and 32 kernels to kernel start pointers follows the same logic as which GRF start offsets to use, so lets figure out these two things in one place.
