From 295605c930270a5b90f847b79474507d8b0c9e9c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 24 Aug 2017 11:40:31 -0700 Subject: intel/cs: Push subgroup ID instead of base thread ID We're going to want subgroup ID for SPIR-V subgroups eventually anyway. We really only want to push one and calculate the other from it. It makes a bit more sense to push the subgroup ID because it's simpler to calculate and because it's a real API thing. The only advantage to pushing the base thread ID is to avoid a single SHL in the shader.
