From 9e4c8acd7814186673c4945c7045124ebbcd125f Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Sat, 16 Jan 2016 15:05:51 -0800 Subject: [PATCH] i965: Trigger CS state reemission when new sampler state is uploaded. This reuses the NEW_SAMPLER_STATE_TABLE state bit (currently only used on pre-Gen7 hardware) to signal that the sampler state tables have changed in order to make sure that the GPGPU interface descriptor is updated.
