From 67fec964525a88c975902bdfb4078d722d4f04bf Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 29 Nov 2016 01:37:49 -0800 Subject: [PATCH] i965: Stop re-uploading push constants after URB reconfiguration. Previously we would re-upload the constant data to the batchbuffer, then re-emit the packets. We only need to do the last step (causing the existing data in the batchbuffer to be re-uploaded to the push constant staging area in the L3). Now that we've separated the two, it's pretty easy to accomplish.
