From 0e850452d1af72ae2af3a77892483bd1564af481 Mon Sep 17 00:00:00 2001 From: Topi Pohjolainen Date: Fri, 22 Apr 2016 16:01:12 +0300 Subject: [PATCH] i965/blorp/gen6: Use normal base state address setup This is identical to the blorp version which only differs in case fragment shader isn't used. In that case blorp would reset batch buffer address to zero. This is not really needed, and having blorp to use base state address setup that is compatible with normal upload allows one to skip resetting it.
