From b49982de6a52fdb7d0360d608badb103d15c04f1 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 25 Apr 2014 15:14:47 -0700 Subject: [PATCH] i965: Fix intel_bufferobj_buffer range for blit drawpixels. If the stride wasn't width*cpp, we wouldn't track how much of the src is busy, and allow a subdata into the end to proceed unsynchronized.
