I bisected, and it got solved with this commit: commit 02ca66fbc3e2b272afcb9bae66348d3b1900e2c3 Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> Date: Thu Aug 21 14:41:17 2014 -0700 i965: Use unsynchronized maps for the program cache on LLC platforms. There's no reason to stall on pwrite - the CPU always appends to the buffer and never modifies existing contents, and the GPU never writes it. Further, the CPU always appends new data before submitting a batch that requires it. This code predates the unsynchronized mapping feature, so we simply didn't have the option when it was written. Ideally, we would do this for non-LLC platforms too, but unsynchronized mapping support only exists for LLC systems. Saves a bunch of stall avoidance copies when uploading shaders. v2: Rebase on changes to previous patch.
