[Mesa-dev] [PATCH 3/3] i965: Prefer Y-tiling on Gen6+.

2013-04-08 Thread Kenneth Graunke
In the past, we preferred X-tiling for color buffers because our BLT code couldn't handle Y-tiling. However, the BLT paths have been largely replaced by BLORP on Gen6+, which can handle any kind of tiling. We hadn't measured any performance improvement in the past, but that's probably because com
