From: Akash Goel <akash.goel@xxxxxxxxx> This patch series provides support to create unbound write combining mapping for GEM objects. This is to improve the CPU write operation performance, as with such mapping, writes are almost 50% faster than with mmap_gtt. The new mapping is exercised by the IGT tests :- igt/gem_mmap_wc, igt/gem_tiled igt/gem_concurrent_blit, igt/gem_gtt_speed & igt/gem_fence_upload.
