From: Abdiel Janulgue <abdiel.janulgue@xxxxxxxxxxxxxxx> This is a re-spin of my resource streamer patchset from October adapted to enable the feature on Broadwell instead. The resource streamer is a hw-feature that helps in reducing commands being submitted by the CPU. Haswell initially has this feature. Unfortunately, HSW seems to have problems switching between non-RS and RS-enabled commands[1]. On BDW however it works seamlessly as expected. The i-g-t test comes next on a separate patch-series. -- [1] http://lists.freedesktop.org/archives/intel-gfx/2014-May/044577.html Abdiel Janulgue (2): drm/i915/bdw: Enable resource streamer bits on MI_BATCH_BUFFER_START drm/i915/bdw: Expose I915_EXEC_RESOURCE_STREAMER flag drivers/gpu/drm/i915/i915_gem_execbuffer.c | 8 ++++++++ drivers/gpu/drm/i915/i915_reg.h | 1 + drivers/gpu/drm/i915/intel_ringbuffer.c | 3 ++- drivers/gpu/drm/i915/intel_ringbuffer.h | 1 + include/uapi/drm/i915_drm.h | 7 ++++++- 5 files changed, 18 insertions(+), 2 deletions(-) _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
