From: Sourab Gupta <sourab.gupta@xxxxxxxxx> This patch series enables the framework for using MMIO flips in place of Blitter ring based flips. This is useful for Media power well residency optimization. These may be enabled on architectures where Render and Blitter engines reside in different power wells. The blitter ring is currently being used just for command streamer based flip calls. The decision to use MMIO flips can be made based on workloads to give 100% residency for Media power well. Sourab Gupta (3): drm/i915: Replaced Blitter ring based flips with MMIO flips drm/i915: Selection of MMIO vs CS flip at page flip time drm/i915: Make module param for MMIO flip selection as tristate drivers/gpu/drm/i915/i915_dma.c | 1 + drivers/gpu/drm/i915/i915_drv.h | 8 ++ drivers/gpu/drm/i915/i915_gem.c | 2 +- drivers/gpu/drm/i915/i915_irq.c | 3 + drivers/gpu/drm/i915/i915_params.c | 6 ++ drivers/gpu/drm/i915/intel_display.c | 173 ++++++++++++++++++++++++++++++++++- drivers/gpu/drm/i915/intel_drv.h | 6 ++ 7 files changed, 197 insertions(+), 2 deletions(-) -- 1.8.5.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
