PSR currently when enabled results in semi-permanent freezes or noticeable cursor lags. https://patchwork.freedesktop.org/series/37598/ will fix long freezes due to frame counter resets. This series has three more fixes - Patch 1 eliminates PSR exit for flips and makes us rely on the HW to do it. Patch 2 fixes cusor move lag by relying on HW to exit PSR. Patch 3 fixes temporary freeze seen with fbdev. With both the series applied, PSR on my SKL ThinkPad feels pretty good. Dhinakaran Pandiyan (2): drm/i915/psr: HW tracking for cursor moves to fix lags. drm/i915/psr: Wait for PSR transition to complete before exiting. Rodrigo Vivi (1): drm/i915/psr: Use more PSR HW tracking. drivers/gpu/drm/i915/i915_drv.h | 2 ++ drivers/gpu/drm/i915/i915_gem.c | 2 +- drivers/gpu/drm/i915/intel_drv.h | 3 ++- drivers/gpu/drm/i915/intel_frontbuffer.c | 2 +- drivers/gpu/drm/i915/intel_psr.c | 24 +++++++++++++++++++++++- 5 files changed, 29 insertions(+), 4 deletions(-) -- 2.14.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
