Subject: [PATCH 0/3] PSR lag fixes
Date: Sun, 11 Feb 2018 22:08:02 -0800 [thread overview]
Message-ID: <20180212060805.3000-1-dhinakaran.pandiyan@intel.com> (raw)
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.
