From d298ce5e25c1719cc32a2fd9373e1e72c50329f0 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 19 Nov 2014 07:34:04 -0800 Subject: [PATCH] drm/i915: remove PSR BDW single frame update. Single frame update is a feature available on BDW for PSR that allows Source to send Sink only one frame and get it updated. Usually useful when page flipping. However with our frontbuffer tracking where we force psr exit on flips we don't need this feature. Also after it got added here many workaround was added to documentation to mask some bits when using single frame update. So the safest thing is to just stop using it. v2: Rebase after removing skip aux one and fixing typo on commit message.
