From 995d304774966bf1e3013b5bf7df554b3d807b17 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 19 Nov 2014 07:37:47 -0800 Subject: [PATCH] drm/i915: VLV/CHV PSR Software timer mode This patch introduces exit/activate functions for PSR on VLV+. Since on VLV+ HW cannot track frame updates and force PSR exit let's use fully SW tracking available. v2: Rebase over intel_psr.c; Remove Single Frame update transitioning from state 3 to 5 directly; Fake a software invalidation for sprites and cursor so we don't miss any screen update; v3: As pointed out by Durgadoss msecs_to_jiffies used on wait_for only uses int, so let's use 1 instead. Althought the 1/4 of this is needed for the transition let's use 1 for simplicity; Also fix comments as suggested by Durgadoss Cc: Durgadoss R Signed-off-by: Rodrigo Vivi Reviewed-by: Durgadoss R Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
