From ab585dea120fa20313b1b5a3be2b3d614f094678 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 24 Mar 2015 12:40:09 -0700 Subject: [PATCH] drm/i915: kill i915.powersave This flag was being mostly used as a meta flag in some cases and not covering other cases. One of the risks is that it was masking some frontbuffer trackings without disabling PSR. So, better to kill this at once and avoid umbrella parameters.
