From 1cd8b21aa22c4fe8835abe614da5fa989c66dca9 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 13 Sep 2013 14:07:03 -0400 Subject: [PATCH] drm/radeon/dpm: rework auto performance level enable Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence. Fixes dpm resume on SI.
