We might be leaving the GPU Frequency (and thus vnn) high during the suspend. Force gt to move to lowest freq while suspending. v2: Fixed typo in commit message (Deepak) v3: Force gt to lowest freq in suspend_gt_powersave (Daniel) v4: Add GPU min freq set _after_ we've cancelled the rps works (Daniel) Signed-off-by: Deepak S Reviewed-by: Jesse Barnes Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_pm.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index 9585f1517fa9..f55347f3ac7f 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -4974,6 +4974,9 @@ void intel_suspend_gt_powersave(struct drm_device *dev) flush_delayed_work(&dev_priv->rps.delayed_resume_work); cancel_work_sync(&dev_priv->rps.work); + + /* Force GPU to min freq during suspend */ + gen6_rps_idle(dev_priv); } void intel_disable_gt_powersave(struct drm_device *dev) -- 2.20.1
