So please pay attention, especially if you start getting lots of WARNs when you enter runtime PM :) Thanks, Paulo > --- > drivers/gpu/drm/i915/intel_pm.c | 4 ++++ > 1 file changed, 4 insertions(+) > > diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c > index c644a6f..273e806 100644 > --- a/drivers/gpu/drm/i915/intel_pm.c > +++ b/drivers/gpu/drm/i915/intel_pm.c > @@ -5301,6 +5301,8 @@ void intel_display_power_get(struct drm_device *dev, > struct i915_power_well *power_well; > int i; > > + intel_runtime_pm_get(dev_priv); > + > power_domains = &dev_priv->power_domains; > > mutex_lock(&power_domains->lock); > @@ -5332,6 +5334,8 @@ void intel_display_power_put(struct drm_device *dev, > __intel_power_well_put(dev, power_well); > > mutex_unlock(&power_domains->lock); > + > + intel_runtime_pm_put(dev_priv); > } > > static struct i915_power_domains *hsw_pwr; > -- > 1.8.3.1 > -- Paulo Zanoni _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
