You can already do that! HAS_DISPLAY() takes either i915 or display. So maybe make that change now. In the future, only display code should have HAS_DISPLAY() anyway, not i915 or xe core. It's not an option that the caller does the checks. > > Signed-off-by: Imre Deak <[email protected]> > --- > drivers/gpu/drm/i915/display/intel_encoder.c | 22 +++++++++++--------- > drivers/gpu/drm/i915/display/intel_encoder.h | 7 +++---- > drivers/gpu/drm/i915/i915_driver.c | 6 +++--- > 3 files changed, 18 insertions(+), 17 deletions(-) > > diff --git a/drivers/gpu/drm/i915/display/intel_encoder.c > b/drivers/gpu/drm/i915/display/intel_encoder.c > index 8a1dccb893a37..8e73d18a522d4 100644 > --- a/drivers/gpu/drm/i915/display/intel_encoder.c > +++ b/drivers/gpu/drm/i915/display/intel_encoder.c > @@ -38,8 +38,9 @@ void intel_encoder_link_check_queue_work(struct > intel_encoder *encoder, int dela > &encoder->link_check_work, msecs_to_jiffies(delay_ms)); > } > > -void intel_encoder_suspend_all(struct drm_i915_private *i915) > +void intel_encoder_suspend_all(struct intel_display *display) > { > + struct drm_i915_private *i915 = to_i915(display->drm); > struct intel_encoder *encoder; > > if (!HAS_DISPLAY(i915)) > @@ -49,19 +50,20 @@ void intel_encoder_suspend_all(struct drm_i915_private > *i915) > * TODO: check and remove holding the modeset locks if none of > * the encoders depends on this. > */ > - drm_modeset_lock_all(&i915->drm); > - for_each_intel_encoder(&i915->drm, encoder) > + drm_modeset_lock_all(display->drm); > + for_each_intel_encoder(display->drm, encoder) > if (encoder->suspend) > encoder->suspend(encoder); > - drm_modeset_unlock_all(&i915->drm); > + drm_modeset_unlock_all(display->drm); > > - for_each_intel_encoder(&i915->drm, encoder) > + for_each_intel_encoder(display->drm, encoder) > if (encoder->suspend_complete) > encoder->suspend_complete(encoder); > } > > -void intel_encoder_shutdown_all(struct drm_i915_private *i915) > +void intel_encoder_shutdown_all(struct intel_display *display) > { > + struct drm_i915_private *i915 = to_i915(display->drm); > struct intel_encoder *encoder; > > if (!HAS_DISPLAY(i915)) > @@ -71,13 +73,13 @@ void intel_encoder_shutdown_all(struct drm_i915_private > *i915) > * TODO: check and remove holding the modeset locks if none of > * the encoders depends on this. > */ > - drm_modeset_lock_all(&i915->drm); > - for_each_intel_encoder(&i915->drm, encoder) > + drm_modeset_lock_all(display->drm); > + for_each_intel_encoder(display->drm, encoder) > if (encoder->shutdown) > encoder->shutdown(encoder); > - drm_modeset_unlock_all(&i915->drm); > + drm_modeset_unlock_all(display->drm); > > - for_each_intel_encoder(&i915->drm, encoder) > + for_each_intel_encoder(display->drm, encoder) > if (encoder->shutdown_complete) > encoder->shutdown_complete(encoder); > } > diff --git a/drivers/gpu/drm/i915/display/intel_encoder.h > b/drivers/gpu/drm/i915/display/intel_encoder.h > index e6cd74576f78e..3fa5589f0b1ce 100644 > --- a/drivers/gpu/drm/i915/display/intel_encoder.h > +++ b/drivers/gpu/drm/i915/display/intel_encoder.h > @@ -6,8 +6,7 @@ > #ifndef __INTEL_ENCODER_H__ > #define __INTEL_ENCODER_H__ > > -struct drm_i915_private; > - Ah, this is why you missed the superfluous space. ;) BR, Jani. > +struct intel_display; > struct intel_encoder; > > void intel_encoder_link_check_init(struct intel_encoder *encoder, > @@ -15,7 +14,7 @@ void intel_encoder_link_check_init(struct intel_encoder > *encoder, > void intel_encoder_link_check_queue_work(struct intel_encoder *encoder, int > delay_ms); > void intel_encoder_link_check_flush_work(struct intel_encoder *encoder); > > -void intel_encoder_suspend_all(struct drm_i915_private *i915); > -void intel_encoder_shutdown_all(struct drm_i915_private *i915); > +void intel_encoder_suspend_all(struct intel_display *display); > +void intel_encoder_shutdown_all(struct intel_display *display); > > #endif /* __INTEL_ENCODER_H__ */ > diff --git a/drivers/gpu/drm/i915/i915_driver.c > b/drivers/gpu/drm/i915/i915_driver.c > index e9e38ed246f66..fb8e9c2fcea53 100644 > --- a/drivers/gpu/drm/i915/i915_driver.c > +++ b/drivers/gpu/drm/i915/i915_driver.c > @@ -956,8 +956,8 @@ void i915_driver_shutdown(struct drm_i915_private *i915) > if (HAS_DISPLAY(i915)) > intel_display_driver_suspend_access(i915); > > - intel_encoder_suspend_all(i915); > - intel_encoder_shutdown_all(i915); > + intel_encoder_suspend_all(&i915->display); > + intel_encoder_shutdown_all(&i915->display); > > intel_dmc_suspend(i915); > > @@ -1040,7 +1040,7 @@ static int i915_drm_suspend(struct drm_device *dev) > if (HAS_DISPLAY(dev_priv)) > intel_display_driver_suspend_access(dev_priv); > > - intel_encoder_suspend_all(dev_priv); > + intel_encoder_suspend_all(&dev_priv->display); > > /* Must be called before GGTT is suspended. */ > intel_dpt_suspend(dev_priv); -- Jani Nikula, Intel
