But that's maybe something for after all the atomic work has stablized a bit. -Daniel > --- > drivers/gpu/drm/i915/intel_display.c | 19 +++++++++++++++++++ > 1 file changed, 19 insertions(+) > > diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c > index d1a4de8..fdea96c 100644 > --- a/drivers/gpu/drm/i915/intel_display.c > +++ b/drivers/gpu/drm/i915/intel_display.c > @@ -13322,6 +13322,23 @@ static bool primary_get_hw_state(struct intel_crtc *crtc) > return I915_READ(DSPCNTR(crtc->plane)) & DISPLAY_PLANE_ENABLE; > } > > +static void primary_update_size(struct intel_crtc *crtc) > +{ > + struct intel_plane *primary = to_intel_plane(crtc->base.primary); > + > + if (!crtc->primary_enabled) > + return; > + > + primary->crtc_x = 0; > + primary->crtc_y = 0; > + primary->crtc_w = crtc->config.pipe_src_w; > + primary->crtc_h = crtc->config.pipe_src_h; > + primary->src_x = 0; > + primary->src_y = 0; > + primary->src_w = crtc->config.pipe_src_w << 16; > + primary->src_h = crtc->config.pipe_src_h << 16; > +} > + > static void intel_modeset_readout_hw_state(struct drm_device *dev) > { > struct drm_i915_private *dev_priv = dev->dev_private; > @@ -13332,6 +13349,7 @@ static void intel_modeset_readout_hw_state(struct drm_device *dev) > int i; > > for_each_intel_crtc(dev, crtc) { > + > memset(&crtc->config, 0, sizeof(crtc->config)); > > crtc->config.quirks |= PIPE_CONFIG_QUIRK_INHERITED_MODE; > @@ -13341,6 +13359,7 @@ static void intel_modeset_readout_hw_state(struct drm_device *dev) > > crtc->base.enabled = crtc->active; > crtc->primary_enabled = primary_get_hw_state(crtc); > + primary_update_size(crtc); > > DRM_DEBUG_KMS("[CRTC:%d] hw state readout: %s\n", > crtc->base.base.id, > -- > 1.9.1 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
