Plus I think a note in the attach function that sets up hdcp for a connector that it should be used. Plus we need an ack from userspace people (weston?) that they're using this new uapi and are happy with it. > +void drm_hdcp_update_content_protection(struct drm_connector *connector, > + u64 val) > +{ > + struct drm_device *dev = connector->dev; > + struct drm_connector_state *state = connector->state; > + > + WARN_ON(!drm_modeset_is_locked(&dev->mode_config.connection_mutex)); > + if (state->content_protection == val) > + return; > + > + state->content_protection = val; > + drm_sysfs_connector_status_event(connector, > + dev->mode_config.content_protection_property); > +} > +EXPORT_SYMBOL(drm_hdcp_update_content_protection); With all that addressed has my Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> > diff --git a/include/drm/drm_hdcp.h b/include/drm/drm_hdcp.h > index 145c81ba1e09..9457c7ec0d37 100644 > --- a/include/drm/drm_hdcp.h > +++ b/include/drm/drm_hdcp.h > @@ -304,4 +304,6 @@ struct drm_connector; > bool drm_hdcp_ksvs_revocated(struct drm_device *dev, u8 *ksvs, u32 ksv_count); > int drm_connector_attach_content_protection_property( > struct drm_connector *connector, bool hdcp_content_type); > +void drm_hdcp_update_content_protection(struct drm_connector *connector, > + u64 val); > #endif > -- > 2.19.1 >

drm function is defined and exported to update a connector's content protection property state and to generate a uevent along with it. v2: Update only when state is different from old one.
