You probably want "RANGE | IMMUTABLE" here (and also on GAMMA_LUT_SIZE below). ...snip... > + <td valign="top" >“GAMMA_LUT_SIZE”</td> > + <td valign="top" >IMMUTABLE</td> > + <td valign="top" ></td> > + <td valign="top" >CRTC</td> > + <td valign="top" >DRM property to gives the size of the LUT to > + be set on the GAMMA_LUT property (the size depends on the > + underlying hardware).</td> > + </tr> > + <tr> > <td rowspan="20" valign="top" >i915</td> > <td rowspan="2" valign="top" >Generic</td> > <td valign="top" >"Broadcast RGB"</td> ...snip... > diff --git a/drivers/gpu/drm/drm_crtc.c b/drivers/gpu/drm/drm_crtc.c > index d40bab2..6f96c04 100644 > --- a/drivers/gpu/drm/drm_crtc.c > +++ b/drivers/gpu/drm/drm_crtc.c > @@ -1542,6 +1542,41 @@ static int drm_mode_create_standard_properties(struct drm_device *dev) > return -ENOMEM; > dev->mode_config.prop_mode_id = prop; > > + prop = drm_property_create(dev, > + DRM_MODE_PROP_BLOB, > + "DEGAMMA_LUT", 0); > + if (!prop) > + return -ENOMEM; > + dev->mode_config.degamma_lut_property = prop; > + > + prop = drm_property_create(dev, > + DRM_MODE_PROP_IMMUTABLE, As noted above, you still need to OR in a valid property type (in this case DRM_MODE_PROP_RANGE); otherwise you'll trip over the the check in drm_property_type_valid() that gets called at the end of drm_property_create().
