W.r.t. the aspect ratio userspace story, there was some discussion on #dri-devel recently about extending the xrandr protocol for 3d stereo support. If that is going to happen then it might make sense to try and get the aspect ratio stuff also included at the same time so that we would only have to deal with one protocol bump. > > Signed-off-by: Jose Abreu <joabreu@xxxxxxxxxxxx> > Cc: Carlos Palminha <palminha@xxxxxxxxxxxx> > Cc: dri-devel@xxxxxxxxxxxxxxxxxxxxx > --- > include/uapi/drm/drm_mode.h | 9 +++++++++ > 1 file changed, 9 insertions(+) > > diff --git a/include/uapi/drm/drm_mode.h b/include/uapi/drm/drm_mode.h > index 8c67fc0..62e679c 100644 > --- a/include/uapi/drm/drm_mode.h > +++ b/include/uapi/drm/drm_mode.h > @@ -89,6 +89,8 @@ > #define DRM_MODE_PICTURE_ASPECT_NONE 0 > #define DRM_MODE_PICTURE_ASPECT_4_3 1 > #define DRM_MODE_PICTURE_ASPECT_16_9 2 > +#define DRM_MODE_PICTURE_ASPECT_64_27 3 > +#define DRM_MODE_PICTURE_ASPECT_256_135 4 > > /* Aspect ratio flag bitmask (4 bits 22:19) */ > #define DRM_MODE_FLAG_PIC_AR_MASK (0x0F<<19) > @@ -98,6 +100,13 @@ > (DRM_MODE_PICTURE_ASPECT_4_3<<19) > #define DRM_MODE_FLAG_PIC_AR_16_9 \ > (DRM_MODE_PICTURE_ASPECT_16_9<<19) > +#define DRM_MODE_FLAG_PIC_AR_64_27 \ > + (DRM_MODE_PICTURE_ASPECT_64_27<<19) > +#define DRM_MODE_FLAG_PIC_AR_256_135 \ > + (DRM_MODE_PICTURE_ASPECT_256_135<<19) > + > +/* HDMI 2.0+ mode flag: will only be set if client supports it */ > +#define DRM_MODE_FLAG_HDMI2 (1<<23) > > /* DPMS flags */ > /* bit compatible with the xorg definitions. */ > -- > 1.9.1 > > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Ville Syrjälä Intel OTC _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
