DRM_MODE_FLAG_PIXDATA_POSEDGE is easier to get your head around if you know it is mapped from the DISPLAY_FLAGS_ version. PDATEN and PPIXDATEDGE don't exactly map to things like EDID field names either.. > +#define DRM_MODE_FLAG_PPIXDATEDGE (1<<24) > +#define DRM_MODE_FLAG_NPIXDATEDGE (1<<25) -- Matt Sealey <neko@xxxxxxxxxxxxx> _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
