Currently the only case for "not applicable" is when the monitor is disconnected, but sicne the properties are so interdependent, there might be a case in the future where e.g. a color format that has no differentiation between full and limited arises. When there is no special unset/not applicable option, the userspace has to know exactly when an option is valid or not, possible requiring additional logic. Setting a "not applicable" value allows userspace to be more dumb, without much hassle on the kernelspace side. > > > Thanks, > pq > _______________________________________________ > amd-gfx mailing list > amd-gfx@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/amd-gfx
