No, we never have. Even in 3.*, we usually (but not always) set the blanking interval to be the same as the space between [HV]Display and [HV]Total. In the ND, that's even more the case, as the common layer (and vgaHW) tries harder to eliminate overscans. The intent at the time was to implement some kind of overscan option in vgaHW, but that never got done (it wouldn't deal with non-VGA CRTC's anyway). > I know the CrtcVBlankStart, etc... get passed to the drivers. > I'm just not sure how they get explicitly set. They are set in xf86SetModeCrtc() in common/xf86Mode.c although the limit checks there are specific to a VGA CRTC.
