Actually, most code is already in the KGIcon ViRGE driver to support that.
The ViRGE has completely functional vertical retrace interrupt code, but
at the moment, nothing is done with it. Reason: I have not seen a
mechanism to get the sync to userspace neatly. (Maybe some
CHIP_WAITFORRECTRACE ioctl ? We never intended to be real-time, so some
while not in retrace schedule (); can do the job here)

You're talking about software emulation of the functions you describe or
hardware support ?
Want to help writing 3D accelleration in the KGIcon S3 Virge driver ?
