Hi,
The graphics ddk documentation says that the vbios calls are meant only
for x86 based systems. If I want to port a driver from x-86 to non-x86
platforms, how should I go about it? Is it also feasible to port the
vbios calls to the non-x86 platforms ?
TIA & Regards,
Rajan

It depends on whether the driver you’re porting made any vbios calls
in the first place. Drivers that program the hardware directly for
everything and never call the BIOS are easier to port.
If you are trying to port a driver that does make BIOS calls you’ll
have a lot of work to do; you’ll need to re-implement any functionality
that was relying on the BIOS.
