This patch completely rewrites VIASave and VIARestore functions.
Completely rewrites VIASave and VIARestore functions inside via_vgahw.c.
It now saves and restores virtually all VIA Technologies defined
extended VGA registers. The previous code did not save all extended VGA
registers, so many registers were not being restored at all.
That being said, Chrome 9 HD HDMI or DisplayPort registers are not
being saved or restored in this patch.
The compiled device driver was tested on the following computer.
- Epic 1314 laptop (MSI VR321 laptop equivalent, VN896 chipset)
with Lubuntu 12.04 i386
