There is no specific mga driver, even when DRM has a mgadrm driver.



>(Right now I see â??drm at vga0 not configuredâ?? in the dmesg.) Not that I plan to do much with this system on console, but Iâ??m surprised to see VGA fallback here.

So far, the mga DRM2 driver isn't ready. DRM1 includes a mga driver, but
I'm not sure how functional it still is.

These devices aren't configured as separate PCI devices. E.g. the first
one would be a DMA channel, and the second one is an interrupt controller.
For such devices, detecting and configuring them as late as the PCI
configuration would be too late. Instead, information from SMBIOS and
ACPI are used to find them, and configuration happens earlier and
unfortunately not as transparent as with a PCI device.

Some devices are also not really documented, support would be difficult.

Probably. Some information could be gleaned from Linux. E.g. the 103c:3306
device includes a watchdog timer and can be used to identify an NMI. For
some people that might be useful.
