Doing a bit of digging here for my long-standing CBB+SIO interupt and
buffer problem -
one machine I've tested against was an OpenBSD machine, which didn't
always work to handle the cardbus sio card on a PCI cardbus adapter
tuning up some of the device flags in:
seems to have alleviated the problem for that os..
I'm just only starting to get up to speed on how DF handles these types
of things (namely initial PIC / interrupt layout at boot time device
enumeration), but am wondering if anyone familiar with this area of the
code has any comments / advice w/r/t the capabilities of the DF bios
and the various quirks / fixup mentioned in the link above..
looking to possibly investigate fixing up some of these issues over time.
