I was playing with some stuff to muck with the video card on the sun5
I have.
dmesg shows;
pci2: <display, VGA> at device 2.0 (no driver attached)
pciconf -lv shows
none0@pci1:2:0: class=0x030000 card=0x00000000 chip=0x47541002 rev=0x9a hdr=0x00
vendor = 'ATI Technologies'
device = 'Mach 64 GT Rage 3D II Graphics Accelerator'
class = display
subclass = VGA
I wrote some code based on the pciconf code to basically go fetch
things from the video card, but, it was failing, all values were coming
back 0xffffffff (-1?) (works in i386, but, I only have one PCI bus there).
So I went back to basics...
root@orchid~akm#pciconf -l
[snip]
none0@pci1:2:0: class=0x030000 card=0x00000000 chip=0x47541002 rev=0x9a hdr=0x00
root@orchid~akm#pciconf -r pci1:2:0 0
ffffffff
root@orchid~akm#pciconf -r pci2:2:0 0
47541002
There's an off by one error somewhere, the pc_bus reported by
ioctl(fd, PCIOCGETCONF, &pc) is coming back wrong.
