GIO bus driver for Linux 2.6
I am trying to resurrect the GIO bus Linux driver. GIO is the expansion bus
of various SGI machines including
IP12 (Indigo), IP20 (Indigo R4x00), IP22 (Indy/Indigo2),
IP26 (Power Indigo2) and IP28 (Indigo2 R10000). So far it has only been
tested on IP22 (Indy).
"Improvements" and changes from old interface
Example outputWhen the module is loaded some information is printed:
GIO: Scanning for GIO cards... GIO: Card 0x04 @ 0x1f000000 (GFX slot) GIO: Card 0x7f @ 0x1f400000 (EXP0 slot)You can get information using sysfs:
carrot:~# systool -v -b gio Bus = "gio" Device = "00:00" Device path = "/sys/devices/00:00" id = "04" slot_name = "GFX" Device = "00:01" Device path = "/sys/devices/00:01" id = "7F" slot_name = "EXP0"
