I have no idea. I'm not even sure that such docs do exist.
One could expect to find IRQ routing in the tech reference
manual, but there is no such info...
Basically, we need to fill following table:
Primary bus
IdSel INTA INTB INTC INTD
21052 0x0d - - - -
SIO 0x0e 23 - - -
21143 0x0f 44 - - -
64-Slot 0x11 43 ? ? ?
Secondary bus
IdSel INTA INTB INTC INTD
Slot 0 0x08 ? ? ? ?
Slot 1 0x09 ? ? ? ?
Slot 2 0x0a 27 26 ? ?
Slot 3 0x0b ? ? ? ?
Slot 4 0x0c 35 ? ? ?
53c875 0x0d 20 - - -
These IRQ values were found in the logs and lspci outputs that I got
from Michal 2 months ago. The interesting one is INTB for slot 2 -
it was IRQ assigned to ethernet on a scsi+ethernet combo card. It
allows me to guess that IRQs for slot 2 are 27, 26, 25, 24, for
slot 4 - 35, 34, 33, 32 etc.
We need to find INTA assignments for slots 0, 1 and 3 though.
It could be easily done with any working PCI card placed in
these slots and 'lspci -vv'.
