AMD SB800: PCI(E) slots on Persimmon
(routine.asl):Set the correct device number in the pcie interrupt routine in ACPI asl.
The device number is decided by which address pin is connected to IDSEL.
Table 3-1: IDSEL Generation
Primary Address AD[15::11] Secondary Address AD[31::16]
0 0000 0000 0000 0000 0001
0 0001 0000 0000 0000 0010
0 0010 0000 0000 0000 0100
0 0011 0000 0000 0000 1000
0 0100 0000 0000 0001 0000
0 0101 0000 0000 0010 0000
0 0110 0000 0000 0100 0000
0 0111 0000 0000 1000 0000
0 1000 0000 0001 0000 0000
0 1001 0000 0010 0000 0000
0 1010 0000 0100 0000 0000
0 1011 0000 1000 0000 0000
0 1100 0001 0000 0000 0000
0 1101 0010 0000 0000 0000
0 1110 0100 0000 0000 0000
0 1111 1000 0000 0000 0000
1 xxxx 0000 0000 0000 0000
On persimmon, PCI slot 0's IDSEL is connected to AD19, so the device number is 3.
Slot 1's IDSEL is connected to AD20, so the device number is 4.
(devicetree.cb): Enable the PCIE bridge which is connected to the PCIE slot.
