So far the CHARON-AXP emulators do not emulate BroadCom BCM5703. Instead, emulation of DECchip 21143 is used.

AlphaServer ES40 (10 PCI slots)
In addition to 10 PCI vacant slots there are 3 PCI positions occupied by on-board devices. All 13 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.
Slot | pci_<N> | device | function | irq | Description |
---|---|---|---|---|---|
5 | 1 | 1 | 0 | 24 | <option> |
6 | 1 | 2 | 0 | 28 | <option> |
7 | 1 | 3 | 0 | 32 | <option> |
8 | 1 | 4 | 0 | 36 | <option> |
9 | 1 | 5 | 0 | 40 | <option> |
10 | 1 | 6 | 0 | 44 | <option> |
1 | 0 | 1 | 0 | 8 | <option> |
2 | 0 | 2 | 0 | 19 | <option> |
3 | 0 | 3 | 1 | 16 | <option> |
4 | 0 | 4 | 0 | 20 | <option> |
- | 0 | 5 | 0 | - | ALi M1543C PCI ISA bridge |
- | 0 | 15 | 0 | - | ALi M1543C PCI ISA bridge |
- | 0 | 19 | 0 | - | ALi M1543C PCI USB adapter |
The IRQ stands for bit position in DRIR of Tsunami/Typhoon chip. It has nothing to do with “ISA” style interrupts which are routed to IRQ 55 (including ALi M1543C PCI IDE/ATAPI controller).
So far the CHARON-AXP emulators do not support virtual ALi M1543C PCI USB adapter. So position of the device 19, function 0 on the PCI 0 remains empty.
