I mentioned earlier that grepping OvmfPkg for PCI_LIB_ADDRESS would be
necessary. See PciInitialization() in
"OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c".
//
// Bus 0, Device 1, Function 0 - PCI to ISA Bridge
//
PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x3c), 0x00);
PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x60), 0x0b); // LNKA routing target
PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x61), 0x0b); // LNKB routing target
PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x62), 0x0a); // LNKC routing target
PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x63), 0x0a); // LNKD routing target
This is not appropriate for q35. See "ICH9 PCI to ISA irq remapping" in
qemu's "q35-acpi-dsdt.dsl" file, vs. "PIIX PCI to ISA irq remapping" in
"acpi-dsdt.dsl".
The above was added in 05c89c7f.
Thanks
Laszlo
