This series makes PCI interrupt routing in the VIA south bridges more compliant
to the PCI specification. It aims to help bringing audio output support to the
ppc/pegasos2 machine [1].
v2:
* Remove audio patches which were included for proof of concept
Testing done with via-ac97 audio patches on top:
* `make check`
* `qemu-system-ppc -M pegasos2 -rtc base=localtime -device
ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso -kernel
morphos-3.17/boot.img`
-> There is a nice sound when the Desktop becomes visible.
* `qemu-system-ppc -M pegasos2 -bios pegasos2.rom -rtc base=localtime -device
ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso`
-> There is a nice sound when the Desktop becomes visible.
* `qemu-system-ppc -M pegasos2 -bios pegasos2.rom -rtc base=localtime -device
ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso -device
usb-mouse -device usb-kbd`
-> The machine hangs when audio is supposed to play while the mouse is moved.
This behavior can also be reproduced in v1.
