Subject: [PATCH 0/5] VT82xx PCI fixes and audio output support
Date: Thu, 23 Feb 2023 21:20:48 +0100 [thread overview]
Message-ID: <20230223202053.117050-1-shentey@gmail.com> (raw)
This series is v2 of [1] ("[PATCH 0/5] Pegasos2 fixes and audio output
support"). It makes PCI interrupt routing on the VIA south bridges more
compliant to the PCI specification and adds partial implementation of the
via-ac97 sound part enough to get audio output working on the ppc/pegasos2
machine.
All credits for implementing AC'97 support go to Zoltan who would like this
series to be merged for QEMU 8.0.
v2:
* Rework PCI IRQ routing in the VIA south bridges
* Use pci_set_irq() rather than via_isa_set_irq() in via-ac97
Testing done:
* `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.
