[PATCH v3 0/4] Fix IRQ routing in via south bridge

Philippe, Could this be merged for 8.2 as it fixes USB on the amigaone machine? This would be useful as usb-storage is the simplest way to share data with the host with these machines. This is a slight change from v2 adding more comments and improving commit messages and clean things a bit but

[PATCH v3 1/4] hw/isa/vt82c686: Bring back via_isa_set_irq()

The VIA integrated south bridge chips combine several functions and allow routing their interrupts to any of the ISA IRQs also allowing multiple sources to share the same ISA IRQ. E.g. pegasos2 firmware configures everything to use IRQ 9 but amigaone routes them to separate ISA IRQs so the current

[PATCH v3 2/4] hw/usb/vt82c686-uhci-pci: Use ISA instead of PCI interrupts

This device is part of a superio/ISA bridge chip and IRQs from it are routed to an ISA interrupt. Use via_isa_set_irq() function to implement this in a vt82c686-uhci-pci specific irq handler. This reverts commit 422a6e8075752bc5342afd3eace23a4990dd7d98. Signed-off-by: BALATON Zoltan ---

[PATCH v3 4/4] hw/audio/via-ac97: Route interrupts using via_isa_set_irq()

This device is a function of VIA south bridge and should allow setting interrupt routing within that chip. This is implemented in via_isa_set_irq(). Fixes: eb604411a78b82c468e2b8d81a9401eb8b9c7658 Signed-off-by: BALATON Zoltan --- hw/audio/via-ac97.c | 8 hw/isa/vt82c686.c | 1 + 2

[PATCH v3 3/4] hw/isa/vt82c686: Route PIRQ inputs using via_isa_set_irq()

The chip has 4 pins (called PIRQA-D in VT82C686B and PINTA-D in VT8231) that are meant to be connected to PCI IRQ lines and allow routing PCI interrupts to the ISA PIC. Route these in via_isa_set_irq() to make it possible to share them with internal functions that can also be routed to the same
