[PATCH 0/2] hw/riscv: Make virt AIA setup reusable

Posted by Joel Stanley 1 month ago

Sharing the AIA setup code looked like a good idea when I was
implementing a machine with AIA. It will be used by Atlantis initially.

Atlantis will use 128 IRQ sources so the second patch makes that
configurable as part of the setup. I initially changed it globally and
that broke the virt acpi tests as the number is encoded in acpi
blob.

  hw/riscv/virt: Move AIA initialisation to helper file
  hw/riscv/aia: Provide number of irq sources
