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

Posted by Joel Stanley 3 weeks, 5 days ago

v2: Add assert for number of irq sources

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.

I forgot to set V2 in the subject when sending this series. My
apologies, it's been a while between patches.

Let me know if a re-send would help.

Cheers,

Joel
