Thanks!

[PATCH v2] hw/intc: sifive_plic: Renumber the S irqs for numa support

2022-11-14 Thread Frédéric Pétrot
Commit 40244040a7a changed the way the S irqs are numbered. This breaks when
using numa configuration, e.g.:
./qemu-system-riscv64 -nographic -machine virt,dumpdtb=numa-tree.dtb \
  -m 2G -smp cpus=16 \
  -object memory-backend-ram,id=mem0,size=512M \
  -object memory-backend-ram,id=mem1,size=512M \
  -object memory-backend-ram,id=mem2,size=512M \
  -object memory-backend-ram,id=mem3,size=512M \
  -numa node,cpus=0-3,memdev=mem0,nodeid=0 \
  -numa node,cpus=4-7,memdev=mem1,nodeid=1 \
  -numa node,cpus=8-11,memdev=mem2,nodeid=2 \
  -numa node,cpus=12-15,memdev=mem3,nodeid=3
leads to:
Unexpected error in object_property_find_err() at ../qom/object.c:1304:
qemu-system-riscv64: Property 'riscv.sifive.plic.unnamed-gpio-out[8]' not
found

This patch makes the nubering of the S irqs identical to what it was before.
