[PATCH v2 0/4] hw/loongarch/virt: Set iocsr address space per-board rather percpu

Posted by Bibo Mao 1 year, 11 months ago

On LoongArch system, there is iocsr address space simliar system io
address space on x86. And each cpu has its separate iocsr address space now,
with this patch, iocsr address space is changed with per-board, and
MemTxAttrs.requester_id is used to differentiate cpu cores.

---
Changes in v2:
  1. Add num-cpu property for extioi interrupt controller
  2. Add post_load support for extioi vmstate to calculate sw_ipmap/sw_coremap info
---
Bibo Mao (4):
  hw/intc/loongarch_ipi: Use MemTxAttrs interface for ipi ops
  hw/loongarch/virt: Set iocsr address space per-board rather than
    percpu
  hw/intc/loongarch_extioi: Add dynamic cpu number support
  hw/intc/loongarch_extioi: Add vmstate post_load support

Applied to loongarch-next.

Thanks.
