[PATCH v1 0/2] 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.
