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 hw/intc/loongarch_extioi.c | 230 ++++++++++++++++++----------- hw/intc/loongarch_ipi.c | 191 +++++++++++++++--------- hw/loongarch/virt.c | 94 ++++++++---- include/hw/intc/loongarch_extioi.h | 12 +- include/hw/intc/loongarch_ipi.h | 3 +- include/hw/loongarch/virt.h | 3 + target/loongarch/cpu.c | 48 ------ target/loongarch/cpu.h | 4 +- target/loongarch/iocsr_helper.c | 16 +- 9 files changed, 358 insertions(+), 243 deletions(-) base-commit: 039afc5ef7367fbc8fb475580c291c2655e856cb
