2023-05-15hw/loongarch/virt: Set max 256 cpus support on loongarch virt machineSong Gao1-2/+2
Add separate macro EXTIOI_CPUS for extioi interrupt controller, extioi only supports 4 cpu. And set macro LOONGARCH_MAX_CPUS as 256 so that loongarch virt machine supports more cpus. Interrupts from external devices can only be routed cpu 0-3 because of extioi limits, cpu internal interrupt such as timer/ipi can be triggered on all cpus.

2022-11-04hw/intc: Fix LoongArch extioi coreisr accessingXiaojuan Yang1-4/+6
1. When cpu read or write extioi COREISR reg, it should access the reg belonged to itself, so the cpu index of 's->coreisr' is current cpu number. Using MemTxAttrs' requester_id to get the cpu index. 2. it need not to mask 0x1f when calculate the coreisr array index.
