[PATCH v8 21/23] hw/riscv: virt: Add optional AIA IMSIC support to virt machine

2022-01-19 Thread Anup Patel
From: Anup Patel We extend virt machine to emulate both AIA IMSIC and AIA APLIC devices only when "aia=aplic-imsic" parameter is passed along with machine name in the QEMU command-line. The AIA IMSIC is only a per-HART MSI controller so we use AIA APLIC in MSI-mode to forward all wired interrupts
