This series allows leon3 emulations to record up 4 CPUs. It requires some enhancements in the grlib_irqmp device and adding the cpu_index field in the asr17 instruction.
It has been tested locally with various bareboard runtimes and through the Gitlab CI: https://gitlab.com/Helflym/qemu/-/pipelines/1127834623.
