We assume the PLIC is currently the only global interrupt controller that RISC-V platforms are going to use. Each platform may have a different programmers model for interracting with the hardware controller. We provide a common interface for PLIC drivers to implement that the kernel will use to manage IRQs. Also authored by: Siwei Zhuang <siwei.zhuang@data61.csiro.au> |
