Platform-Level Interrupt Controller (PLIC)

The specification of CVA6’s platform-level interrupt controller (PLIC) is aligned with the PLIC of SiFive’s FU540-C000. It shares the same functionality and memory map and has the following interrupt sources:

Interrupt ID	Source
1	UART
2	SPI
3	Ethernet
4	Timer 0 (OVF)
5	Timer 0 (CMP)
6	Timer 1 (OVF)
7	Timer 1 (CMP)
8 – 30	Reserved
