8 title: SiFive Platform-Level Interrupt Controller (PLIC)
11 SiFive SoCs and other RISC-V SoCs include an implementation of the
12 Platform-Level Interrupt Controller (PLIC) high-level specification in
13 the RISC-V Privileged Architecture specification. The PLIC connects all
18 in an 4 core system with 2-way SMT, you have 8 harts and probably at least two

2 ---------------------------------------------
4 RISC-V cores include Control Status Registers (CSRs) which are local to each
5 CPU core (HART in RISC-V terminology) and can be read or written by software.
10 The RISC-V supervisor ISA manual specifies three interrupt sources that are
13 timer interrupt comes from an architecturally mandated real-time timer that is
16 via the platform-level interrupt controller (PLIC).
18 All RISC-V systems that conform to the supervisor ISA specification are

23 a PLIC interrupt property will typically list the HLICs for all present HARTs
