7 title: RISC-V Hart-Level Interrupt Controller (HLIC)
10 RISC-V cores include Control Status Registers (CSRs) which are local to
11 each CPU core (HART in RISC-V terminology) and can be read or written by
16 The RISC-V supervisor ISA manual specifies three interrupt sources that are
19 cores. The timer interrupt comes from an architecturally mandated real-
22 the HLIC, which are routed via the platform-level interrupt controller
