+ SiFive SoCs and other RISC-V SoCs include an implementation of the
+ Platform-Level Interrupt Controller (PLIC) high-level specification in
+ the RISC-V Privileged Architecture specification. The PLIC connects all
+ external interrupts in the system to all hart contexts in the system, via
+ the external interrupt source in each hart.
A hart context is a privilege mode in a hardware execution thread. For example,
in an 4 core system with 2-way SMT, you have 8 harts and probably at least two
