Struct Imsic

pub struct Imsic {}

The Incoming Message-Signalled Interrupt Controller (IMSIC) is a hardware component associated with a hart that coordinates incoming message-signalled interrupts (MSIs), and signals to the hart when pending interrupts need to be serviced.

Each IMSIC has a register file in memory for devices to write to (to trigger an interrupt), as well as a CSR interface for the hart to configure it via. There are separate interrupt files for each privilege level.
