LPC Programmable Interrupt Controller (LPC PIC) Structure

LPC PIC (Low Pin Count Programmable Interrupt Controller) is responsible for handling ISA IRQs of old legacy devices such as PS/2 mouse, keyboard and UARTs for Loongarch machines.

Fields

type: u8

23 - LPC Programmable Interrupt Controller Structure

length: u8

Length of the LPC Programmable Interrupt Controller Structure in bytes.

JJ’s Note: There doesn’t seem to be any variable-sized fields in this struct. The size is 15 bytes…

version: u8

• 0x00 - Invalid
• 0x01 - LPC PIC v1

Other values are reserved.

base_address: u64

The base address of LPC PIC registers.

size: u16

The register space size of LPC PIC.

cascade_vector: u16

This field described routed vector on BIO PIC from LPC PIC vectors.
