Extend I/O Programmable Interrupt Controller (EIO PIC) Structure

In newer generation Loongson CPUs, Extend I/O Programmable Interrupt Controller (EIO PIC) replaces the combination of HT PIC and part of LIO PIC, and routes interrupts from BIO PIC and MSI PIC to CORE PIC directly.

Fields

type: u8

20 - Extend I/O Programmable Interrupt Controller Structure

length: u8

Length of the Extend I/O 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 13 bytes…

version: u8

• 0x00 - Invalid
• 0x01 - EIO PIC v1

Other values are reserved.

cascade_vector: u8

This field describes routed vector on CORE PIC from EIO PIC vectors.

node: u8

The node ID of the node connected to bridge.

node_map: u64

Each bit indicates one node that can receive interrupt routing from the EIO PIC.
