Core Programmable Interrupt Controller (CORE PIC) Structure

Each processor in Loongarch system has a Core Programmable Interrupt Controller record in the MADT, and a processor device object in the DSDT.

Fields

type: u8

17 - Core Programmable Interrupt Controller Structure

length: u8

Length of the Core 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 - CORE PIC v1

Other values are reserved.

acpi_processor_id: u32

The OS associates this CORE PIC Structure with a processor device object in the namespace when the _UID child object of the processor device evaluates to a numeric value that matches the numeric value in this field.

phsyical_processor_id: u32

The processor core physical id.

0xFFFFFFFF is invalid value.

If invalid, this processor is unusable, and OSPM shall ignore Core Interrupt Controller Structure.

flags: COREPICFlags

CORE PIC flags.
