Struct MadtIso 

Source 
pub struct MadtIso {
    pub bus: u8,
    pub irq_source: u8,
    pub gsi: u32,
    pub flags: u16,
}
Expand description

Interrupt Source Override entry from the MADT.

Maps ISA IRQ numbers to their actual GSI (Global System Interrupt) numbers with polarity and trigger mode overrides.

Fields§

§bus: u8

Bus source (always 0 = ISA).

§irq_source: u8

ISA IRQ number being overridden.

§gsi: u32

Global System Interrupt number this IRQ maps to.

§flags: u16

Flags: bits 1:0 = polarity, bits 3:2 = trigger mode.
