Implementations§

Source§

impl MadtInfo

Source

pub fn irq_to_gsi(&self, irq: u8) -> (u32, u8, u8)

Look up an IRQ’s GSI and polarity/trigger, applying source overrides.

Returns (gsi, polarity, trigger_mode) for the given legacy IRQ. If no override exists, returns (irq as gsi, 0 = conform, 0 = conform).
