LAPIC::IPI::InterruptCommand.__unnamed43__

struct LAPIC::IPI::InterruptCommand.__unnamed43__

I/O redirection-table entry.

Every entry in the redirection table represents an external source of interrupts and has a size of 64 bits. Due to the I/O APIC registers being only 32 bits wide, the 64-bit value is split in two 32 bit values.
