Class Documentation

struct LAPIC::IPI::InterruptCommand.__unnamed62__

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.

Class Members
Register	value_low	First, low-order register.
Register	value_high	Second, high-order register.
