# Arm Generic Interrupt Controller driver
[](https://crates.io/crates/arm-gic)
[](https://docs.rs/arm-gic)
This crate provides Rust drivers for the Arm Generic Interrupt Controller version 2, 3 or 4 (GICv2,
GICv3 and GICv4) on aarch32 and aarch64.
Because of large technical differences between the version 2 and version 3/4 Generic Interrupt
Controllers, they have been separated in different modules. Use the one appropriate for your
hardware. The interfaces are largely compatible. Only differences when dispatching
software-generated interrupts should be considered. Look at the ARM manuals for further details.
