# aarch64 Rust OS demo

An example of combining various libraries for aarch64 OS development in Rust.

This crate demonstrates how to use a number of aarch64-specific crates:

- `aarch64-paging` for page table management.
- `aarch64-rt` for the entry point and exception handling.
- `arm-sysregs` for accessing system registers.
- `smccc` for PSCI and other standard SMC calls to EL3 firmware.

As well as some more general crates for embedded development:

- `buddy_system_allocator` for heap allocation.
- `dtoolkit` for device tree parsing.
- `percore` for exception masking.

And some device driver crates:

- `arm-gic` for the Arm Generic Interrupt Controller.
- `arm_pl031` for the PL031 real-time clock.
- `arm-pl011-uart` for the PL011 UART.
- `uart_16550` for the 16550 UART.
- `virtio-drivers` for various VirtIO devices.
