ARMv8 Baremetal Code with SMP Support
=====================================

This is a demo project for learning ARMv8 Aarch64 ISA and ARMv8 assembly.

It supports:

- [x] boot from EL1 & return to EL0
- [x] el1 vector table
- [x] stdio on uart
- [x] shell for EL0
- [x] svc demo
- [x] brk instructions & debug monitor shell in EL1
- [x] external debug (likely cpu<->jtag2usb<->usb_drvier<->gdbserver<->gdb)
- [x] [A64 exercises](https://developer.arm.com/documentation/102422/0100)
- [x] Calling convention demo
- [ ] SMP

It requires `qemu-system-aarch64` installed to run this project.

```bash
make run_elf_el1
```
