armvisor

simple bare-metal armv8 (aarch64) hypervisor for learning purposes.

• vm, vcpu arch
• stage 2 address translation
• hypervisor interrupts, gicv3
• timer (el2, el1), uart

environment

• qemu-system-aarch64
• arm toolchain: aarch64-linux-gnu
• gdb-multiarch

hello vm 1

for debugging

> make debug
$ gdb target remote localhost:1234

to-do

• [] hypervisor: loader should be changed
• [] hypervisor: virtual interrupt routing
• [] debugging: dump guest memory
