TODO: the interrupt is firing only once:
Tested on Ubuntu 23.10:
sudo apt install binutils-riscv64-unknown-elf qemu-system-misc gdb-multiarch
cd riscv
make
Then on shell 1:
qemu-system-riscv64 -machine virt -cpu rv64 -smp 1 -s -S -nographic -bios none -kernel timer.elf
and on shell 2:
gdb-multiarch timer.elf -nh -ex "target remote :1234" -ex 'display /i $pc' -ex 'break *mtrap' -ex 'display *0x2004000' -ex 'display *0x200BFF8'
GDB should break infinitel many times on mtrap as interrupts happen.
