QEMU monitor in a separate terminal

[tuangu]

First of all, thanks for the great tutorial.
This is actually not an issue, but will help, at least for myself, easier to view registers/memory info, without overlapping with the kernel output.

# run.sh: add --monitor options
$QEMU -machine virt -bios default -nographic \
    -serial mon:stdio --monitor tcp:127.0.0.1:4321,server,nowait \
    --no-reboot \
    -d unimp,guest_errors,int,cpu_reset -D qemu.log \
    -kernel kernel.elf

# open another terminal
nc localhost 4321

Good advice, for me I use riscv32-buildroot-linux-gnu-gdb for kernel debugging, which gives me a more thorough understanding of how the program works and the memory layout.

I use tmux to divide it into three panes, the left one is the TUI mode of riscv32-buildroot-linux-gnu-gdb (which can be downloaded from here), which can be viewed using: help tui layout; the right side is divided into upper and lower panes: upper riscv32-buildroot-linux-gnu-objdump disassembles the source code, and qemu simulator output is below.
