Debugging with VNC

How to use on Fedora Asahi Remix 40:

1. Enable QEMU's VNC support
   1. Install dependencies
      • sudo dnf install pixman-devel
   2. Build QEMU again with VNC enabled
      1. Download source code
      2. tar xvf <downloaded .tar.xz file>
      3. cd <extracted directory>
      4. ./configure --enable-vnc
      5. make -j8
      6. sudo make install
2. Run QEMU
   1. Change the current directory to swift_os
   2. Modify Makefile (or you can use SSH port forwarding using a SSH client app (e.g. Blink Shell))

      -       $(QEMU) -machine raspi4b -kernel $(IMG) -serial stdio
      +       $(QEMU) -machine raspi4b -kernel $(IMG) -serial stdio -display vnc=0.0.0.0:0

   3. Run make run
3. Connect to <IP address>:5900 from a VNC client (e.g. Screens or RealVNC Viewer)
