3.3.1. tmux gem5
If you are using gem5 instead of QEMU, --tmux has a different effect by default: it opens the gem5 terminal instead of the debugger:
./run --emulator gem5 --tmux
To open a new pane with GDB instead of the terminal, use:
./run --gdb
which is equivalent to:
./run --emulator gem5 --gdb-wait --tmux --tmux-args start_kernel --tmux-program gdb
--tmux-program implies --tmux, so we can just write:
./run --emulator gem5 --gdb-wait --tmux-program gdb
If you also want to see both GDB and the terminal with gem5, then you will need to open a separate shell manually as usual with ./gem5-shell.
From inside tmux, you can create new terminals on a new window with Ctrl-B C split a pane yet again vertically with Ctrl-B % or horizontally with Ctrl-B ".
