QEMU-GDB Debugging

This extension provides a workflow for debugging QEMU using GDB.

Features

The extension prevents GDB being blocked by QEMU, so GDB can run as-is, and activate QEMU. It allows debugging in a VSCode session.

Tested on:

These settings can be specified:

qemu-gdb-debug.startQemuCommand: QEMU start command (Example: qemu-system-i386 -s -S -drive file=image.elf,index=0,if=floppy,format=raw)
qemu-gdb-debug.stopQemuCommand: QEMU stop command (can be omitted for not stopping) (Example: pkill -f qemu-system-i386)
qemu-gdb-debug.serverAddress: GDB server address (localhost:1234 by default in QEMU) (Example: localhost:1234)
qemu-gdb-debug.gdbPath: GDB path (Example: /usr/bin/gdb)
qemu-gdb-debug.executablePath: Executable path (generally same as the one QEMU runs) (Example: ${workspaceFolder}/bin/kernel.elf)

Debug with QEMU and GDB command is selected from the command palette (Ctrl + Shift + P).
