I saw a file 'lava-dispatcher/actions/boot/gdb.py' in the LAVA source code, which seems to define a gdb method in action->boot. But I didn't find a description of it in the LAVA documentation. The document I checked is `https://docs.lavasoftware.org/lava/actions-boot.html?highlight=boot#boot-act.... Reading the source code may lead to some misunderstandings and is time-consuming. I hope someone who knows its function can explain to me what this new method does. Thank you very much!
