Restart remote target machine with gdb
原标题:

I m debugging a Mac OS X kernel via a remote target (target remote-kdp) when it gets into a kernel panic. I can introspect the state of the machine at the time, but if I need to restart the machine I have to do a hard power down, which involves direct physical access. This means I can t script introspecting kernel panics.

Is it possible to ask a kernel, once it s in a panic, to do a hard reset? It s a Mac Mini on i386 if that s any help; obviously, since it s in a panic, I can t log in or do shutdown or similar; but I wonder if there s some kind of assembly call or reboot command that I can use to ask the machine to restart?

最佳回答

I discovered that there s a GDB command kdp-reboot which will bounce a machine that s in a panic state, and bring it back up again.
