2015-04-28scripts: add 'qemu coroutine' command to qemu-gdb.pyStefan Hajnoczi1-0/+75
The 'qemu coroutine <coroutine-address>' GDB command prints the backtrace for a CoroutineUContext. This is useful for peeking inside yielded coroutines that are waiting for file descriptor events, timers, etc. For example: $ gdb tests/test-coroutine (gdb) b test_yield (gdb) r (gdb) b qemu_coroutine_enter (gdb) c (gdb) c Continuing.

2012-03-24scripts: add gdb support scriptAvi Kivity1-0/+89
Add a script that enhances gdb to be aware of QEMU data structures. This patch adds a single gdb command, 'qemu mtree'. The command is similar to the monitor's 'info mtree', except that it prints MemoryRegion addresses, and except for working from a core dump as well as a live instance.
