[Qemu-arm] [PATCH v2 13/15] gdbstub: gdb_set_stop_cpu: ignore request when process is not attached |
Date: |
Mon, 1 Oct 2018 13:57:02 +0200 |
When gdb_set_stop_cpu() is called with a CPU associated to a process
currently not attached by the GDB client, return without modifying the
stop CPU. Otherwise, GDB get confused if it receives packets with a
thread-id it does not know about.
