[Qemu-devel] [PATCH v1 1/1] gdbserver: Keep VM state status replies from happening during a syscall |
Date: |
Wed, 15 Feb 2012 10:55:14 -0600 |
Fix an issue where the GDB server implementation was allowing 'RUN_STATE_DEBUG'
transitions to send a signal trap status back to the GDB client while a syscall
is being processed. This eventually resulted in sending a SIGINT to the GDB
client.
