            Bug ID: 27439
           Summary: Detection of a running target/process
           Product: gdb
           Version: 8.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb

  Target Milestone: ---

Perhaps more of a question (sorry if on the wrong list!).=20

As i understand it the RSP-protocol has the "stop reply" packets used by an
RSP-stub/GDB-server to inform GDB-client that my debug target has stopped. =
But
i cant find any information if its possible for an RSP-stub/GDB-server to
inform the GDB-client if my debug target starts to execute by some external
event not controlled by the GDB-client itself.

For example:
* During a GDB session (target halted) i repower/reset an development board=
 and
the process starts to execute. Can GDB be notified about this?

* In a heterogeneous multi-core scenario where the starting/stopping of the
cores are controlled by ARM cortex-M Cross Triggering. Different cores are
controlled by multiple GDB-sessions. Perhaps the same issue as above. One
GDB-session needs to get notified that the debug target started to execute.

Anyone know if there exists some RSP support for this. Some sort of "Running
reply"?

Best Regards
Anders Jansson
