Remote logging over regular remote protocol

Remote logging over regular remote protocol

[Bogdan Harjoc]

Hello,

Do remote stubs have the ability to send logging messages to the gdb console ?
I am trying to debug a Darwin target and seeing the dmesg (or similar)
output would
be useful. The stub Darwin uses for gdb works over ethernet and I
can't figure out
how to direct the dmesg output to the host I'm debugging from (there
is no serial
port either since it's a Mac, so no serial console as far as I can tell).

The "Remote serial protocol" manual section suggests notification packets would
be usable for this, but "Stop: reply" is the only such packet type listed.

Has someone already done this ? Or am looking at it the wrong way ? Syslog's
remote capabilities seem overkill here.

Thanks,
Bogdan

Perhaps you're looking for the `O' packet?

<http://sourceware.org/gdb/current/onlinedocs/gdb/Stop-Reply-Packets.html#Stop-Reply-Packets>

`O XX...'
    `XX...' is hex encoding of ascii data, to be written as the program's console output. This can happen at any time while the program is running and the debugger should continue to wait for `W', `T', etc. This reply is not permitted in non-stop mode.
