Dear Linux kernel developpers,
I would like to ask you how to debug linux kernel over etherent.
We are designing aplication usaig RTAI (Hard realtime extension using kenrel
patch too) and we have been found some problems in our Linux kernel module.
This module serves a hard realime RTAI application and we are to debug it
using Ethernet insatead of RS232/RS485 or other UART port as is possible
out of box. We are familiar to use gdb as weel as for remote debuging of the
usewr space application but not debuging kernel.
Excuse me if I am sending messige to the wrong mailing list, please?
I look forward hearing from you
Yours faithfully

There's some traces of "kgdboe" in mainline code but I don't think
that feature was ever merged.

Perhaps you could google KGTP, and try to be another user of it.

Therefor I am not to find out kdboe anymore.

This is something like what we need as I see via first look

This is something that we need for another work.
Thank you one again for your help
Kind regards

Last time I used it, it was with 2.6.32. Patches are available there:
https://github.com/lacombar/linux-2.6/tree/v2.6.32-kgdboe
Port to 3.2 is trivial. I could get the connection, break into the
gdb, but failed to set breakpoints. I did not investigate further at
the time.
