have not heard of such feature available, but technically, the reason why
serial port is important is because it is initialized at a very early stage
in linux kernel bootup, and anything that happened before that cannot be
analyzed via kgdb as well.   i am not sure why u need ethernet.   normally
my approach is to use VirtualBox running a kernel with kgdb parameters all
setup, and then define a virtual serial port in VirtualBox, to connect to a
pipe, and then from host OS, use gdb to attach via "target remote" to the
virtual terminal, which is created via the "socat" command.

Search the web for details.

Please let me know if you have some other information.

Subject: kgdb over ethernet support for 3.x kernel

Hi ,

3.x kernel does not seem to have built in support to use kgdb over
ethernet functionality .
To use this , can i be guided from where i can download patch for the
same and apply to 3.x series kernel ?

thanx & regards
Amit Nagal

Actually i want to to debug kernel modules with kgdb - gdb connected
over tcp / udp port
as depicted in
http://kernel.org/pub/linux/kernel/people/jwessel/kdb/EnableKGDB.html
section 3 .
but in kernel , there seems to no built in support for that .

Thanx & Regards
Amit Nagal
