Anyone tried SystemTap on the Cell BE?

Anyone tried SystemTap on the Cell BE?

[Nathan DeBardeleben]

I've been using SystemTap for a while now on some standard Fedora 
machines but am starting some new work on some Cell Broadband Engine 
machines and was wondering if anyone has anything to report about 
SystemTap and kprobes on this processor.  As I gather I'll need to use a 
kernel.org kernel patched with Cell-specific bits that haven't yet found 
their way into the main-line kernel yet.  So that means no nice yumming 
of the debuginfo package.

Surely with the companies involved in SystemTap there would have been 
some effort in this direction by now on the Cell.  I'm curious if 
anyone's found some particularly fun probe points or problems getting it 
to work.

Thanks!

Hi Nathan,

To my knowledge no one has tried kprobes on Cell processor and i don't 
even know if it works.
