If you're interested in ltrace, you may want to take a look at the
Linux trace toolkit (http://www.opersys.com/LTT). It runs fine
on PPC too.

I'm *very* interested in any toolkit that can provide point-to-point
_timing_ of system calls, IRQ handling, system usage. latency etc. etc. (a
la TIMEPEGS or Andrew Morton's amlat on x86).

what do we have (existing) on PPC?

I did an IRQ latency thing on 2.2.x and Cort has proposed using RTlinux to
make IRQ measurements (well, I think he's done it, actually)...  that will
give headlines - but not tell us which drivers/functions are the rouges.

I was considering doing a port of Andrew Morton's stuff - but got stuck when
I tried to run with HZ=1024 - it trashed adb... and I haven't got back to it
yet.

What about SGI's Kernprof stuff? <http://oss.sgi.com/projects/kernprof/>.

I was going to poke at it to see if/what it breaks a while back when there
was some talk of weird SMP slowdowns, but I think I got sidetracked with
something else.

Anyways, it's probably worth looking into.
