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. ciao, Iain ** Sent via the linuxppc-dev mail list.
