Thanks

I believe it supports or cpu_type won't be mips/24K.


Once you setup session-dir in --setup you don't have to setup it
again. It's strange that you can issue 'opcontrol --dump
--session-dir=/var/lib/oprofile', on my x64 box, this command returns
'Option "--setup" not valid with "--dump"'.

what do you get if you 'cd /var/lib/oprofile/samples'?
