You bet I was as I'm working on Moblin;-) However, some work while some
do not. I'll take a look at the problematic ones. With the previous
event and umask values, the pmc does not count at all for some events,
like l1d-write-ops.

Btw, one thing I don't quite understand is why you aliased
dtlb-write-ops to l1d-write-ops when setting event and umask values. Are
they the same event?

Thanks
