Hi, I'm using pfmon-3.4/libpfm-3.4 and kernel patch perfmon-new-base-080429 I've also tried pfmon-3.2/libpfm-3.2 with kernel patch perfmon-new-base-071017 and the cvs versions. All quit at the same point - pfm_load_context()
I doubt its a mismatch between the libpfm and the kernel versions as pfmon built on the same libpfm works fine. Its just with multiplex.c in the libpfm-examples (and specifically while monitoring system wide) Regards, Pradeep On Tue, Jul 22, 2008 at 11:52 PM, stephane eranian <[EMAIL PROTECTED]> wrote: > Pradeep, > > > On Fri, Jul 18, 2008 at 6:35 AM, Pradeep Rao <[EMAIL PROTECTED]> wrote: >> Hello, >> >> I have some trouble getting the multiplex.c example to run on my platform: >> kernel 2.6.25, Opteron model 254 >> >> Any idea what I'm missing ?
