Hi all
i am doing some performance testing with FreeBSD (64 bit) and i would like =
to use pmcstat.
I recompiled the kernel with
options HWPMC_HOOKS
device hwpmc

When i restart the system looks like being ok

#sysctl -a | grep hwpmc
kern.hwpmc.nbuffers: 16
kern.hwpmc.logbuffersize: 4
kern.hwpmc.mtxpoolsize: 32
kern.hwpmc.nsamples: 32
kern.hwpmc.hashsize: 16

but the pmcstat gives me this error:

# pmcstat -s p6-hw-int-rx -w 1
pmcstat: ERROR: Initialization of the pmc(3) library failed: No such file o=
r directory

I googled a lot, but nothing about this problem. Consider that on the same =
hardware with 7.2-RELEASE 32 bit everything was working.
Anyone can help me?

This are some details:

uname -a
FreeBSD INTRUDER-64.ipv6.tilab.com 7.2-RELEASE FreeBSD 7.2-RELEASE #3: Thu =
Aug  6 11:36:53 CEST 2009    amd64
