see enclosed patch that also enables Barcelona cores. I have tested
your releases on K8 and Barcelona. 2.6.21 release
(perfmon-new-base-070509) works fine. In 2.6.22-rc3 syscalls seems to
be broken. I receive a EBADF error when trying to create a context. It
seems that sys_pfm_create_context() is never called. I could not yet
dig into this deeper.
There are also patches available for new family 10 features. I will
release these patches next week. I already implemented a generic AMD64
PMU description that detects features for different families and CPU
revisions. Enclosed patch is part of the patch series.
