Thank you, Fabien! The patch is linked to from the PmcTools wiki page: http://wiki.freebsd.org/PmcTools. The current file name is: "patch-callchain-FreeBSD-7-STABLE-2008-07-12.gz". As the file name indicates, it should apply against a 7-STABLE tree of 2008-07-12 vintage. To apply the patch: % cd /home/src-7x # or whereever your RELENG_7 tree resides % patch < PATCH-FILE Then you should follow the full procedure to update userland and kernel from source as spelled out in src/UPDATING. Please note that HWPMC(4) log files that contain callchain information are not binary compatible with prior versions of pmc(3) and pmcstat(8). Please do test on your systems and let Fabien and me know how you fared. Koshy
