To: perfctr-devel@lists.sourceforge.net Subject: perfctr-2.6.39 released Version 2.6.39 of perfctr, the Linux performance monitoring counters kernel extension, is now available at the usual place: http://user.it.uu.se/~mikpe/linux/perfctr/2.6/ Version 2.6.39, 2009-06-11 - Updated driver's AMD multicore detection code to actually work. Tested on Istanbul and Shanghai Opterons. - Updated driver to allow per-thread counting of Northbridge events on multicore AMD processors. Since the NB is shared between cores, threads counting NB events will be forced via their CPU affinity mask to core0 of the available processors. On early K8 RevE processors NB events remain limited to global-mode counting, due to an erratum. - Updated kernel support: 2.6.30, 2.6.29, 2.6.18-128.1.10.el5 (RHEL5), 2.6.18-92.1.26.el5 (RHEL5), 2.6.9-89.EL (RHEL4), 2.6.9-78.0.22.EL (RHEL4). / Mikael Pettersson (mikpe@acumem.com or mikpe@it.uu.se)
