To: perfctr-devel@lists.sourceforge.net Subject: perfctr-2.6.25 released Version 2.6.25 of perfctr, the Linux performance monitoring counters kernel extension, is now available at the usual place: http://www.csd.uu.se/~mikpe/linux/perfctr/2.6/ Version 2.6.25, 2006-10-15 - The Intel Core 2 processors are substantially different from the old Core processors. Core 2 processors are now mapped to a new cpu_type PERFCTR_X86_INTEL_CORE2, and must be programmed so that every EVNTSEL used has its Enable flag set. This is consistent with Intel's documentation and observations made by others on later steppings of the Core 2. Early steppings may be more P6-like (master Enable in EVNTSEL0), but as long as a control setup includes EVNTSEL0 it should work on any stepping. - Major x86 driver updates for changes in kernel 2.6.19-rc1. - Updated kernel support: 2.6.19-rc2, 2.6.18, 2.6.9-42.0.3.EL (RHEL4), and 2.4.34-pre4. - Fixed perfex -l/-L to handle unavailability of event set data gracefully and not signal an error in those cases. / Mikael Pettersson
