To: perfctr-devel@lists.sourceforge.net Subject: perfctr-2.6.0-pre1 released Cc: linux-kernel@vger.kernel.org Version 2.6.0-pre1 of perfctr, the Linux/x86 performance monitoring counters driver, is now available at the usual place: http://www.csd.uu.se/~mikpe/linux/perfctr/ After this there will be one or more further -pre versions with changes to the kernel/user-space API, which are needed to ensure binary compatibility between x86 and x86-64, and to permit future extensions without breaking ABIs. Version 2.6.0-pre1, 2003-07-02 - Rearranged the data structure holding the counter state to reduce the number of caches lines needed to be touched at key operations. The new representation is also binary compatible between x86 and x86-64, which matters since user-space mmaps() it. - Added RPM spec file for the library. (From Bryan O'Sullivan). - Patch kit updated for kernels 2.4.22-pre2 and 2.5.73. / Mikael Pettersson
