To: perfctr-devel@lists.sourceforge.net Subject: perfctr-2.4.0-pre2 released perfctr-2.4.0-pre2 is now available at the usual place: http://www.csd.uu.se/~mikpe/linux/perfctr/ Note that there is a binary incompatible change in this release. Version 2.4.0-pre2, 2002-08-27 - vperfctr_control() now allows the user to specify that some PMC sums are not to be cleared when updating the control. There is a new bitmap field `preserve' in struct vperfctr_control: if bit i is set then PMC(i)'s sum is not cleared. `preserve' is a simple `unsigned long' for now, since this type fits all currently known CPU types. This change breaks binary compatibility, but user-space code which clears the entire control record before filling in relevant fields will continue to work as before after a recompile. This feature removes a limitation which some people felt was a problem for some usage scenarios. / Mikael Pettersson
