This is the official performance monitoring interface now. It is available by default since 2.6.31. If you grab 2.6.34, you will get model 46 support right away. As for the perf_event tool, it is also in the kernel source tree (tools/perf). ------------------------------------------------------------------------------ _______________________________________________ perfmon2-devel mailing list perfmon2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/perfmon2-devel
