An update on perfmon and the struggle to get into the Linux kernel

At CHEP2007 we reported on the perfmon2 subsystem as a tool for interfacing to the PMUs (Performance Monitoring Units) which are found in the hardware of all modern processors (from AMD, Intel, SUN, IBM, MIPS, etc.). The intent was always to get the subsystem into the Linux kernel by default. This p...

Sumario:At CHEP2007 we reported on the perfmon2 subsystem as a tool for interfacing to the PMUs (Performance Monitoring Units) which are found in the hardware of all modern processors (from AMD, Intel, SUN, IBM, MIPS, etc.). The intent was always to get the subsystem into the Linux kernel by default. This paper reports on how progress was made (after long discussions) and will also show the latest additions to the subsystems.
