From 880860e392d92c457e8116cdee39ec4d109174ee Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 6 Mar 2009 16:30:52 +1100 Subject: perfcounters/powerpc: add support for POWER4 processors Impact: more hardware support This adds the back-end for the PMU on the POWER4 and POWER4+ processors (GP and GQ). This is quite similar to the PPC970, with 8 PMCs, but has fewer events than the PPC970.
