[PATCH v18 04/19] perf, tools: Support CPU ID matching for Powerpc

From: Sukadev Bhattiprolu
Date: Mon Oct 26 2015 - 16:23:06 EST


Implement code that returns the generic CPU ID string for Powerpc.
This will be used to identify the specific table of PMU events to
parse/compare user specified events against.
