[PATCH 08/22] perf powerpc: Support CPU ID matching for Powerpc

Show all headers | View raw

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>

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.
