From a06148024dc3cac17fcfd31aa856d833282eb484 Mon Sep 17 00:00:00 2001 From: bob picco Date: Tue, 16 Sep 2014 10:09:06 -0400 Subject: sparc64: T5 PMU The T5 (niagara5) has different PCR related HV fast trap values and a new HV API Group. This patch utilizes these and shares when possible with niagara4. We use the same sparc_pmu niagara4_pmu. Should there be new effort to obtain the MCU perf statistics then this would have to be changed. Cc: sparclinux@vger.kernel.org Signed-off-by: Bob Picco Signed-off-by: David S.
