Subject: [PATCH v2 0/3] perf/x86/amd/uncore: Update AMD uncore driver
Date: Mon, 16 Jan 2017 17:36:20 -0600 [thread overview]
Message-ID: <cover.1484598705.git.Janakarajan.Natarajan@amd.com> (raw)
This patchset updates the AMD uncore driver to support AMD Family17h processors.
First, the current L2 counters are renamed to Last level cache (LLC) counter to
reflect either L2 or L3 counters depending on the family. Next, the maximum
number of counters available is increased and the counters per uncore type is
now based on the family.
Also, in Family17h, the NorthBridge counters are re-purposed as Data Fabric (DF)
counters. Therefore, this patch exports the pmu name accordingly based on the
processor family.
v1->v2
* Removed dynamic memory allocation for counters, based on Peter Zijlstra's
feedback.
