Subject: [PATCH 1/3] perf vendor events intel: Metric fixes for SKX/CLX
Date:   Fri, 28 Jun 2019 15:07:35 -0700
Message-Id: <20190628220737.13259-1-andi@firstfloor.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Andi Kleen <ak@linux.intel.com>

- Add a missing filter for the DRAM_Latency / DRAM_Parallel_Reads metrics
- Remove the useless PMM_* metrics from Skylake
