Subject: [RFC V2 0/3] perf stat: improvements for handling of multiple PMUs
Date:   Fri,  2 Mar 2018 18:41:29 -0500
Message-Id: <1520034092-35275-1-git-send-email-agustinv@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This series of patches adds some simple improvements to the way perf stat
handles PMUs that have multiple instances by:

1. Adding glob-like matching in addition to the prefix-based matching
   introduced previously (patch 1).
2. Adding the ability to recover the PMU names when printing the events
   separately with the --no-merge option (patch 2).
3. Restoring auto-merge for events created by prefix or glob-like match
   (patch 3). Note that this still keeps the behavior that disables
   auto-merging of legacy symbolic events (e.g. cycles).

V2:

- Updated the documentation to explain prefix and glob matching of PMU
  names, and event auto-merging.
- Added sample output to the third patch.

Agustin Vega-Frias (3):
  perf, tools: Support wildcards on pmu name in dynamic pmu events
  perf, tools: Display pmu name when printing unmerged events in stat
  perf pmu: Auto-merge PMU events created by prefix or glob match
