Subject: [PATCH v3 0/6] powerpc/perf: Export memory hierarchy level
Date: Thu, 23 Mar 2017 08:56:02 +0530 [thread overview]
Message-ID: <1490239568-30429-1-git-send-email-maddy@linux.vnet.ibm.com> (raw)
Power8/Power9 Perforence Monitoring Unit (PMU) supports
different sampling modes (SM) such as Random Instruction
Sampling (RIS), Random Load/Store Facility Sampling (RLS)
and Random Branch Sampling (RBS). Sample mode RLS updates
Sampled Instruction Event Register [SIER] bits with memory
hierarchy information for a cache reload. Patchset exports
the hierarchy information to the user via the perf_mem_data_src
object from SIER.
Patchset is a rebase of the work posted previously with minor
updates to it.

Changelog v2:
-Updated the commit messages

Changelog v1:
- Fixed author-ship for the first patch and added suka's "Signed-off-by:".
