Subject: [PATCH v2 0/3] perf bench numa: make possible testing on uneven and/or overlapping CPU ranges
Date: Mon, 10 Aug 2020 08:21:57 +0200 [thread overview]
Message-ID: <cover.1597004831.git.agordeev@linux.ibm.com> (raw)
This series allows running the tool on some configurations
that do not conform to an assumption each node contains
nr_cpus/nr_nodes CPUs at most. Instead, the actual node-to-
CPU mapping is acquired dynamically.
patch 1 fixes the described issue
patches 2,3 are follow-up fixes
Changes since v1:
- numa01* and numa02* test names left intact;
- "2x3-convergence" fix moved out to separate patch
