Subject: [dpdk-dev] [PATCH] doc: improve lstopo tip
Date: Mon,  8 Mar 2021 23:25:52 +0100	[thread overview]
Message-ID: <20210308222553.823262-1-thomas@monjalon.net> (raw)

The tool lstopo from hwloc package can provide a graphical
or textual view.
In its textual form, the option --merge gives a shorter summary
which fits well with the DPDK need.
