Subject: [PATCH 24/25] perf c2c: Fix report with offline cpus
Date: Thu, 22 Aug 2019 18:00:59 -0300 [thread overview]
Message-ID: <20190822210100.3461-25-acme@kernel.org> (raw)
In-Reply-To: <20190822210100.3461-1-acme@kernel.org>
From: Ravi Bangoria <ravi.bangoria@linux.ibm.com>
If c2c is recorded on a machine where any cpus are offline, 'perf c2c
report' throws an error "node/cpu topology bugFailed setup nodes".
It fails because while preparing node-cpu mapping we don't consider
offline cpus.

Acked-by: Jiri Olsa <jolsa@kernel.org>
Fixes: 1e181b92a2da ("perf c2c report: Add 'node' sort key")
