Subject: [PATCH v6 06/12] perf tools: drop in cpu_aggr_map struct
Date: Thu, 26 Nov 2020 16:13:22 +0200
Message-ID: <20201126141328.6509-7-james.clark@arm.com> (raw)
In-Reply-To: <20201126141328.6509-1-james.clark@arm.com>

Replace usages of perf_cpu_map with cpu_aggr map in
places that are involved with perf stat aggregation.

This will then later be changed to be a map of
cpu_aggr_id rather than an int so that more data can
be stored.

No functional changes.
