Subject: [PATCH 54/73] libperf: Add perf_evlist_mmap_ops::idx callback
Date: Fri, 13 Sep 2019 15:23:36 +0200 [thread overview]
Message-ID: <20190913132355.21634-55-jolsa@kernel.org> (raw)
In-Reply-To: <20190913132355.21634-1-jolsa@kernel.org>
Adding perf_evlist_mmap_ops::idx callback to be called
in mmap_per_cpu and mmap_per_thread with current cpu and
thread indexes. It's used by current aux code, so perf
will used this callback to set aux index.
