Subject: [PATCH v2 2/6] perf evsel: Introduce an observed performance device
Date: Wed, 23 Dec 2020 16:03:16 +0300 [thread overview]
Message-ID: <20201223130320.3930-3-alexander.antonov@linux.intel.com> (raw)
In-Reply-To: <20201223130320.3930-1-alexander.antonov@linux.intel.com>
Adding evsel::perf_device void pointer.
For performance monitoring purposes, an evsel can have a related device.
These changes allow to attribute, for example, I/O performance metrics
to IIO stack.
