Subject: [PATCH V8 3/4] powerpc/perf: Support PERF_SAMPLE_DATA_PAGE_SIZE
Date: Mon, 21 Sep 2020 08:26:52 -0700	[thread overview]
Message-ID: <20200921152653.3924-4-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20200921152653.3924-1-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

The new sample type, PERF_SAMPLE_DATA_PAGE_SIZE, requires the virtual
address. Update the data->addr if the sample type is set.
