Subject: [PATCH V7 3/4] powerpc/perf: Support PERF_SAMPLE_DATA_PAGE_SIZE
Date: Thu, 17 Sep 2020 06:52:36 -0700	[thread overview]
Message-ID: <20200917135237.2857-4-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20200917135237.2857-1-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.
