Subject: [PATCH V2 03/12] perf script: Support data page size
Date: Wed, 23 Jan 2019 07:15:21 -0800 [thread overview]
Message-ID: <1548256530-10065-3-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1548256530-10065-1-git-send-email-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
Display the data page size if it is available.
Can be configured by the user, for example:
perf script --fields comm,event,phys_addr,data_page_size
