Message-ID: <1445859720-146146-2-git-send-email-wangnan0@huawei.com> Date: Mon, 26 Oct 2015 11:41:59 +0000 From: Wang Nan <wangnan0@...wei.com> To: <acme@...nel.org>, <ast@...mgrid.com>, <adrian.hunter@...el.com> CC: <linux-kernel@...r.kernel.org>, <pi3orama@....com>, <lizefan@...wei.com>, Wang Nan <wangnan0@...wei.com>, Arnaldo Carvalho de Melo <acme@...hat.com>, Peter Zijlstra <a.p.zijlstra@...llo.nl> Subject: [RFC PATCH v2 1/2] perf tools: Set evsel->system_wide field for global system wide recording evsel->system_wide is introduced by commit bf8e8f4b832972c76d64ab2e2837 (perf evlist: Add 'system_wide' option), which is used for mixing evsels that aren't system-wide with ones that are [1]. However, for global system wide recording (perf record -a ...), evsel->system_wide is set to false, which is confusion. This patch set evsel->system_wide to true if the target.system_wide is set, which makes evsel->system_wide a reliable way to describe whether itself is system_wide or not.
