From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andi Kleen Subject: [PATCH v6 05/11] perf tools report: Support running scripts for current time range Date: Mon, 11 Mar 2019 07:44:56 -0700 Message-ID: <20190311144502.15423-6-andi@firstfloor.org> References: <20190311144502.15423-1-andi@firstfloor.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20190311144502.15423-1-andi@firstfloor.org> Sender: linux-kernel-owner@vger.kernel.org To: acme@kernel.org Cc: jolsa@kernel.org, linux-perf-users@vger.kernel.org, linux-kernel@vger.kernel.org, Andi Kleen List-Id: linux-perf-users.vger.kernel.org From: Andi Kleen When using the time sort key, add new context menus to run scripts for only the currently selected time range. Compute the correct range for the selection add pass it as the --time option to perf script.
