From: Adrian Hunter Date: Tue, 6 Aug 2019 08:46:05 +0000 (+0300) Subject: perf tools: Add aux-output config term X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b9921546a9641aefc4a52c1c635b96b67142993;p=openwrt%2Fstaging%2Fblogic.git perf tools: Add aux-output config term Expose the aux_output attribute flag to the user to configure, by adding a config term 'aux-output'. For events that support it, selection of 'aux-output' causes the generation of AUX records instead of event records. This requires that an AUX area event is also provided.
