Hi, Here is the 4th version of the patchset for probe-cache and initial SDT support which are going to be perf-cache finally.
The previous version is here; https://lkml.org/lkml/2015/8/15/52 This version fixes some bugs and improve wildcard support ( including automatic target binary selection, we don't need -x option for SDT/pre-cached events any more :) ), and drops perf-record support currently because it seems more work on cleanup side. BTW, since I couldn't find list_dir function in Arnaldo's mail, so this series still have a patch to add lsdir(). Note that all SDT events have "sdt_" prefix on the provider name, because of easier to distinguish between other named caches. TODOs: - (perf record) Support SDT event recording directly - (perf record) Support @FILE/@BUILDID suffix to record specific SDTs. - (perf record) Try to unregister SDT events after record. - (ftrace) Support multiple SDTs on single event. Done: - (perf probe) Allow glob matching for pre-cached events. - (perf probe) Removes -x option when using pre-cached events. - (perf probe) Support @FILE/@BUILDID suffix for pre-cached events. - (perf buildid-cache) Fallback to old style buildid-cache.
