Hi,
Here is the 4th version of the patchset for probe-cache and
initial SDT support which are going to be perf-cache finally.
Applied your patches and tested them. I have a few questions/
suggestions on some of the patches.
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.
Thank you,
