Title:
[ubuntu 16.10] Enable perf to probe and record on SDT events present
in binaries
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Yakkety:
In Progress
Bug description:
This is a feature request for 16.10:
SDT events are markers placed at important places in the binaries.
When they are probed and traced, they can give valuable information
about the userspace application. This feature aims to enable perf to
probe/record on SDT events.
Patches are being currently sent :
https://lkml.org/lkml/2016/5/14/107 patchset for probe-cache and initial SDT support
https://lkml.org/lkml/2016/5/3/810 patch to directly record on SDT events.
