Subject: [PATCH 00/22] perf tools: Add traceevent plugins support
hi,
backporting traceevent plugin support from trace-cmd.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
Initial RFC is here:
http://marc.info/?l=linux-kernel&m=137803257921043&w=2
Having plugins allow traceevent to properly parse 'print fmt'
line of tracepoint format and display proper/additional data
in perf script command (check examples below).
Plugins backported from trace-cmd:
plugin_function.c
plugin_hrtimer.c
plugin_jbd2.c
plugin_kmem.c
plugin_kvm.c
plugin_mac80211.c
plugin_sched_switch.c
Plugins newly added:
plugin_cfg80211.c
plugin_scsi.c
plugin_xen.c
Changes from RFC:
- added comment about repo/HEAD of the backport source
- ommited options plugin support
- change plugins installation path to:
$(perfexecdir)/traceevent/plugins
The code is available in here:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/core_plugins
thanks,
jirka
