Also if there some way to test Note, Daniel did start work on upstreaming this previously: http://lkml.kernel.org/r/1430388385-29558-1-git-send-email-daniel.wagner@bmw-carit.de There are a few things that do need to be cleaned up before this can go upstream. Please coordinate any effort with Daniel, if you want to get this rolling again. I'm not sure why the effort died last time. Could be because something more important came up. -- Steve > this throroughly on a board with a high resolution timer running mainline > (and not rt) kernel. > > Binoy > > Carsten Emde (1): > tracing: Add latency histograms > > Yang Shi (1): > trace: Add missing tracer macros > > Documentation/trace/histograms.txt | 186 ++++++ > include/linux/hrtimer.h | 3 + > include/linux/sched.h | 6 + > include/trace/events/hist.h | 74 +++ > include/trace/events/latency_hist.h | 136 +++++ > kernel/time/hrtimer.c | 20 + > kernel/trace/Kconfig | 104 ++++ > kernel/trace/Makefile | 4 + > kernel/trace/latency_hist.c | 1091 +++++++++++++++++++++++++++++++++++ > kernel/trace/trace_irqsoff.c | 9 + > 10 files changed, 1633 insertions(+) > create mode 100644 Documentation/trace/histograms.txt > create mode 100644 include/trace/events/hist.h > create mode 100644 include/trace/events/latency_hist.h > create mode 100644 kernel/trace/latency_hist.c > > -- > The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, > a Linux Foundation Collaborative Project
