-Subject: perf evlist: Add evlist__add_dummy_on_all_cpus()
-
-From: Adrian Hunter <adrian.hunter@intel.com>
-
-[ Upstream commit 126d68fdcabed8c2ca5ffaba785add93ef722da8 ]
-
-Add evlist__add_dummy_on_all_cpus() to enable creating a system-wide dummy
-event that sets up the system-wide maps before map propagation.
-
-For convenience, add evlist__add_aux_dummy() so that the logic can be used
-whether or not the event needs to be system-wide.

-Subject: perf evlist: Avoid frequency mode for the dummy event
-
-From: Ian Rogers <irogers@google.com>
-
-[ Upstream commit f9cdeb58a9cf46c09b56f5f661ea8da24b6458c3 ]
-
-Dummy events are created with an attribute where the period and freq
-are zero. evsel__config will then see the uninitialized values and
-initialize them in evsel__default_freq_period. As fequency mode is
-used by default the dummy event would be set to use frequency
-mode. However, this has no effect on the dummy event but does cause
-unnecessary timers/interrupts. Avoid this overhead by setting the
-period to 1 for dummy events.
-
-evlist__add_aux_dummy calls evlist__add_dummy then sets freq=0 and
-period=1. This isn't necessary after this change and so the setting is
-removed.
-
-From Stephane:
-
-The dummy event is not counting anything. It is used to collect mmap
-records and avoid a race condition during the synthesize mmap phase of
-perf record. As such, it should not cause any overhead during active
-profiling. Yet, it did. Because of a bug the dummy event was
-programmed as a sampling event in frequency mode. Events in that mode
-incur more kernel overheads because on timer tick, the kernel has to
-look at the number of samples for each event and potentially adjust
-the sampling period to achieve the desired frequency. The dummy event
-was therefore adding a frequency event to task and ctx contexts we may
-otherwise not have any, e.g.,
-
- perf record -a -e cpu/event=0x3c,period=10000000/.
-
-On each timer tick the perf_adjust_freq_unthr_context() is invoked and
-if ctx->nr_freq is non-zero, then the kernel will loop over ALL the
-events of the context looking for frequency mode ones. In doing, so it
-locks the context, and enable/disable the PMU of each hw event. If all
-the events of the context are in period mode, the kernel will have to
-traverse the list for nothing incurring overhead. The overhead is
-multiplied by a very large factor when this happens in a guest kernel.
-There is no need for the dummy event to be in frequency mode, it does
-not count anything and therefore should not cause extra overhead for
-no reason.
