perf evswitch: Introduce init() method to set the on/off evsels from the command line

2019-08-15T15:25:55Z

Another step in having all the boilerplate in just one place to then use in the other tools. Cc: Adrian Hunter Cc: Florian Weimer Cc: Jiri Olsa Cc: Namhyung Kim Cc: William Cohen Link: https://lkml.kernel.org/n/tip-snreb1wmwyjei3eefwotxp1l@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf evswitch: Introduce OPTS_EVSWITCH() for cmd line processing

2019-08-15T15:25:47Z

All tools will want those, so provide a convenient way to get them. Cc: Adrian Hunter Cc: Florian Weimer Cc: Jiri Olsa Cc: Namhyung Kim Cc: William Cohen Link: https://lkml.kernel.org/n/tip-v16pe3sbf3wjmn152u18f649@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf evswitch: Add the names of on/off events

2019-08-15T15:24:42Z

So that we can have macros for the OPT_ entries and also for finding those in an evlist, this way other tools will use this very easily.

perf evswitch: Move switch logic to use in other tools

2019-08-15T15:24:31Z

Now other tools that want switching can use an evswitch for that, just set it up and add it to the PERF_RECORD_SAMPLE processing function.

perf evswitch: Move struct to a separate header to use in other tools

2019-08-15T15:24:24Z

Now that we see that the simple userspace-based "slicing" of events using delimiter events ("markers") works, lets move it to a separate header to make it available to other tools, next step will be having the switch on/off check done at the PERF_RECORD_SAMPLE processing function moved too.
