There are places that check whether target task/cpu is given or not and some of them didn't check newly introduced uid or cpu list. Add and use three of helper functions to treat them properly. Signed-off-by:

The perf_target__strerror() sets @buf to a string that describes the (perf_target-specific) error condition that is passed via @errnum. This is similar to strerror_r() and does same thing if @errnum has a standard errno value. Signed-off-by:

Currently, 'perf record -- sleep 1' creates a cpu map for all online cpus since it turns out calling cpu_map__new(NULL). Fix it. Also it is guaranteed that cpu_list is NULL if PID/TID is given by calling perf_target__validate(), so we can make the conditional bit simpler. This also fixes perf test 7 (Validate) failure on my 6 core machine: $ cat /sys/devices/system/cpu/online 0-11 $ ./perf test -v 7 7: Validate PERF_RECORD_* events & perf_sample fields: --- start --- perf_evlist__mmap: Operation not permitted ---- end ---- Validate PERF_RECORD_* events & perf_sample fields: FAILED!

Check if neither of --pid, --tid or --uid was specified and if so, set system_wide appropriately. Namhyung's patch would make using any of the above target specifiers emit a warning in perf_target__validate, since it would see target.system_wide set and one of the others as well. So set system_wide after validation. Suggested-by:

Currently if we cannot decide the size of the event, we guess next event possition by: "... check alignment, and increment a single u64 in the hope to catch on again 'soon'" This usually ends up with segfault or endless loop. It's better to admit the failure right away, then pretend nothing happened. It makes the life easier ;) Signed-off-by:

As perf doesn't allow to specify gtk command-line option, drop the arguments and pass NULL to gtk_init(). This makes the function easier to be called from setup_browser(). Signed-off-by:

The setup_browser contained newt-related codes in it. As gtk front-end added recently, it should be more generic to handle both cases properly. So move newt codes to the ui__init() for now. Signed-off-by:

There were some combinations of these switches that are not so appropriate IMHO. Since there are implicit priorities between them and they worked well anyway, but it ends up opening useless duplicated events. For example, 'perf stat -t <pid> -a' will open multiple events for the thread instead of one. Add explicit checks and warn user in perf_target__validate(). Signed-off-by:

The perf_target__validate function is used to check given PID/TID/UID/CPU target options and warn if some combination is impossible. Also this can make some arguments of parse_target_uid() function useless as it is checked before the call via our new helper. Signed-off-by:

Use cpu-clock-tick sw counter for cpu-cycles only if there is no hw pmu available. This is the case if the syscall reports ENOENT. In other cases (e.g. invalid attributes) we don't want the sw counter to be used.

Currently the parsers objects (bison/flex related) are each time perf is built. No matter the generated files are already in place, the parser generation is executed every time. Changing the rules to have proper flex/bison objects generation dependencies. The parsers code is not rebuilt until the flex/bison source files are touched. Also when flex/bison source is changed, only dependent objects are rebuilt. Signed-off-by:

Now you can do $ make tools/<toolname> from the toplevel kernel directory and have the respective tool built. If you want to build and install it, do $ make tools/<toolname>_install $ make tools/<toolname>_clean should clean the respective tool directories. If you want to clean all in tools, simply do $ make tools/clean Also, if you want to get what the possible targets are, simply calling $ make tools/ should give you the short help. $ make tools/install installs all tools, of course.
