* perf hists: Separate overhead and baseline columnsJiri Olsa2012-10-043-28/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the overhead and baseline columns are handled within single function and the distinction is made by 'baseline hists' pointer passed by 'struct perf_hpp::ptr'. Since hists pointer is now part of each hist_entry, it's possible to locate paired hists pointer directly from the passed struct hist_entry pointer. Also separating those 2 columns makes the code more obvious.

* perf diff: Refactor diff displacement possition infoJiri Olsa2012-10-047-40/+44
| | | | | | | | | | | | | | | | | | | | Moving the position calculation into the diff command, so the position as prepared inside struct hist_entry data and there's no need to compute in the output display path. Removing 'displacement' from struct perf_hpp as it is no longer needed.

* perf hists: Add struct hists pointer to struct hist_entryJiri Olsa2012-10-042-0/+3
| | | | | | | | | | | | | | | | | | | Adding pointer back to the parent struct hists for struct hists_entry. This will be useful in future for any hist_entry's data computation, that depends on total data of its parent hists.

* perf tools: Complete tracepoint event namesNamhyung Kim2012-10-041-2/+16
| | | | | | | | | | | | | | | | | | | | Currently tracepoint events cannot be completed because they contain a colon (:) character. The colon is considered as a word separator when bash completion is done - variable COMP_WORDBREAKS contains colon - so if a word being completed contains a colon it can be a problem. Recent versions of bash completion provide -n switch to _get_comp_words_by_ref and __ltrim_colon_completions functions in order to resolve this issue. Copy the latter in case not exists.

| | | | | | | | | | | | | | | | | | For building perf without stack backtrace debug, we can set NO_BACKTRACE=1 as a argument of make.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially should look loosely like the venerable 'strace' tool, but using the infrastructure in the perf tools to allow tracing extra targets: [acme@sandy linux]$ perf trace --hell Error: unknown option `hell' usage: perf trace <PID> -p, --pid <pid> trace events on existing process id --tid <tid> trace events on existing thread id --all-cpus system-wide collection from all CPUs --cpu <cpu> list of cpus to monitor --no-inherit child tasks do not inherit counters --mmap-pages <n> number of mmap data pages --uid <user> user to profile [acme@sandy linux]$ Those should have the same semantics as when using with 'perf record'. It gets stuck sometimes, but hey, it works sometimes too! In time it should support perf.data based workloads, i.e. it should have a: -o filename Command line option that will produce a perf.data file that can then be used with 'perf trace' or any of the other perf tools (script, report, etc). It will also eventually have the set of functionalities described in the previous 'trace' prototype by Thomas Gleixner: "Announcing a new utility: 'trace'" http://lwn.net/Articles/415728/ Also planned is to have some of the features suggested in the comments of that LWN article.

When that is in I'll just check that the perf_evsel__newtp constructor is not bailing out and then add it to the evlist, catch the event and check the filename against the one used in the 'open' call used to trigger the event.
