* perf tools: Remove hists from evselArnaldo Carvalho de Melo2014-10-141-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now tools that deals want to have an hists per evsel need to call hists__init() before creating any evsels, which can be as early as when parsing the command line, so do it before calling parse_options(). The current tools using hists/hist_entries are report, top and annotate, change them to request per evsel hists. This is in preparation for making evsels usable by 3rd party tools, that not necessarily live in perf's source code repository.

* perf session: Remove last reference to hists structArnaldo Carvalho de Melo2014-10-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now perf_session doesn't require that the evsels in its evlist are hists containing ones. Tools that are hists based and want to do per evsel events_stats updates, if at some point this turns into a necessity, should do it in the tool specific code, keeping the session class hists agnostic.

* perf tools: Check recorded kernel version when finding vmlinuxNamhyung Kim2014-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently vmlinux_path__init() only tries to find vmlinux file from current directory, /boot and some canonical directories with version number of the running kernel. This can be a problem when reporting old data recorded on a kernel version not running currently. We can use --symfs option for this but it's annoying for user to do it always. As we already have the info in the perf.data file, it can be changed to use it for the search automatically. Before: $ perf report ... # Samples: 4K of event 'cpu-clock' # Event count (approx.): 1067250000 # # Overhead Command Shared Object Symbol # ........ .......... ................. .............................. 71.87% swapper [kernel.kallsyms] [k] recover_probed_instruction After: # Overhead Command Shared Object Symbol # ........ .......... ................. .................... 71.87% swapper [kernel.kallsyms] [k] native_safe_halt This requires to change signature of symbol__init() to receive struct perf_session_env *.

* perf tools: Account entry stats when it's added to the output treeNamhyung Kim2014-04-241-2/+1
| | | | | | | | | | | | | | | | | | Currently, accounting each sample is done in multiple places - once when adding them to the input tree, other when adding them to the output tree. It's not only confusing but also can cause a subtle problem since concurrent processing like in perf top might see the updated stats before adding entries into the output tree - like seeing more (blank) lines at the end and/or slight inaccurate percentage. To fix this, only account the entries when it's moved into the output tree so that they cannot be seen prematurely. There're some exceptional cases here and there - they should be addressed separately with comments.

| | | | | | | | | | | | | | | | | | | | | | | Show multiple annotation result for each evsel. Each result represents the most frquently sampled symbol/function for the evsel and it will be shown in a tab window. For this add a reference to main container (notebook) to the pgctx. At the first call to annotate browser, hist_entry__find_annotations() will setup a new browser, and next calls will add new tabs to the browser.

Since most of these commands need it, we can add a global variable for it, also it can some other benefits: 1. When calling script browser inside hists/annotation browser, it needs to know the perf data file name to run that script. 2. For further feature like runtime switching to another perf data file, this variable can also help.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we were processing a PERF_RECORD_EXIT event we first used machine__findnew_thread for both the thread exiting and for its parent, only to use just the thread struct associated with the one exiting, and to just delete it. If it existed, i.e. not created at this very moment in machine__findnew_thread, it will be moved to the machine->dead_threads linked list, because we may have hist_entries pointing to it, but if it was created just do be deleted, it will just sit there with no references at all. Use the new machine__find_thread() method so that if it is not there, we don't create it. As a bonus the parent thread will also not be created at this point. Create process_fork() and process_exit() helpers to use this and make the builtins use it instead of the generic process_task(), ditched by this patch.

* perf tools: Use __maybe_used for unused variablesIrina Tirdea2012-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default input file for perf report is not handled the same way as perf record does it for its output file. This leads to unexpected behavior of perf report, etc. E.g.: # perf record -a -e cpu-cycles sleep 2 | perf report | cat failed to open perf.data: No such file or directory (try 'perf record' first) While perf record writes to a fifo, perf report expects perf.data to be read. This patch changes this to accept fifos as input file.
