* perf subcmd: Create subcmd libraryJosh Poimboeuf2015-12-171-100/+0
| | | | | | | | | | | | | | | Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.

* perf tools: Finalize subcmd independenceJosh Poimboeuf2015-12-171-1/+6
| | | | | | | | | | | | For the files that will be moved to the subcmd library, remove all their perf-specific includes and duplicate any needed functionality.

* perf tools: Provide subcmd configuration at runtimeJosh Poimboeuf2015-12-161-1/+7
| | | | | | | | | | | | | | Create init functions for exec_cmd.c and pager.c. This allows their configuration to be specified at runtime so they can be split out into a separate library which can be used by other programs. Their configuration is stored in a shared subcmd_config struct.

* perf tools: Remove check for unused PERF_PAGER_IN_USEJosh Poimboeuf2015-12-141-7/+1
| | | | | | | | | | | | | PERF_PAGER_IN_USE doesn't seem to be used anywhere, so let's remove it. This will also make it easier to move pager.c into a separate library.

* perf report: Fix some option handling on --stdioNamhyung Kim2015-05-141-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug that perf report sometimes ignore some options on --stdio output. This bug is triggered only if a related config variable is set. For example, let's assume we have a following config file. $ cat ~/.perfconfig [call-graph] print-type = graph [hist] percentage = absolute Then, following perf config will not honor some options. $ perf record -ag sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.199 MB perf.data (77 samples) ] $ perf report -g none --stdio # To display the perf.data header info, please use --header/--header-only options. # # Samples: 77 of event 'cycles' # Event count (approx.): 25425383 # # Overhead Command Shared Object Symbol # ........ ............... ....................... .............. # 16.34% swapper [kernel.vmlinux] [k] intel_idle | ---intel_idle cpuidle_enter_state cpuidle_enter cpu_startup_entry ... With '-g none' option, it should not show callchains, but it still shows callchains. However it works as expected on --tui output. Similarly, '--percentage relative' option is not work and still shows a absolute percentage values. Looking at the source, I found that those setting were overwritten by config variables when setup_pager() called. The setup_pager() is to start a pager process so that it can manage long lines of output on the stdio mode. But as it calls the perf_config() after parsing arguments, the settings were overwritten regardless of command line options. The reason it calls perf_config() is to find the 'pager_program' which might be set by a config variable, I guess. However current perf code does not provide the config variable for it, so it's just meaningless IMHO. Eliminating the call makes the option working as expected.

* perf tools: Add cat as fallback pagerMichael Lentine2014-05-211-6/+6
| | | | | | | | | | | This patch adds a fallback to cat for the pager. This is useful on environments, such as Android, where less does not exist. It is better to default to cat than to abort.

* perf_counter tools: Remove dead codeIngo Molnar2009-06-271-4/+1
| | | | | | | | | | | | | | | | Vince Weaver reported that there's a handful of #ifdef __MINGW32__ sections in the code. Remove them as they are in essence dead code - as unlike upstream Git, the perf tool is unlikely to be ported to Windows.

* perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/Ingo Molnar2009-06-061-0/+99
Several people have suggested that 'perf' has become a full-fledged tool that should be moved out of Documentation/. Move it to the (new) tools/ directory.
