| | | | | | | | | More needs to be done to have the actual functions and variables in a smaller .c file that can then be included in the python binding, avoiding dragging more stuff into it.

* perf tools: Include sys/param.h where neededArnaldo Carvalho de Melo2017-04-241-0/+1
| | | | | | | | | | As it is going away from util.h, where it is not needed. This is mostly for things like MAXPATHLEN, MAX() and MIN(), these later two probably should go away in favor of its kernel sources replacements.

* perf c2c: Fix display bug when using pipeNamhyung Kim2017-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently 'perf c2c report' determines display mode using the --stdio option, but it could be a problem if stdout is not a tty since setup_browser falls back to stdio in this case. But perf c2c didn't know this and tried to use TUI browser anyway. It should check "use_browser" variable instead. For example, the following command showed nothing and broke terminal setting. Now it's fixed.. $ perf c2c report | head ================================================= Trace Event Information ================================================= Total records : 136 Locked Load/Store Operations : 6 Load Operations : 62 Loads - uncacheable : 0 Loads - IO : 1 Loads - Miss : 7 Loads - no mapping : 2 Committer notes: When trying it without a proper perf.data file it results in a stuck terminal, just as Namhyung reported above: [acme@jouet ~]$ perf c2c report | head WARNING: no sample cpu value[acme@jouet ~]$ One has to kill it from some other xterm.

The problem is that they might not be always counted and 'perf c2c report' displays an empty output.
