2016-01-12perf tools: Set and pass DOCDIR to builtin-report.cNamhyung Kim1-0/+1
It'll be used to locate perf document directory to find tips.txt in case it's not installed on the system.

Currently perf report only shows a help message "For a higher level overview, try: perf report --sort comm,dso" unconditionally (even if the sort keys were used).

2015-12-16perf tools: Provide subcmd configuration at runtimeJosh Poimboeuf1-1/+4
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.

2015-11-23perf tools: Add 'perf config' commandTaeung Song1-0/+1
The perf configuration file contains many variables to change various aspects of each of its tools, including output, disk usage, etc. But looking at the state of configuration is difficult and there's no documentation about config variables except for the variables in perfconfig.example exist. So this patch adds a 'perf-config' command with a '--list' option. perf config [options] display current perf config variables. # perf config -l | --list Signed-off-by: Taeung Song <treeze.taeung@gmail.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/1447768424-17327-1-git-send-email-treeze.taeung@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
