perf tools: Add new mem command for memory access profiling

2013-04-01T15:21:44Z

This new command is a wrapper on top of perf record and perf report to make it easier to configure for memory access profiling. To record loads: $ perf mem -t load rec ..... To record stores: $ perf mem -t store rec ..... To get the report: $ perf mem -t load rep Signed-off-by: Stephane Eranian Cc: Andi Kleen Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1359040242-8269-15-git-send-email-eranian@google.com [ Fixed minor conflict with 66857b5 "Sort command-list.txt alphabetically" ] Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Extract perf-specific stuff from debugfs.c

2013-03-15T16:06:01Z

Move them to util.c and simplify code a bit. Signed-off-by: Borislav Petkov Cc: Ingo Molnar Cc: Steven Rostedt Link: http://lkml.kernel.org/r/1361374353-30385-6-git-send-email-bp@alien8.de Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Introduce tools/lib/lk library

2013-03-15T16:06:00Z

This introduces the tools/lib/lk library, that will gradually have the routines that now are used in tools/perf/ and other tools and that can be shared. Start by carving out debugfs routines for general use.

perf tools: Remove some needless die() calls from the main routine

2013-01-24T19:40:52Z

Some would just call exit() anyway right after calling die() and the main routine doesn't have to call it, just return the exit value.

perf tools: Add gtk. config option for launching GTK browser

2012-11-14T19:51:30Z

Add config option for launching GTK browser for the specified command by default. Currently only 'report' command is supported. Adding following line to the perfconfig file will have a same effect of specifying --gtk option on command line (unless other related options are not given). $ cat ~/.perfconfig [gtk] report = true Signed-off-by: Namhyung Kim Acked-by: Pekka Enberg Cc: Ingo Molnar Cc: Paul Mackerras Cc: Pekka Enberg Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1352688617-25570-1-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tests: Add framework for automated perf_event_attr tests

2012-10-31T18:20:58Z

The idea is run perf session with kidnapping sys_perf_event_open function. For each sys_perf_event_open call we store the perf_event_attr data to the file to be checked later against what we expect. You can run this by: $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v v2 changes: - preserve errno value in the hook Signed-off-by: Jiri Olsa Cc: Arnaldo Carvalho de Melo Cc: Corey Ashford Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20121031145247.GB1027@krava.brq.redhat.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add a global variable "const char *input_name"

2012-10-29T13:45:34Z

Currently many perf commands annotate/evlist/report/script/lock etc all support "-i" option to chose a specific perf data, and all of them create a local "input_name" to save the file name for that perf data. 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.

perf tools: Have the page size value available for all tools

2012-10-06T19:33:14Z

Its such a common need that we might as well have a global with that value.

perf tools: Convert to LIBAUDIT_SUPPORT

2012-10-02T21:36:21Z

For building perf without libaudit, we can set NO_LIBAUDIT=1 as a argument of make. It then defines NO_LIBAUDIT_SUPPORT macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable.
