2009-08-31Merge branch 'perfcounters/tracing' into perfcounters/coreIngo Molnar
Merge reason: this topic is ready now to merge into the main development branch for .32, with functional perf trace output. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-08-18perf tools: Remove obsolete definesIngo Molnar
The _XOPEN_SOURCE* defines are not really needed on Linux and it's not like we'll port this to AIX ;-) The define also broke the build with gcc 4.4.1: CC util/trace-event-parse.o In file included from util/trace-event-parse.c:32: util/util.h:43:1: error: "_XOPEN_SOURCE" redefined So remove them.

2009-08-17perf tools: Add perf traceFrederic Weisbecker
This adds perf trace into the set of perf tools. It is written to fetch the tracepoint samples from perf events and display them, according to the events information given by the debugfs files through the util/trace* tools. It is a rough first shot and doesn't yet handle the cpu, timestamps fields and some other things. Example: perf record -f -e workqueue:workqueue_execution:record -F 1 -a perf trace kblockd/0-236 [000] 0.000000: workqueue_execution: thread=:236 func=cfq_kick_queue+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 Todo: - A lot of things!

2009-07-22perf_counter: Add tracepoint support to perf list, perf statJason Baron
Add support to 'perf list' and 'perf stat' for kernel tracepoints. The implementation creates a 'for_each_subsystem' and 'for_each_event' for easy iteration over the tracepoints.

2009-06-27perf_counter tools: Remove dead codeIngo Molnar
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.

The Git utils came with a ctype replacement that doesn't provide isprint(). Add a replacement. Solves a build bug on certain distros.

2009-06-06perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/Ingo Molnar
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.
