2013-01-31perf ui/hist: Consolidate hpp helpersNamhyung Kim
Most of hpp helper functions do same jobs for different fields thus consolidate them to appropriate functions/macros.

2013-01-31perf hists: Resort hist entries using group members for outputNamhyung Kim
When event group is enabled, sorting hist entries on periods for output should consider groups members' period also. To do that, build period table using link/pair information and compare the table.

2013-01-31perf report: Make another loop for linking group histsNamhyung Kim
Now the event grouping viewing requires linking all member hists in a group to the leader's. Thus hists__output_resort should be called after linking all events in evlist. Introduce symbol_conf.event_group flag to determine whether the feature is enabled or not.

2013-01-30perf tools, powerpc: Fix compile warnings in tests/attr.cSukadev Bhattiprolu
We print several '__u64' quantities using '%llu'. On powerpc, we by default include '<asm-generic/int-l64.h> which results in __u64 being an unsigned long. This causes compile warnings which are treated as errors due to '-Werror'. By defining __SANE_USERSPACE_TYPES__ we include <asm-generic/int-ll64.h> and define __u64 as unsigned long long. Changelog[v2]: [Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64 format specifier - which as Jiri Olsa pointed out, breaks on x86-64.

2013-01-30perf stat: Add interval printingStephane Eranian
This patch adds a new printing mode for perf stat. It allows interval printing. That means perf stat can now print event deltas at regular time interval. This is useful to detect phases in programs. The -I option enables interval printing. It expects an interval duration in milliseconds. Minimum is 100ms. Once, activated perf stat prints events deltas since last printout. All modes are supported. $ perf stat -I 1000 -e cycles noploop 10 noploop for 10 seconds # time counts events 1.000109853 2,388,560,546 cycles 2.000262846 2,393,332,358 cycles 3.000354131 2,393,176,537 cycles 4.000439503 2,393,203,790 cycles 5.000527075 2,393,167,675 cycles 6.000609052 2,393,203,670 cycles 7.000691082 2,393,175,678 cycles The output format makes it easy to feed into a plotting program such as gnuplot when the -I option is used in combination with the -x option: $ perf stat -x, -I 1000 -e cycles noploop 10 noploop for 10 seconds 1.000084113,2378775498,cycles 2.000245798,2391056897,cycles 3.000354445,2392089414,cycles 4.000459115,2390936603,cycles 5.000565341,2392108173,cycles Signed-off-by: Stephane Eranian <eranian@google.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung.kim@lge.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1359460064-3060-3-git-send-email-eranian@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2013-01-30perf: Add 'perf bench numa mem' NUMA performance measurement suiteIngo Molnar
Add a suite of NUMA performance benchmarks. The goal was simulate the behavior and access patterns of real NUMA workloads, via a wide range of parameters, so this tool goes well beyond simple bzero() measurements that most NUMA micro-benchmarks use: - It processes the data and creates a chain of data dependencies, like a real workload would. Neither the compiler, nor the kernel (via KSM and other optimizations) nor the CPU can eliminate parts of the workload. - It randomizes the initial state and also randomizes the target addresses of the processing - it's not a simple forward scan of addresses. - It provides flexible options to set process, thread and memory relationship information: -G sets "global" memory shared between all test processes, -P sets "process" memory shared by all threads of a process and -T sets "thread" private memory. - There's a NUMA convergence monitoring and convergence latency measurement option via -c and -m. - Micro-sleeps and synchronization can be injected to provoke lock contention and scheduling, via the -u and -S options. This simulates IO and contention. - The -x option instructs the workload to 'perturb' itself artificially every N seconds, by moving to the first and last CPU of the system periodically. This way the stability of convergence equilibrium and the number of steps taken for the scheduler to reach equilibrium again can be measured. - The amount of work can be specified via the -l loop count, and/or via a -s seconds-timeout value. - CPU and node memory binding options, to test hard binding scenarios. THP can be turned on and off via madvise() calls. - Live reporting of convergence progress in an 'at glance' output format. Printing of convergence and deconvergence events. The 'perf bench numa mem -a' option will start an array of about 30 individual tests that will each output such measurements: # Running 5x5-bw-thread, "perf bench numa mem -p 5 -t 5 -P 512 -s 20 -zZ0q --thp 1" 5x5-bw-thread, 20.276, secs, runtime-max/thread 5x5-bw-thread, 20.004, secs, runtime-min/thread 5x5-bw-thread, 20.155, secs, runtime-avg/thread 5x5-bw-thread, 0.671, %, spread-runtime/thread 5x5-bw-thread, 21.153, GB, data/thread 5x5-bw-thread, 528.818, GB, data-total 5x5-bw-thread, 0.959, nsecs, runtime/byte/thread 5x5-bw-thread, 1.043, GB/sec, thread-speed 5x5-bw-thread, 26.081, GB/sec, total-speed See the help text and the code for more details.

2013-01-24perf script: hook up perf_scripting_context->peventTom Zanussi
Running the check-perf-trace scripts causes segfaults in both the Perl and Python cases: # perf script record check-perf-trace # perf script -s libexec/perf-core/scripts/python/check-perf-trace.py trace_begin Segmentation fault (core dumped) The reason is that the 'pevent' field was added to perf_scripting_context but it wasn't hooked up with an actual pevent in either case, so when one of the 'common' fields is accessed (in util/trace-event-parse.c:get_common_fields()), pevent->events tries to dereference a NULL pointer. This sets the pevent field when the scripting context is set up.

Only display the trace info if using the default event display. When invoking scripts we assume they have complete control of what's displayed so we shouldn't unconditionally display the trace info, and when generating scripts we don't expect to see trace info obscuring the output message.

On POWER, the 'perf format parsing' test always fails. Looks like it is because memset() is being passed number of longs rather than number of bytes. It is interesting that the test always passes on my x86 box. With this patch, the test passes on POWER and continues to pass on x86.

2013-01-24perf tools: Do not include PERF-VERSION-FILE to MakefileNamhyung Kim
When make runs it tries to update the Makefile rules by reading all of included Makefiles. During the perf build it checks PERF-VERSION-FILE to get the current version number. But it triggers Makefile update so that make runs again with the update Makefile and, in turn, users will see duplicate CHK message on the second path. Running make with -d option for debugging tells me this: GNU Make 3.82 Built for x86_64-redhat-linux-gnu Copyright (C) 2010 Free Software Foundation, Inc.
