Move coloring logic into the hpp functions so that each value can be colored independently. It'd required for event group view. For overhead column, add a callback for printing 'folded_sign' of callchains of a hist entry. Signed-off-by:

The hpp helpers do same job for each field so it was implemented as macro in order to access those fields easily. But it gets cumbersome to maintain a large function in a macro as the function grows. Factor it out to a function with a little helper macro to access field. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.comSigned-off-by:

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.

Fixing the dynamic array format field parsing. Currently the event_read_fields function could segfault while parsing dynamic array other than string type. The reason is the event->pevent does not need to be set and gets dereferenced unconditionaly. Also adding proper initialization of field->elementsize based on the parsed dynamic type. Signed-off-by:
