2013-02-14perf tools: Fix build with bison 2.3 and older.Vinson Lee
The %name-prefix "prefix" syntax is not available on bison 2.3 and older. Substitute with the -p "prefix" command-line option for compatibility with older versions of bison.

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 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.

2013-01-24perf tests: Check python path on attr and binding testNamhyung Kim
Current perf test code tries to execute python version 2 in order to test attributes on perf_event_open syscall. However it's not default python version anymore a system can have python v3 only or v2 with a different name (e.g. python2). So if there's no such python interpreter with the name 'python', the test would fail like this (yes, it's happened on my new archlinux laptop :). 13: struct perf_event_attr setup :sh: python: command not found FAILED!

2013-01-24perf test: Add a test case for hists__{match,link}Namhyung Kim
As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.

2012-11-19perf: Make perf build for x86 with UAPI disintegration appliedDavid Howells
Make perf build for x86 once the UAPI disintegration patches for that arch have been applied by adding the appropriate -I flags - in the right order - and then converting some #includes that use ../.. notation to find main kernel headerfiles to use <asm/foo.h> and <linux/foo.h> instead. Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include. This makes sure we get the userspace version of the pt_regs struct. Ideally, we wouldn't have the latter -I flag at all, but unfortunately we want asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI - at least not for x86. I wonder if the bits outside of the __KERNEL__ guards *should* be transferred there. I note also that perf seems to do its dependency handling manually by listing all the header files it might want to use in LIB_H in the Makefile. Can this be changed to use -MD? Note that to do make this work, we need to export and UAPI disintegrate linux/hw_breakpoint.h, which I think should've been exported previously so that perf can access the bits. We have to do this in the same patch to maintain bisectability. Signed-off-by: David Howells <dhowells@redhat.com>

2012-10-29perf scripts browser: Add a browser for perf scriptFeng Tang
Create a script browser, so that user can check all the available scripts for current perf data file and run them inside the main perf report or annotation browsers, for all perf samples or for samples belong to one thread/symbol. Please be noted: current script browser is only for report use, and doesn't cover the record phase, IOW it must run against one existing perf data file. The work flow is, users can use function key to list all the available scripts for current perf data file in system and chose one, which will be executed with popen("perf script -s xxx.xx",) and all the output lines are put into one ui browser, pressing 'q' or left arrow key will make it return to previous browser.
