Some assert calls used in perf are also including some functionality (e.g. system calls), not only validity checks. Therefore, if NDEBUG is defined, this functionality will be removed along with the assert. Perf also defines BUG_ON based on assert, so it has the same problem. Define BUG_ON so that the condition will be executed when NDEBUG is defined. Replace the assert statements that have these side effects with BUG_ON. For defining BUG_ON, use "if (cond) {}" insted of "if (cond) ;" because in the latter case build fails with "error: suggest braces around empty body in an ‘if’ statement [-Werror=empty-body]" Suggested-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Reviewed-by: Namhyung Kim <namhyung@kernel.org> Reviewed-by: Pekka Enberg <penberg@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Namhyung Kim <namhyung.kim@lge.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/1347082551-2394-1-git-send-email-irina.tirdea@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> --- tools/perf/bench/sched-pipe.c | 6 +++--- tools/perf/util/include/linux/kernel.h | 4 ++++ 2 files changed, 7 insertions(+), 3 deletions(-) diff --git a/tools/perf/bench/sched-pipe.c b/tools/perf/bench/sched-pipe.c index 0c7454f..15911e9 100644 --- a/tools/perf/bench/sched-pipe.c +++ b/tools/perf/bench/sched-pipe.c @@ -56,13 +56,13 @@ int bench_sched_pipe(int argc, const char **argv, * causes error in building environment for perf */ int __used ret, wait_stat; - pid_t pid, retpid; + pid_t pid, retpid __used; argc = parse_options(argc, argv, options, bench_sched_pipe_usage, 0); - assert(!pipe(pipe_1)); - assert(!pipe(pipe_2)); + BUG_ON(pipe(pipe_1)); + BUG_ON(pipe(pipe_2)); pid = fork(); assert(pid >= 0); diff --git a/tools/perf/util/include/linux/kernel.h b/tools/perf/util/include/linux/kernel.h index b6842c1..4af9a10 100644 --- a/tools/perf/util/include/linux/kernel.h +++ b/tools/perf/util/include/linux/kernel.h @@ -47,8 +47,12 @@ #endif #ifndef BUG_ON +#ifdef NDEBUG +#define BUG_ON(cond) do { if (cond) {} } while (0) +#else #define BUG_ON(cond) assert(!(cond)) #endif +#endif /* * Both need more care to handle endianness -- 1.7.1 ^ permalink raw reply related [flat|nested] 42+ messages in thread

So when someone wants to add an option to manipulate the hist output it'd very easy to miss to update all of them in sync. And things getting worse as more options/features are added continuously. So I'd like to refactor them using hpp formats and move common code to ui/hist.c in order to make it easy to maintain and to add new features.

The following changes since commit 3906a13a6b4e78fbc0def03a808f091f0dff1b44: Merge tag 'perf-core-for-mingo-4.12-20170327' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2017-03-28 07:44:43 +0200) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.12-20170331 for you to fetch changes up to fd5cead23f54697310bd565aa2a23ae5128080a0: perf trace: Beautify statx syscall 'flag' and 'mask' arguments (2017-03-31 14:42:31 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: New features: - Beautify the statx syscall arguments in 'perf trace' (Arnaldo Carvalho de Melo) e.g.: System wide strace like session: # trace -e statx 16612.967 ( 0.028 ms): statx/4562 statx(dfd: CWD, filename: /tmp/statx, flags: SYMLINK_NOFOLLOW, mask: TYPE|MODE|NLINK|UID|GID|ATIME|MTIME|CTIME|INO|SIZE|BLOCKS|BTIME, buffer: 0x7ffef195d660) = 0 36050.891 ( 0.007 ms): statx/4576 statx(dfd: CWD, filename: /etc/passwd, flags: SYMLINK_NOFOLLOW|STATX_DONT_SYNC, mask: BTIME, buffer: 0x7ffda9bf50f0) = 0 ^C# User visible: - Handle unpaired raw_syscalls:sys_exit events in 'perf trace', i.e. we shouldn't try to calculate duration or print the timestamp for a missing matching raw_syscalls:sys_enter (Arnaldo Carvalho de Melo) - Do not print "cycles: 0" in perf report LBR lines in platforms not supporting 'cycles', such as Intel's Broadwell (Jin Yao) - Handle missing $HOME env var (Jiri Olsa) - Map 8-bit registers (al, bl, etc), not supported in uprobes_events, to the next best thing (ax, bx, etc) supported (Ravi Bangoria) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> ---------------------------------------------------------------- Arnaldo Carvalho de Melo (4): perf tools: Remove support for command aliases perf trace: Handle unpaired raw_syscalls:sys_exit event tools include uapi: Grab copies of stat.h and fcntl.h perf trace: Beautify statx syscall 'flag' and 'mask' arguments Colin Ian King (1): perf utils: Fix spelling mistake: "Invalud" -> "Invalid" Jin Yao (1): perf report: Drop cycles 0 for LBR print Jiri Olsa (1): perf tools: Do not fail in case of empty HOME env variable Ravi Bangoria (2): perf/sdt/x86: Add renaming logic for (missing) 8 bit registers perf/sdt/x86: Move OP parser to tools/perf/arch/x86/ tools/include/linux/types.h | 1 + tools/include/uapi/linux/fcntl.h | 72 +++++++++ tools/include/uapi/linux/stat.h | 176 ++++++++++++++++++++ tools/perf/Build | 1 + tools/perf/MANIFEST | 2 + tools/perf/arch/x86/entry/syscalls/syscall_64.tbl | 1 + tools/perf/arch/x86/util/perf_regs.c | 187 ++++++++++++++++++---- tools/perf/builtin-help.c | 13 -- tools/perf/builtin-trace.c | 57 ++++--- tools/perf/check-headers.sh | 2 + tools/perf/perf.c | 97 +---------- tools/perf/trace/beauty/Build | 1 + tools/perf/trace/beauty/beauty.h | 24 +++ tools/perf/trace/beauty/statx.c | 72 +++++++++ tools/perf/util/Build | 1 - tools/perf/util/alias.c | 78 --------- tools/perf/util/cache.h | 1 - tools/perf/util/callchain.c | 111 ++++++++----- tools/perf/util/config.c | 54 ++++--- tools/perf/util/help-unknown-cmd.c | 8 +- tools/perf/util/hist.c | 2 +- tools/perf/util/perf_regs.c | 6 +- tools/perf/util/perf_regs.h | 11 +- tools/perf/util/probe-file.c | 132 +++++---------- 24 files changed, 707 insertions(+), 403 deletions(-) create mode 100644 tools/include/uapi/linux/fcntl.h create mode 100644 tools/include/uapi/linux/stat.h create mode 100644 tools/perf/trace/beauty/Build create mode 100644 tools/perf/trace/beauty/beauty.h create mode 100644 tools/perf/trace/beauty/statx.c delete mode 100644 tools/perf/util/alias.c Test results: The first ones are container (docker) based builds of tools/perf with and without libelf support, objtool where it is supported and samples/bpf/, ditto. Where clang is available, it is also used to build perf with/without libelf. For this specific pull request the samples/bpf/ was disabled, as 'make headers_install' is failing with the following error, in this case in fedora:rawhide: INSTALL usr/include/uapi/ (0 file) /git/linux/scripts/Makefile.headersinst:62: *** Missing generated UAPI file ./arch/x86/include/generated/uapi/asm/unistd_32.h.

Several are cross builds, the ones with -x-ARCH, and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. # dm 1 alpine:3.4: Ok 2 alpine:3.5: Ok 3 alpine:edge: Ok 4 android-ndk:r12b-arm: Ok 5 archlinux:latest: Ok 6 centos:5: Ok 7 centos:6: Ok 8 centos:7: Ok 9 debian:7: Ok 10 debian:8: Ok 11 debian:9: Ok 12 debian:experimental: Ok 13 debian:experimental-x-arm64: Ok 14 debian:experimental-x-mips: Ok 15 debian:experimental-x-mips64: Ok 16 debian:experimental-x-mipsel: Ok 17 fedora:20: Ok 18 fedora:21: Ok 19 fedora:22: Ok 20 fedora:23: Ok 21 fedora:24: Ok 22 fedora:24-x-ARC-uClibc: Ok 23 fedora:25: Ok 24 fedora:rawhide: Ok 25 mageia:5: Ok 26 opensuse:13.2: Ok 27 opensuse:42.1: Ok 28 opensuse:tumbleweed: Ok 29 ubuntu:12.04.5: Ok 30 ubuntu:14.04.4: Ok 31 ubuntu:14.04.4-x-linaro-arm64: Ok 32 ubuntu:15.10: Ok 33 ubuntu:16.04: Ok 34 ubuntu:16.04-x-arm: Ok 35 ubuntu:16.04-x-arm64: Ok 36 ubuntu:16.04-x-powerpc: Ok 37 ubuntu:16.04-x-powerpc64: Ok 38 ubuntu:16.04-x-s390: Ok 39 ubuntu:16.10: Ok 40 ubuntu:17.04: Ok # # uname -a Linux jouet 4.11.0-rc2+ #5 SMP Mon Mar 20 18:12:29 -03 2017 x86_64 x86_64 x86_64 GNU/Linux # 'perf test tsc' already fixed by peterz in tip # perf test 1: vmlinux symtab matches kallsyms : Ok 2: Detect openat syscall event : Ok 3: Detect openat syscall event on all cpus : Ok 4: Read samples using the mmap interface : Ok 5: Parse event definition strings : Ok 6: Simple expression parser : Ok 7: PERF_RECORD_* events & perf_sample fields : Ok 8: Parse perf pmu format : Ok 9: DSO data read : Ok 10: DSO data cache : Ok 11: DSO data reopen : Ok 12: Roundtrip evsel->name : Ok 13: Parse sched tracepoints fields : Ok 14: syscalls:sys_enter_openat event fields : Ok 15: Setup struct perf_event_attr : Ok 16: Match and link multiple hists : Ok 17: 'import perf' in python : Ok 18: Breakpoint overflow signal handler : Ok 19: Breakpoint overflow sampling : Ok 20: Number of exit events of a simple workload : Ok 21: Software clock events period values : Ok 22: Object code reading : Ok 23: Sample parsing : Ok 24: Use a dummy software event to keep tracking: Ok 25: Parse with no sample_id_all bit set : Ok 26: Filter hist entries : Ok 27: Lookup mmap thread : Ok 28: Share thread mg : Ok 29: Sort output of hist entries : Ok 30: Cumulate child hist entries : Ok 31: Track with sched_switch : Ok 32: Filter fds with revents mask in a fdarray : Ok 33: Add fd to a fdarray, making it autogrow : Ok 34: kmod_path__parse : Ok 35: Thread map : Ok 36: LLVM search and compile : 36.1: Basic BPF llvm compile : Ok 36.2: kbuild searching : Ok 36.3: Compile source for BPF prologue generation: Ok 36.4: Compile source for BPF relocation : Ok 37: Session topology : Ok 38: BPF filter : 38.1: Basic BPF filtering : Ok 38.2: BPF pinning : Ok 38.3: BPF prologue generation : Ok 38.4: BPF relocation checker : Ok 39: Synthesize thread map : Ok 40: Remove thread map : Ok 41: Synthesize cpu map : Ok 42: Synthesize stat config : Ok 43: Synthesize stat : Ok 44: Synthesize stat round : Ok 45: Synthesize attr update : Ok 46: Event times : Ok 47: Read backward ring buffer : Ok 48: Print cpu map : Ok 49: Probe SDT events : Ok 50: is_printable_array : Ok 51: Print bitmap : Ok 52: perf hooks : Ok 53: builtin clang support : Skip (not compiled in) 54: unit_number__scnprintf : Ok 55: x86 rdpmc : Ok 56: Convert perf time to TSC : FAILED!

After building perf tools, I deleted builtin-{sched,test,script}.o to rebuild the only since they are largest ones. namhyung@leonhard:perf$ ls -lS *.c | head -3 -rw-r--r-- 1 namhyung namhyung 45522 2012-10-27 00:20 builtin-sched.c -rw-r--r-- 1 namhyung namhyung 36372 2012-10-27 00:20 builtin-test.c -rw-r--r-- 1 namhyung namhyung 35555 2012-10-27 00:20 builtin-script.c namhyung@leonhard:perf$ rm builtin-{sched,test,script}.o And then building each file with time command shows this: namhyung@leonhard:perf$ time make builtin-script.o &> /dev/null real 0m4.577s user 0m2.755s sys 0m1.655s namhyung@leonhard:perf$ time make builtin-test.o &> /dev/null real 0m4.486s user 0m2.707s sys 0m1.658s namhyung@leonhard:perf$ time make builtin-sched.o &> /dev/null real 0m16.936s user 0m15.157s sys 0m1.635s You can see it easily when building perf without -j option.

The optimal way, I guess, would be to have some cache file with the results of such feature tests, that would be created and then used till the build fails using its findings, which would trigger a new feature check round, followed by an automatic rebuild. That would be tricky because we would have to have an automated way of discovering if the build failed due to missing packages or if it failed due to some ordinary coding mistake. - Arnaldo ^ permalink raw reply [flat|nested] 42+ messages in thread

The feature tests aren't a big problem right now - but making it *visible* is really useful.

Right now the CHK tests are serialized and they take several seconds to build and run. A parallel make rule would reduce that to about a second I think.

I did not write that. I think making the feature tests parallel would be enough to speed it all up - caching brings in a new set of problems.

Just wondering what detail causes that failure - the whole point of --uid mingo would be to enable nonprivileged users to do 'session wide' profiling, *especially* if paranoia is high. So what does --uid do which perf record --pid 1234 wouldnt already do? By all means --uid ought to be a fancy way of doing a whole bunch of perf record --pid 1234 profiling sessions, at once.
