The following changes since commit ce6c9da1113ad681bff27a3e376d2017f7f8a59c: Merge remote-tracking branch 'tip/perf/urgent' into perf/core (2018-10-18 11:13:01 -0300) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.20-20181025 for you to fetch changes up to fe57120e18a1f9124ca758c89cc54f91333d1847: perf script: Support total cycles count (2018-10-24 15:29:56 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: - Introduce 'perf trace --max-events' for stopping 'perf trace' when that many syscalls (enter+exit), tracepoints or other events such as page faults take place. Support that as well on a per-event basis, e.g.: perf trace -e sched:*switch/nr=2/,block:*_plug/nr=4/,block:*_unplug/nr=1/,net:*dev_queue/nr=3,max-stack=16/ Will stop when 2 context switches, 4 block plugs, 1 block unplug and 3 net_dev_queue tracepoints take place. (Arnaldo Carvalho de Melo) - Poll for monitored tasks being alive in 'perf stat -p/-t', exiting when those tasks all terminate (Jiri Olsa) - Encode -k clockid frequency into perf.data to enable timestamps derived metrics conversion into wall clock time on reporting stage. (Alexey Budankov) - Improve Intel PT call graph from SQL database and GUI python scripts, including adopting the Qt MDI interface to allow for multiple subwindows for all the tables, helping in better visualizing the data in the SQL tables, also uses, when available, the Intel XED disassembler libraries to present the Intel PT data as x86 asm mnemonics. This last feature is not currently working in some cases, fix is being discussed (Adrian Hunter) - Implement a ftrace function_graph view in 'perf script' when processing hardware trace data such as Intel PT (Andi Kleen) - Better integration with the Intel XED disassembler, when available, in 'perf script' (Andi Kleen) - Some 'perf trace' drop refcount fixes (Arnaldo Carvalho de Melo) - Add Sparc support to 'perf annotate', jitdump (David Miller) - Fix PLT symbols entry/header sizes properly on Sparc (David Miller) - Fix generation of system call table failure with /tmp mounted with 'noexec' in arm64 (Hongxu Jia) - Allow extended console debug output in 'perf script' (Milian Wolff) - Flush output stream after events in 'perf script' verbose mode (Milian Wolff) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Adrian Hunter (17): perf scripts python: call-graph-from-sql.py: Use SPDX license identifier perf scripts python: call-graph-from-sql.py: Provide better default column sizes perf scripts python: call-graph-from-sql.py: Set a minimum window size perf scripts python: call-graph-from-sql.py: Change icon perf scripts python: call-graph-from-sql.py: Make a "Main" function perf scripts python: call-graph-from-sql.py: Separate the database details into a class perf scripts python: call-graph-from-sql.py: Add a class for global data perf scripts python: call-graph-from-sql.py: Remove use of setObjectName() perf scripts python: call-graph-from-sql.py: Factor out CallGraphModel from TreeModel perf scripts python: call-graph-from-sql.py: Add data helper functions perf scripts python: call-graph-from-sql.py: Refactor TreeItem class perf scripts python: call-graph-from-sql.py: Rename to exported-sql-viewer.py perf scripts python: exported-sql-viewer.py: Add support for multiple sub-windows perf scripts python: exported-sql-viewer.py: Add ability to find symbols in the call-graph perf scripts python: exported-sql-viewer.py: Add ability to shrink / enlarge font perf scripts python: exported-sql-viewer.py: Add ability to display all the database tables perf scripts python: exported-sql-viewer.py: Add All branches report Alexey Budankov (1): perf record: Encode -k clockid frequency into Perf trace Andi Kleen (5): perf script: Add --insn-trace for instruction decoding perf script: Make itrace script default to all calls tools script: Add --call-trace and --call-ret-trace perf script: Implement --graph-function perf script: Support total cycles count Arnaldo Carvalho de Melo (7): tools lib subcmd: Introduce OPTION_ULONG perf trace: Introduce --max-events perf evsel: Introduce per event max_events property perf evsel: Mark a evsel as disabled when asking the kernel do disable it perf trace: Drop addr_location refcounts perf trace: Drop thread refcount in trace__event_handler() perf trace: Introduce per-event maximum number of events property David Miller (3): perf annotate: Add Sparc support perf jitdump: Add Sparc support. perf symbols: Set PLT entry/header sizes properly on Sparc Hongxu Jia (1): perf arm64: Fix generate system call table failed with /tmp mounted with noexec Jiri Olsa (1): perf stat: Poll for monitored tasks being alive Milian Wolff (2): perf script: Allow extended console debug output perf script: Flush output stream after events in verbose mode tools/lib/subcmd/parse-options.c | 19 + tools/lib/subcmd/parse-options.h | 2 + tools/perf/Documentation/build-xed.txt | 19 + tools/perf/Documentation/intel-pt.txt | 2 +- tools/perf/Documentation/itrace.txt | 7 +- tools/perf/Documentation/perf-script.txt | 18 + tools/perf/Documentation/perf-trace.txt | 67 + tools/perf/arch/arm64/entry/syscalls/mksyscalltbl | 2 +- tools/perf/arch/sparc/Makefile | 2 + tools/perf/arch/sparc/annotate/instructions.c | 169 ++ tools/perf/builtin-record.c | 24 +- tools/perf/builtin-script.c | 166 +- tools/perf/builtin-stat.c | 24 + tools/perf/builtin-trace.c | 50 +- tools/perf/perf.h | 1 + tools/perf/scripts/python/call-graph-from-sql.py | 339 ---- tools/perf/scripts/python/export-to-postgresql.py | 2 +- tools/perf/scripts/python/export-to-sqlite.py | 2 +- tools/perf/scripts/python/exported-sql-viewer.py | 2128 +++++++++++++++++++++ tools/perf/util/annotate.c | 8 + tools/perf/util/auxtrace.c | 17 +- tools/perf/util/auxtrace.h | 5 +- tools/perf/util/cs-etm.c | 3 +- tools/perf/util/env.h | 1 + tools/perf/util/evlist.c | 2 +- tools/perf/util/evsel.c | 27 +- tools/perf/util/evsel.h | 5 + tools/perf/util/genelf.h | 6 + tools/perf/util/header.c | 23 + tools/perf/util/header.h | 1 + tools/perf/util/intel-bts.c | 3 +- tools/perf/util/intel-pt.c | 3 +- tools/perf/util/parse-events.c | 8 + tools/perf/util/parse-events.h | 1 + tools/perf/util/parse-events.l | 1 + tools/perf/util/symbol-elf.c | 12 +- tools/perf/util/symbol.h | 3 +- tools/perf/util/thread.h | 2 + 38 files changed, 2778 insertions(+), 396 deletions(-) create mode 100644 tools/perf/Documentation/build-xed.txt create mode 100644 tools/perf/arch/sparc/annotate/instructions.c delete mode 100644 tools/perf/scripts/python/call-graph-from-sql.py create mode 100755 tools/perf/scripts/python/exported-sql-viewer.py Test results: The first ones are container (docker) based builds of tools/perf with and without libelf support. Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. 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 gcc (Alpine 5.3.0) 5.3.0 2 alpine:3.5 : Ok gcc (Alpine 6.2.1) 6.2.1 20160822 3 alpine:3.6 : Ok gcc (Alpine 6.3.0) 6.3.0 4 alpine:3.7 : Ok gcc (Alpine 6.4.0) 6.4.0 5 alpine:3.8 : Ok gcc (Alpine 6.4.0) 6.4.0 6 alpine:edge : Ok gcc (Alpine 6.4.0) 6.4.0 6 alpine:edge : Ok gcc (Alpine 6.4.0) 6.4.0 7 amazonlinux:1 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) 8 amazonlinux:2 : Ok gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5) 9 android-ndk:r12b-arm : Ok arm-linux-androideabi-gcc (GCC) 4.9.x 20150123 (prerelease) 10 android-ndk:r15c-arm : Ok arm-linux-androideabi-gcc (GCC) 4.9.x 20150123 (prerelease) 11 centos:5 : Ok gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-55) 12 centos:6 : Ok gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23) 13 centos:7 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) 14 debian:7 : Ok gcc (Debian 4.7.2-5) 4.7.2 15 debian:8 : Ok gcc (Debian 4.9.2-10+deb8u1) 4.9.2 16 debian:9 : Ok gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 17 debian:experimental : Ok gcc (Debian 8.2.0-7) 8.2.0 18 debian:experimental-x-arm64 : Ok aarch64-linux-gnu-gcc (Debian 8.2.0-7) 8.2.0 19 debian:experimental-x-mips : Ok mips-linux-gnu-gcc (Debian 8.2.0-7) 8.2.0 20 debian:experimental-x-mips64 : Ok mips64-linux-gnuabi64-gcc (Debian 8.1.0-12) 8.1.0 21 debian:experimental-x-mipsel : Ok mipsel-linux-gnu-gcc (Debian 8.2.0-7) 8.2.0 22 fedora:20 : Ok gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-7) 23 fedora:21 : Ok gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6) 24 fedora:22 : Ok gcc (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6) 25 fedora:23 : Ok gcc (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6) 26 fedora:24 : Ok gcc (GCC) 6.3.1 20161221 (Red Hat 6.3.1-1) 27 fedora:24-x-ARC-uClibc : Ok arc-linux-gcc (ARCompact ISA Linux uClibc toolchain 2017.09-rc2) 7.1.1 20170710 28 fedora:25 : Ok gcc (GCC) 6.4.1 20170727 (Red Hat 6.4.1-1) 29 fedora:26 : Ok gcc (GCC) 7.3.1 20180130 (Red Hat 7.3.1-2) 30 fedora:27 : Ok gcc (GCC) 7.3.1 20180712 (Red Hat 7.3.1-6) 31 fedora:28 : Ok gcc (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5) 32 fedora:rawhide : Ok gcc (GCC) 8.2.1 20180905 (Red Hat 8.2.1-3) 33 gentoo-stage3-amd64:latest : Ok gcc (Gentoo 7.3.0-r3 p1.4) 7.3.0 34 mageia:5 : Ok gcc (GCC) 4.9.2 35 mageia:6 : Ok gcc (Mageia 5.5.0-1.mga6) 5.5.0 36 opensuse:13.2 : Ok gcc (SUSE Linux) 4.8.3 20140627 [gcc-4_8-branch revision 212064] 37 opensuse:42.1 : Ok gcc (SUSE Linux) 4.8.5 38 opensuse:42.2 : Ok gcc (SUSE Linux) 4.8.5 39 opensuse:42.3 : Ok gcc (SUSE Linux) 4.8.5 40 opensuse:tumbleweed : Ok gcc (SUSE Linux) 7.3.1 20180323 [gcc-7-branch revision 258812] 41 oraclelinux:6 : Ok gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23.0.1) 42 oraclelinux:7 : Ok gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28.0.1) 43 ubuntu:12.04.5 : Ok gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 44 ubuntu:14.04.4 : Ok gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4 45 ubuntu:14.04.4-x-linaro-arm64 : Ok aarch64-linux-gnu-gcc (Linaro GCC 5.5-2017.10) 5.5.0 46 ubuntu:16.04 : Ok gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609 47 ubuntu:16.04-x-arm : Ok arm-linux-gnueabihf-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 48 ubuntu:16.04-x-arm64 : Ok aarch64-linux-gnu-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 49 ubuntu:16.04-x-powerpc : Ok powerpc-linux-gnu-gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 50 ubuntu:16.04-x-powerpc64 : Ok powerpc64-linux-gnu-gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 51 ubuntu:16.04-x-powerpc64el : Ok powerpc64le-linux-gnu-gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 52 ubuntu:16.04-x-s390 : Ok s390x-linux-gnu-gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 53 ubuntu:16.10 : Ok gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005 54 ubuntu:17.10 : Ok gcc (Ubuntu 7.2.0-8ubuntu3.2) 7.2.0 55 ubuntu:18.04 : Ok gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 56 ubuntu:18.04-x-arm : Ok arm-linux-gnueabihf-gcc (Ubuntu/Linaro 7.3.0-27ubuntu1~18.04) 7.3.0 57 ubuntu:18.04-x-arm64 : Ok aarch64-linux-gnu-gcc (Ubuntu/Linaro 7.3.0-27ubuntu1~18.04) 7.3.0 58 ubuntu:18.04-x-m68k : Ok m68k-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 59 ubuntu:18.04-x-powerpc : Ok powerpc-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 60 ubuntu:18.04-x-powerpc64 : Ok powerpc64-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 61 ubuntu:18.04-x-powerpc64el : Ok powerpc64le-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 62 ubuntu:18.04-x-riscv64 : Ok riscv64-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 63 ubuntu:18.04-x-s390 : Ok s390x-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 64 ubuntu:18.04-x-sh4 : Ok sh4-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 65 ubuntu:18.04-x-sparc64 : Ok sparc64-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0 66 ubuntu:18.10 : Ok gcc (Ubuntu 8.2.0-7ubuntu1) 8.2.0 #
