  perf report: Sort by sampled cycles percent per block for tui (2019-11-07 10:14:48 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report:

  Jin Yao:

  - Introduce --total-cycles, for basic block profiling, further using data
    obtained from LBR, an example should suffice:

      # perf record -b
      ^C[ perf record: Woken up 595 times to write data ]
      [ perf record: Captured and wrote 156.672 MB perf.data (196873 samples) ]

      # perf evlist -v
      cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|BRANCH_STACK, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, precise_ip: 3, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1, branch_sample_type: ANY

      # perf report --total-cycles --stdio
      # To display the perf.data header info, please use --header/--header-only options.
      #
      # Total Lost Samples: 0
      #

perf record:

  Adrian Hunter:

  - Allow storing perf.data in a directory together with a copy of /proc/kcore.

  Jiwei Sun:

  - Add support for limit perf output file size, i.e.:

    # perf record --all-cpus -F 10000 --max-size=4M sleep 10h
    [ perf record: perf size limit reached (4097 KB), stopping session ]
    [ perf record: Woken up 6 times to write data ]
    [ perf record: Captured and wrote 4.048 MB perf.data (54094 samples) ]
    Terminated
    # ls -lah perf.data
    -rw-------. 1 root root 4.1M Nov  7 15:27 perf.data
    #

perf stat:

  Jiri Olsa:

  - Add --per-node agregation support:

    In live mode:

      # perf stat  -a -I 1000 -e cycles --per-node
      #           time node   cpus             counts unit events
           1.000542550 N0       20          6,202,097      cycles
           1.000542550 N1       20            639,559      cycles
           2.002040063 N0       20          7,412,495      cycles
           2.002040063 N1       20          2,185,577      cycles
           3.003451699 N0       20          6,508,917      cycles
           3.003451699 N1       20            765,607      cycles
      ...

    Or in the record/report stat session:

      # perf stat record -a -I 1000 -e cycles
      #           time             counts unit events
           1.000536937         10,008,468      cycles
           2.002090152          9,578,539      cycles
           3.003625233          7,647,869      cycles
           4.005135036          7,032,086      cycles
      ^C     4.340902364          3,923,893      cycles

      # perf stat report --per-node
      #           time node   cpus             counts unit events
           1.000536937 N0       20          9,355,086      cycles

           2.002090152 N1       20          1,865,701      cycles
       ...

perf probe:

  Masami Hiramatsu:

  Various fixes related to recent additions to the DWARF format:

  - Fix to find range-only function instance

  - Walk function lines in lexical blocks

  - Fix to show function entry line as probe-able

  - Fix wrong address verification

  - Fix to probe a function which has no entry pc

  - Fix to probe an inline function which has no entry pc

  - Fix to list probe event with correct line number

  - Fix to show inlined function callsite without entry_pc

  - Fix to show ranges of variables in functions without entry_pc

  - Return a better scope DIE if there is no best scope

  - Skip end-of-sequence and non statement lines

  - Filter out instances except for inlined subroutine and subprogram

  - Fix to show calling lines of inlined functions

  - Skip overlapped location on searching variables

perf inject:

  - Do not strip evsels with --strip, as they are needed for create_gcov
    (see the autofdo example in tools/perf/Documentation/intel-pt.txt).

Intel PT:

  Adrian Hunter:

  - Intel PT uses an auxtrace_cache to store the results of code-walking, to avoid
    repeated decoding. Add an auxtrace_cache__remove to handle text poke events.

core:

  Andi Kleen:

  - Always preserve errno while cleaning up perf_event_open failures.

llvm:

  Arnaldo Carvalho de Melo:

  - No need to tell that the request for saving a .o file for BPF events, as
    expressed in ~/.perfconfig was satisfied, make that a debug message.

perf vendor events:

Intel:

  Haiyan Song:

  - Update CascadelakeX events to v1.05.

  - Update all the Intel JSON metrics from TMAM 3.6.

Treewide:

  Ian Rogers:

  - Improve error paths, plugging leaks found using LLVM tools
    such as libFuzzer.

jevents:

  Yunfeng Ye:

  - Fix resource leak in process_mapfile() and main()

perf kvm:

  Igor Lubashev:

  - Use evlist layer api when possible.

libsubcmd:

  James Clark:

  - Move EXTRA_FLAGS to the end to allow overriding existing flags.

  - Use -O0 with DEBUG=1

perf diff:

  Jin Yao:

  - Don't use hack to skip column length calculation

CoreSight ETM:

  Leo yan:

  - Fix definition of macro TO_CS_QUEUE_NR

ARM64:

  John Garry:

  - Do not try to include libelf header files when its feature detection
    failed, fixing the cross build for ARM64.

perf tests:

  Leo Yan:

  - Fix out of bounds memory access in the backward ring buffer test.

Test results:

The first ones are container 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.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.
