perf annotate browser: Help for cycling thru hottest instructions with TAB/shift+TAB (2017-09-01 14:55:40 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Support syscall name glob matching in 'perf trace' (Arnaldo Carvalho de Melo)
e.g.:
# perf trace -e pkey_*
32.784 (0.006 ms): pkey/16018 pkey_alloc(init_val: DISABLE_WRITE) = -1 EINVAL Invalid argument
32.795 (0.004 ms): pkey/16018 pkey_mprotect(start: 0x7f380d0a6000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
32.801 (0.002 ms): pkey/16018 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
^C#
- Do not auto merge counts for explicitely specified events in
'perf stat' (Arnaldo Carvalho de Melo)
- Fix syntax in documentation of .perfconfig intel-pt option (Jack Henschel)
- Calculate the average cycles of iterations for loops detected by the
branch history support in 'perf report' (Jin Yao)
- Support PERF_SAMPLE_PHYS_ADDR as a sort key "phys_daddr" in the 'script', 'mem',
'top' and 'report'. Also add a test entry for it in 'perf test' (Kan Liang)
- Fix 'Object code reading' 'perf test' entry in PowerPC (Ravi Bangoria)
- Remove some duplicate Power9 duplicate vendor events (described in JSON
files) (Sukadev Bhattiprolu)
- Add help entry in the TUI annotate browser about cycling thru hottest
instructions with TAB/shift+TAB (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>

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.
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.
The 'perf test' also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.
Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.
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.
