      perf tools: Add automated make test suite · 095ae69b
      由 Jiri Olsa 提交于 
      Adding automated test for testing the build process.

To run it you need to be in perf directory or specify one with PERF
variable. It's also possible to specify optional Makefile to test via MK
variable.

Whole suite is executed twice, the second time with O=/tmp/xxx option
added.

To run the whole suite:
  $ make -f tests/make
  - make_pure: cd . && make -f Makefile
    test: test -x ./perf
  - make_clean_all: cd . && make -f Makefile clean all
    test: test -x ./perf
  - make_python_perf_so: cd . && make -f Makefile python/perf.so
    test: test -f ./python/perf.so
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf
  - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1
    test: test -x ./perf

You see command line for 'make_pure' test right away, and the output is
stored into 'make_pure' file.

To run simple test:
  $ make -f tests/make make_debug
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf

At this moment tests checks for successfull build and for existence of
several built files. Additional after-build checks could be added.

      perf tests: Fix compile errors in bp_signal files · b3539d21
      由 Sukadev Bhattiprolu 提交于 
      When building on powerpc,  we get compile errors in bp_signal.c and
bp_signal_overflow.c due to __u64 and '%llx'.

Powerpc, needs __SANE_USERSPACE_TYPES__ to be defined so we pick up
<asm-generic/int-ll64.h> and define __u64 as unsigned long long.

      perf tools: Add support for weight v7 (modified) · 05484298
      由 Andi Kleen 提交于 
      perf record has a new option -W that enables weightened sampling.

Add sorting support in top/report for the average weight per sample and the
total weight sum. This allows to both compare relative cost per event
and the total cost over the measurement period.

Add the necessary glue to perf report, record and the library.

v2: Merge with new hist refactoring.
v3: Fix manpage. Remove value check.
Rename global_weight to weight and weight to local_weight.
v4: Readd sort keys to manpage
v5: Move weight to end
v6: Move weight to template
v7: Rename weight key.

Original patch from Andi modified by Stephane Eranian <eranian@google.com>
to include ONLY the weight supporting code and apply to pristine 3.8.0-rc4.

      perf test: Allow skipping tests · 2ae82878
      由 Arnaldo Carvalho de Melo 提交于 
      Sometimes a test is problematic for some reason and one wants to skip it,
for instance:

[root@sandy ~]# perf test
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     :  Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: function is_writable_pte not defined
  Segmentation fault (core dumped)

So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:

  [root@sandy ~]# perf test -s 5
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     : Skip (user override)
   6: x86 rdpmc test                                         : Ok
   7: Validate PERF_RECORD_* events & perf_sample fields     : Ok
   8: Test perf pmu format parsing                           : Ok
   9: Test dso data interface                                : Ok
  10: roundtrip evsel->name check                            : Ok
  11: Check parsing of sched tracepoints fields              : Ok
  12: Generate and check syscalls:sys_enter_open event fields: Ok
  13: struct perf_event_attr setup                           : Ok
  14: Test matching and linking mutliple hists               : Ok
  15: Try 'use perf' in python, checking link problems       : Ok
