      perf tests: Add platform dependency to test 15 · 19508c04
      由 Thomas Richter 提交于 
      This patch adds platform dependency into the test case 15
(perf_event_attr). It is based on a suggestion from Jiri Olsa.

Add a new optional attribute named 'arch' in the [config] section of the
test case file. It is a comma separated list of architecture names this
test can be executed on. For example:

  arch = x86_64,alpha,ppc

If this attribute is missing the test is executed on any platform.  This
does not break existing behavior.

The values listed for this attribute should be identical to uname -m
output.

If the list starts with an exclamation mark (!) the comparison is
inverted, for example for

  arch = !s390x,ppc

the test is not executed on s390x or ppc platforms.  The exclamation
mark must be at the beginnning of the list.

Here is an example debug output:

  [root@s35lp76]# fgrep arch tests/attr/test-stat-C2
  arch = x86_64,alpha,ppc
  [root@s35lp76]# PERF_TEST_ATTR=/tmp /usr/bin/python2 ./tests/attr.py \
    -d ./tests/attr/ -p ./perf -vvvvv -t test-stat-C1

provides the following output:

  running './tests/attr//test-stat-C1'
  test limitation 'x86_64,alpha,ppc' <--- new
    loading expected events
      Event event:base-stat
        fd = 1
        group_fd = -1
        .....

Here is the output when a test is skipped:

  [root@s35lp76]# fgrep arch tests/attr/test-stat-C1
  arch = !s390x
  [root@s35lp76]# PERF_TEST_ATTR=/tmp /usr/bin/python2 ./tests/attr.py \
    -d ./tests/attr/ -p ./perf -vvvvv -t test-stat-C1

provides the following output:

test limitation '!s390x' <--- new

skipped [s390x] './tests/attr//test-stat-C1' <--- new

The test is skipped with return code 0.

      perf tests: Adjust some message log levels to help diagnosing problems in attr tests · ce90e385
      由 Arnaldo Carvalho de Melo 提交于 
      Now we'll see the command being run and if it fails, the fields that had
unexpected values and the expected values, example testing a problem in the
next patch:

  # perf test -v 13
  13: struct perf_event_attr setup                           :
  --- start ---
  SNIP
    running 'PERF_TEST_ATTR=/tmp/tmpDNIE6M /home/acme/bin/perf record -o /tmp/tmpDNIE6M/perf.data --group -e cycles,instructions kill >/dev/null 2>&1' ret 0
    running 'PERF_TEST_ATTR=/tmp/tmpV5lKro /home/acme/bin/perf stat -o /tmp/tmpV5lKro/perf.data -dd kill >/dev/null 2>&1' ret 1
  expected config=3, got 65540
  expected exclude_guest=1, got 0
  FAILED '/home/acme/libexec/perf-core/tests/attr/test-stat-detailed-2' - match failure
  ---- end ----
  struct perf_event_attr setup: FAILED!
  #

While in the past we would see at the '-v' level many more messages for the
fields that matched, something we may want to see only in the '-vv' log level.

Keeping the 'running' messages so that we can see the tools tests that
succeeded so that we can compare it to the one that failed, helping pinpointing
the command line switch combo that leads to the problem.
