      perf test: Update command line callchain attribute tests · 46d525ea
      由 Arnaldo Carvalho de Melo 提交于 
      The "struct perf_event_attr setup" entry in 'perf test' is in fact a
series of tests that will exec the tools, passing different sets of
command line arguments to then intercept the sys_perf_event_open
syscall, in user space, to check that the perf_event_attr->sample_type
and other feature request bits are setup as expected.

We recently restored the callchain requesting command line argument, -g,
to not require a parameter ("dwarf" or "fp"), instead using a default
("fp" for now) and making the long option variant, --call-chain, be the
one to be used when a different callchain collection method is
preferred.

The "struct perf_event_attr setup" test failed because we forgot to
update the tests involving callchains, not switching from, '-g dwarf' to
'--call-chain dwarf', making 'perf test' detect it:

  [root@sandy ~]# perf test -v 13
  13: struct perf_event_attr setup                           :
  --- start ---
  running '/home/acme/libexec/perf-core/tests/attr/test-record-basic'
  running '/home/acme/libexec/perf-core/tests/attr/test-record-branch-any'
  <SNIP>
  running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-default'
  running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf'
  expected sample_type=12583, got 295
  expected exclude_callchain_user=1, got 0
  expected sample_stack_user=8192, got 0
  FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' - match failure
  ---- end ----
  struct perf_event_attr setup: FAILED!
  [root@sandy ~]#

Fix all of them now to use --call-chain when explicitely specifying a
method.

There is still work to do, as '-g fp', for instance, passed without
problems.

In that case 'perf test' saw no problems as the intercepted syscall got
the bits as expected, i.e. the default is 'fp', but the fact that 'fp'
may be an existing program and the specified workload would then be
passed as a parameter to it is an usability problem that needs fixing.

Next merge window tho.

    • S
      perf tools: Add attr->mmap2 support · 5c5e854b
      由 Stephane Eranian 提交于 
      This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.

It adds for each file-backed mapping the device major, minor number and
the inode number and generation.

This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.

The patch will prefer MMAP2 over MMAP.

[ Cope with 314add6b "Change machine__findnew_thread() to set thread pid",
  fix 'perf test' regression test entry affected,
  use perf_missing_features.mmap2 to fallback to not using .mmap2 in older kernels,
  so that new tools can work with kernels where this feature is not present ]
