perf tests: Switch from open to openat

2015-05-29T15:43:41+00:00

Multiple perf tests fail on arm64 due to missing open syscall:

 2: detect open syscall event                              : FAILED!

open(2) is a legacy syscall, replaced with openat(2) since 2.6.16.  Thus
new architectures in kernel, such as arm64, don't implement these legacy
syscalls.

The patch replaces all sys_enter_open events with sys_enter_openat,
renames the related tests and test output to avoid confusion.

perf tools: Add ARM64 perf_regs_load to support libunwind and enable testing

2015-05-29T15:43:40+00:00

Newest libunwind does support ARM64, and perf is able to utilize it
also.

This patch enables the perf test dwarf unwind for arm64.

 Test result:
  # ./perf test unwind
  25: Test dwarf unwind                                      : Ok

perf tests: Fix to get negative exit codes

2015-05-12T12:59:50+00:00

WEXITSTATUS consists of the least significant 8 bits of the status
argument, so we should convert the value to signed char if we have valid
negative exit codes. And the return value of test->func() contains
negative values:

  enum {
          TEST_OK   =  0,
          TEST_FAIL = -1,
          TEST_SKIP = -2,
  };

Before this patch:

  $ perf test -v 1
  ...
  test child finished with 254
  ---- end ----
  vmlinux symtab matches kallsyms: FAILED!

After this patch:

  $ perf test -v 1
  ...
  test child finished with -2
  ---- end ----
  vmlinux symtab matches kallsyms: Skip

perf tools: Add kmod_path__parse function

2015-03-21T17:53:41+00:00

Provides united way of parsing kernel module path
into several components.

The new kmod_path__parse function and few defines:

  int __kmod_path__parse(struct kmod_path *m, const char *path,
                         bool alloc_name, bool alloc_ext);

  #define kmod_path__parse(__m, __p)      __kmod_path__parse(__m, __p, false, false)
  #define kmod_path__parse_name(__m, __p) __kmod_path__parse(__m, __p, true , false)
  #define kmod_path__parse_ext(__m, __p)  __kmod_path__parse(__m, __p, false, true)

parse kernel module @path and updates @m argument like:

  @comp - true if @path contains supported compression suffix,
          false otherwise
  @kmod - true if @path contains '.ko' suffix in right position,
          false otherwise
  @name - if (@alloc_name && @kmod) is true, it contains strdup-ed base name
          of the kernel module without suffixes, otherwise strudup-ed
          base name of @path
  @ext  - if (@alloc_ext && @comp) is true, it contains strdup-ed string
          the compression suffix

It returns 0 if there's no strdup error, -ENOMEM otherwise.

perf tools: Add the bash completion for listing subsubcommands of perf test

2015-03-19T16:52:54+00:00

The bash completion does not support listing subsubcommands for 'perf
test ', so fix it.

Example:

Before this patch:

 $ perf test 
 $

As shown above, the subsubcommands of perf test does not come out.

After this patch:

 $ perf test 
 list

As shown above, the subsubcommands of perf test can come out now.

perf tools: Remove hists from evsel

2014-10-14T20:32:52+00:00

Now tools that deals want to have an hists per evsel need to call
hists__init() before creating any evsels, which can be as early as when
parsing the command line, so do it before calling parse_options().

The current tools using hists/hist_entries are report, top and annotate,
change them to request per evsel hists.

This is in preparation for making evsels usable by 3rd party tools, that
not necessarily live in perf's source code repository.

tools lib api: Adopt fdarray class from perf's evlist

2014-09-25T19:46:55+00:00

The extensible file description array that grew in the perf_evlist class
can be useful for other tools, as it is not something that only evlists
need, so move it to tools/lib/api/fd to ease sharing it.

v2: Don't use {} like in:

 libapi_dirs:
	$(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/

in Makefiles, as it will not work in some systems, as in ubuntu13.10.

v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa)

v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to
    be checked if it is really needed there, but has no place in the
    fdarray class (Fix from Jiri Olsa)

v5: Remove evlist details from fdarray grow/filter tests. Improve it a
    bit doing more tests about expected internal state.
