      由 Arnaldo Carvalho de Melo 提交于 
      This patch also stops reading the common fields, as they were not being used except
for one ->common_pid case that was replaced by sample->tid, i.e. the info is already
in the perf_sample struct.

Also it only fills the _event structures when there is a handler.

    • I
      perf tools: Use __maybe_used for unused variables · 1d037ca1
      由 Irina Tirdea 提交于 
      perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored

__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.

The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

    • J
      perf tools: Back [vdso] DSO with real data · 7dbf4dcf
      由 Jiri Olsa 提交于 
      Storing data for VDSO shared object, because we need it for the post
unwind processing.

The VDSO shared object is same for all process on a running system, so
it makes no difference when we store it inside the tracer - perf.

When [vdso] map memory is hit, we retrieve [vdso] DSO image and store it
into temporary file.

During the build-id processing phase, the [vdso] DSO image is stored in
build-id db, and build-id reference is made inside perf.data. The
build-id vdso file object is called '[vdso]'. We don't use temporary
file name which gets removed when record is finished.

During report phase the vdso build-id object is treated as any other
build-id DSO object.

Adding following API for vdso object:

  bool is_vdso_map(const char *filename)
    - returns true if the filename matches vdso map name

  struct dso *vdso__dso_findnew(struct list_head *head)
    - find/create proper vdso DSO object

  vdso__exit(void)
    - removes temporary VDSO image if there's any

This change makes backtrace dwarf post unwind possible from [vdso] maps.

Following output is current report of [vdso] sample dwarf backtrace:

  # Overhead  Command      Shared Object                         Symbol
  # ........  .......  .................  .............................

      perf tools: Update types definitions for Android · 86d5a70c
      由 Irina Tirdea 提交于 
      Some type definitions are missing from Android or are already defined in
bionic and lead to redefinition errors.

Android defines in types.h __le32. Since perf is wrapping <linux/types.h> with a
local version, we need to define this constant in the local version too.
Error in Android:

__force macro defined in perf is also defined in libc which leads to
redefinition errors. In order to avoid these, we guard these definition

      perf tools: include wrapper for magic.h · f8fcd776
      由 Irina Tirdea 提交于 
      perf is currently including magic.h directly from the kernel. If the
glibc magic.h is also included, this leads to warnings that the
constants are redefined. This happens on some systems (e.g. Android).

Redefinition errors on Android:
In file included from util/util.h:79:0,
                 from util/cache.h:5,
                 from util/abspath.c:1:
util/../../../include/linux/magic.h:5:0:
error: "AFFS_SUPER_MAGIC" redefined [-Werror]
bionic/libc/include/sys/vfs.h:53:0:
note: this is the location of the previous definition
util/../../../include/linux/magic.h:19:0:
error: "EFS_SUPER_MAGIC" redefined [-Werror]
bionic/libc/include/sys/vfs.h:61:0:
note: this is the location of the previous definition
util/../../../include/linux/magic.h:26:0:
error: "HPFS_SUPER_MAGIC" redefined [-Werror]
bionic/libc/include/sys/vfs.h:67:0:
note: this is the location of the previous definition

Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and
SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only
these constants instead of including the kernel header file directly.
