perf tools: Get rid of redundant _FILE_OFFSET_BITS definition

2013-03-21T16:04:00+00:00

We define it in the Makefile so no need to duplicate it.

perf tools: Move ltrim() to util/string.c

2013-01-24T19:40:49+00:00

As we have ltrim() implementation in builtin-script.c move it to the
more generic location of util/string.c so that it can be used from other
places.

perf tools: Move get_term_dimensions from top to util.c

2013-01-24T19:40:34+00:00

It is used by util/help.c so it should be a lib function and included in
libperf.a. Code move only.

perf trace: Support interrupted syscalls

2012-10-24T19:23:03+00:00

Using the same strategies as in the tmp.perf/trace2, i.e. the 'trace'
tool implemented by tglx, just updated to the current codebase.

Example:

[root@sandy linux]# perf trace usleep 1  | tail

For now the timestamp and duration are always on, will be selectable.

Also if multiple threads are being monitored, its tid will appear.

The ret output continues to be interpreted a la strace.

perf tools: Have the page size value available for all tools

2012-10-06T19:33:14+00:00

Its such a common need that we might as well have a global with that
value.

perf tools: include wrapper for magic.h

2012-09-11T14:38:10+00:00

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.

perf tools: remove unneeded include of network header files

2012-09-05T20:45:12+00:00

perf does not have networking related functionality, and the inclusion
of these headers is one of the causes of compile failures for Android:

  https://lkml.org/lkml/2012/8/23/316
  https://lkml.org/lkml/2012/8/28/293

So, remove them.
