perf tools: Introduce filename__read_int helper

2013-10-17T19:33:43+00:00

Just opens a file and calls atoi() in at most its first 64 bytes.

To read things like /proc/sys/kernel/perf_event_paranoid.

perf tools: Separate out GTK codes to libperf-gtk.so

2013-10-09T18:55:25+00:00

Separate out GTK codes to a shared object called libperf-gtk.so.  This
time only GTK codes are built with -fPIC and libperf remains as is.  Now
run GTK hist and annotation browser using libdl.

perf tools: Add possibility to specify mmap size

2013-10-09T14:24:20+00:00

Adding possibility to specify mmap size via -m/--mmap-pages
by appending unit size character (B/K/M/G) to the
number, like:
  $ perf record -m 8K ls
  $ perf record -m 2M ls

The size is rounded up appropriately to follow perf
mmap restrictions.

If no unit is specified the number provides pages as
of now, like:
  $ perf record -m 8 ls

perf util: Add parse_nsec_time() function

2013-08-07T20:35:26+00:00

The parse_nsec_time() function is for parsing a string of time into
64-bit nsec value.  It's a preparation of time filtering in some of perf
commands.

perf util: Move debugfs/tracing helper functions to util.c

2013-07-12T16:46:00+00:00

Since they're generic helpers move them to util.c so that they can be
used by others.

perf tools: Include termios.h explicitly

2013-07-08T20:36:05+00:00

Building perf for android fails because it can't find the definition of
struct winsize.

This definition is in termios.h, so I add this header to util.h to solve
the problem.

It is missed by commit '2c803e52' which moves get_term_dimensions() from
builtin-top.c to util.c, but missed to move termios.h header.

perf tools: Fix bug in isupper() and islower()

2013-05-28T13:23:51+00:00

One of the reasons 'perf test' is failing on Power appears to be due to
a bug in isupper().

isupper(c) and islower(c) should be checking 'c' against the mask 0x20.
Instead they are checking sane_ctype[c] which causes isupper() to be
true for lower case letters.
