perf options: Check v type in OPT_U?INTEGER

2010-05-17T18:43:38+00:00

To avoid problems like the one fixed by Stephane Eranian in 3de29ca, now
we'll got this instead:

	bench/sched-messaging.c:259: error: negative width in bit-field ‘’
	bench/sched-messaging.c:261: error: negative width in bit-field ‘’

Which is rather cryptic, but is how BUILD_BUG_ON_ZERO works, so kernel
hackers should be already used to this.

With it in place found some problems, fixed by changing the affected
variables to sensible types or changed some OPT_INTEGER to OPT_UINTEGER.

Next csets will go thru converting each of the remaining OPT_ so that
review can be made easier by grouping changes per type per patch.

perf tools: Use eprintf for pr_{err,warning,info} too

2010-03-12T09:28:36+00:00

Just like we do for pr_debug, so that we can have a single point
where to redirect to the currently used output system, be it
stdio or newt.

perf tools: Adjust some verbosity levels

2010-02-04T08:33:27+00:00

Not to pollute too much 'perf annotate' debugging sessions.

perf tools: Unify debug messages mechanisms

2009-10-23T06:22:47+00:00

We were using eprintf in some places, that looks at a global
'verbose' level, and at other places passing a 'v' parameter to
specify the verbosity level, unify it by introducing
pr_{err,warning,debug,etc}, just like in the kernel.

perf tools: Use kernel bitmap library

perf report: Adjust column width to the values sampled

2009-07-11T08:24:11+00:00

Auto-adjust column width of perf report output to the
longest occuring string length.

Example:

[acme@doppio pahole]$  perf report --sort comm,dso,symbol | head -13

    12.79%   pahole  /usr/lib64/libdw-0.141.so    [.] __libdw_find_attr
     8.90%   pahole  /lib64/libc-2.10.1.so        [.] _int_malloc
     8.68%   pahole  /usr/lib64/libdw-0.141.so    [.] __libdw_form_val_len
     8.15%   pahole  /lib64/libc-2.10.1.so        [.] __GI_strcmp
     6.80%   pahole  /lib64/libc-2.10.1.so        [.] __tsearch
     5.54%   pahole  ./build/libdwarves.so.1.0.0  [.] tag__recode_dwarf_type
[acme@doppio pahole]$

[acme@doppio pahole]$  perf report --sort comm,dso,symbol -d /lib64/libc-2.10.1.so | head -10

    21.92%   pahole  /lib64/libc-2.10.1.so  [.] _int_malloc
    20.08%   pahole  /lib64/libc-2.10.1.so  [.] __GI_strcmp
    16.75%   pahole  /lib64/libc-2.10.1.so  [.] __tsearch
[acme@doppio pahole]$

Also add these extra options to control the new behaviour:

  -w, --field-width

Force each column width to the provided list, for large terminal
readability.

  -t, --field-separator:

Use a special separator character and don't pad with spaces, replacing
all occurances of this separator in symbol names (and other output) with
a '.' character, that thus it's the only non valid separator.

perf_counter tools: Share rbtree.with the kernel

2009-07-01T20:37:22+00:00

The tools/perf/util/rbtree.c copy already drifted by three
csets:

 4b324126e0c6c3a5080ca3ec0981e8766ed6f1ee
 4c60117811171d867d4f27f17ea07d7419d45dae
 16c047add3ceaf0ab882e3e094d1ec904d02312d

So remove the copy and use the lib/rbtree.c directly, sharing
the source code while still generating a separate object file,
since tools/perf uses a far more agressive -O6 switch.
