tools: Consolidate types.h

2014-05-01T19:22:39+00:00

Combine all definitions into a common tools/include/linux/types.h and
kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper
bitmap.h header.

perf tools: Parse tracepoints with '-' in system name

2014-04-29T12:27:23+00:00

Trace events potentially can have a '-' in their trace system name,
e.g. kvm on s390 defines kvm-s390:* tracepoints.
We could not parse them, because there was no rule for this:
  $ sudo ./perf top -e "kvm-s390:*"
  invalid or unsupported event: 'kvm-s390:*'

This patch adds an extra rule to event_legacy_tracepoint which handles
those cases. Without the patch, perf will not accept such tracepoints in
the -e option.

perf parse events: Demystify memory allocations

2013-07-12T16:52:05+00:00

List heads are currently allocated way down the function chain in
__add_event and add_tracepoint and then freed when the scanner code
calls parse_events_update_lists.

Be more explicit with where memory is allocated and who should free it. With
this patch the list_head is allocated in the scanner code and freed when the
scanner code calls parse_events_update_lists.

perf tools: Fix build with bison 2.3 and older.

2013-02-14T19:12:34+00:00

The %name-prefix "prefix" syntax is not available on bison 2.3 and
older. Substitute with the -p "prefix" command-line option for
compatibility with older versions of bison.

This patch fixes this build error with older versions of bison.

perf tools: Keep group information

2013-01-31T16:07:43+00:00

Add a few of group-related field in struct perf_{evlist,evsel} so that
the group information in a evlist can be known easily.  It only counts
groups which have more than 1 members since leader-only groups are
treated as non-group events.

perf tools: Fix usage of __ in event parsing struct names

2013-01-24T19:40:51+00:00

In tools/perf we use a convention where __ separates the struct name
from the function name for functions that operate on a struct instance.

Fix this usage by removing it from the struct names and fix also the
associated functions.

perf tools: Add support to specify hw event as PMU event term

2012-10-24T08:41:27+00:00

Add a way to specify hw event as PMU event term like:

 'cpu/event=cpu-cycles/u'
 'cpu/event=instructions,.../u'
 'cpu/cycles,.../u'

The 'event=cpu-cycles' term is replaced/translated by the hw events
term translation, which is exposed by sysfs 'events' group attribute.

Add parser bits, the rest is already handled by the PMU alias code.

perf tools: Use __maybe_used for unused variables

2012-09-11T15:19:15+00:00

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.

perf tools: Catch event names from command line

2012-08-22T16:40:49+00:00

Use command line string provided by the -e option to name events. This
way we get unique events names that also support pmu event syntax
(//). No need to reconstruct the name
anymore from its attributes. We use the event_desc of the header to
store the name in the perf.data header. Thus it is also available for
perf report.

Implemented by putting the parser in different states to parse events or
configs.

And since event names are now generated from the command line
specification.  Update event names in test cases accordingly.
