perf build-id: Move build-id related functions to util/build-id.c

2014-11-05T13:14:07+00:00

It'd be better managing those functions in a separate place as
util/header.c file is already big.

It now exports following 3 functions to others:

  bool perf_session__read_build_ids(struct perf_session *session, bool with_hits);
  int perf_session__write_buildid_table(struct perf_session *session, int fd);
  int perf_session__cache_build_ids(struct perf_session *session);

perf tools: Add dsos__hit_all()

2014-07-23T14:25:40+00:00

Add ability to mark all dsos as hit.

This is needed in the case of Instruction Tracing.  It takes so long to
decode an Instruction Trace that it is not worth doing just to determine
which dsos are hit.  A later patch takes this into use.

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 session: Use session->fd instead of passing fd as argument

Using session->fd instead of passing fd as argument because it's always
session->fd that's passed as fd argument.

perf tools: Remove event types framework completely

2013-07-15T19:28:22+00:00

Removing event types framework completely. The only remainder (apart
from few comments) is following enum:

  enum perf_user_event_type {
    ...
    PERF_RECORD_HEADER_EVENT_TYPE           = 65, /* deprecated */
    ...
  }

It's kept as deprecated, resulting in error when processed in
perf_session__process_user_event function.
