perf session: Move the event processing routines to session.c

2009-12-28T08:03:32Z

No need for an extra "data_map" file since the routines there operate mainly on a perf_session instance.

perf session: Adopt the sample_type variable

2009-12-14T16:34:56Z

All tools had copies, and perf diff would have to specify a sample_type_check method just for copying it.

perf session: Move the hist_entries rb tree to perf_session

2009-12-14T15:57:18Z

As we'll need to sort multiple times for multiple perf sessions, so that we can then do a diff.

perf session: Move the global threads list to perf_session

2009-12-14T15:57:16Z

So that we can process two perf.data files. We still need to add a O_MMAP mode for perf_session so that we can do all the mmap stuff in it.

perf session: Reduce the number of parms to perf_session__process_events

2009-12-14T15:57:16Z

By having the cwd/cwdlen in the perf_session struct and full_paths in perf_event_ops. Now its just a matter of passing the ops.

perf session: Register the idle thread in perf_session__process_events

2009-12-14T15:57:15Z

No need for all tools to register it and then immediately call perf_session__process_events.

perf session: Ditch register_perf_file_handler

2009-12-14T15:57:15Z

Pass the event_ops to perf_session__process_events instead. Also move the event_ops definition to session.h, starting to move things around to their right place, trimming the many unneeded headers we have.

perf session: Pass the perf_session to the event handling operations

2009-12-14T15:57:13Z

They will need it to get the right threads list, etc. Signed-off-by: Arnaldo Carvalho de Melo Cc: Frédéric Weisbecker Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Paul Mackerras LKML-Reference: <1260741029-4430-1-git-send-email-acme@infradead.org> Signed-off-by: Ingo Molnar

perf tools: Introduce perf_session class

2009-12-12T06:42:12Z

That does all the initialization boilerplate, opening the file, reading the header, checking if it is valid, etc. And that will as well have the threads list, kmap (now) global variable, etc, so that we can handle two (or more) perf.data files describing sessions to compare.

perf symbols: perf_header__read_build_ids() offset'n'size should be u64

2009-12-10T07:30:29Z

As off_t is a long, so breaking things on 32-bit land. Now buildids work on 32-bit land.
