perf tools: Add pid to struct thread

2013-08-27T14:05:53+00:00

Record pid on struct thread.  The member is named 'pid_' to avoid
confusion with the 'tid' member which was previously named 'pid'.

perf tools: struct thread has a tid not a pid

2013-07-12T16:53:50+00:00

As evident from 'machine__process_fork_event()' and
'machine__process_exit_event()' the 'pid' member of struct thread is
actually the tid.

Rename 'pid' to 'tid' in struct thread accordingly.

perf tools: Save parent pid in thread struct

2013-05-28T13:24:05+00:00

Information is available, so why not save it in case some command wants
to use it.

perf tools: do not flush maps on COMM for perf report

2012-10-22T15:55:53+00:00

This fixes a long-standing bug caused by the lack of separate COMM and EXEC
record types, which makes "perf report" lose track of symbols when a process
renames itself.

With this fix (suggested by Stephane Eranian), a COMM (rename) no longer
flushes the maps, which is the correct behavior.  An EXEC also no longer
flushes the maps, but this doesn't matter because as new mappings are created
(for the executable and the libraries) the old mappings are automatically
removed.  This is not by accident: the functionality is necessary because DLLs
can be explicitly loaded at any time with dlopen(), possibly on top of existing
text, so "perf report" handles correctly the clobbering of new mappings on top
of old ones.

An alternative patch (which I proposed earlier) would be to introduce a
separate PERF_RECORD_EXEC type, but it is a much larger change (about 300
lines) and is not necessary.

perf machine: Introduce find_thread method

2012-10-06T19:33:22+00:00

There are cases where we want just to find a thread if it exists
already, so provide a method for that.

While doing that start moving 'machine' methods to a separate file.

perf session: Move threads to struct machine

2011-11-28T12:35:31+00:00

The 'machine' abstraction was introduced with 'perf kvm' where we could
have samples for the host and multiple guests, but at the time we ended
up keeping the list of all machines threads all in
session->host_machine.

Move the threads rb_tree to struct machine to separate the namespaces.

perf threads: Move thread_map to separate file

2011-01-24T12:59:00+00:00

To untangle it from struct thread handling, that is tied to symbols, etc.

Right now in the python bindings I'm working on I need just a subset of
the util/ files, untangling it allows me to do that.

perf tools: Refactor all_tids to hold nr and the map

2011-01-04T02:24:16+00:00

So that later, we can pass the thread_map instance instead of
(thread_num, thread_map) for things like perf_evsel__open and friends,
just like was done with cpu_map.
