Namhyung Kim b314e5cfd1 perf session: Fix infinite loop on invalid perf.data file
perf-record updates the header in the perf.data file at termination.
Without this update perf-report (and other processing built-ins) it
caused an infinite loop when perf report (or something like) called.

This is because the algorithm in __perf_session__process_events()
depends on the data_size which is read from file header.  Use file size
directly instead in this case to do the best-effort processing.

Stephane Eranian 5c5e854bc7 perf tools: Add attr->mmap2 support
This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.

It adds for each file-backed mapping the device major, minor number and
the inode number and generation.

This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.

The patch will prefer MMAP2 over MMAP.

Arnaldo Carvalho de Melo ccf53eac20 perf trace: Handle perf.data files with no tracepoints
Before:

  perf trace -i perf.data
  Segmentation fault (core dumped)
  #

After:

 # perf trace -i perf.data
 Data file does not have raw_syscalls:sys_enter events
 #

When there are no tracepoints in a perf.data file the struct pevent
that contains the list of tracepoints that will be used to lookup the
tracepoint id by name will not be populated, causing a NULL deref.

And we don't need to do all that dance to look at pevents for an entry
with a slighly different name to then lookup the tracepoint by its id on
the evlist, just use the perf_evlist__find_tracepoint_by_name() routine,
that will find the tracepoint, if present.

Jiri Olsa 526fd8d4f7 perf session: Separate progress bar update when processing events
Currently when processing events in the __perf_session__process_events
function we update a progress bar based on the file_size. During the
same processing we update the progress bar from within
flush_sample_queue which is based on number of samples count.

Having 2 different based updates is causing the progress bar to jump
heavily back and forth giving not much usefull info.

Fixing this by keeping only __perf_session__process_events based
progress bar update. And turning on flush_sample_queue progress bar
update only for final flushing.

This reduces the number of time the progress bar update function is
called and it significantly reduces the loading time for TUI, where the
progress bar update takes quite a lot of time.

David Ahern 0b8c25d949 perf tools: Fix symbol offset computation for some dsos
For some dsos (e.g., libc, libpthread, kernel modules) the symbol offset
is huge. e.g.,

    ffffffff816288a1 __schedule+0x451 ([kernel.kallsyms])

It seems to be maps with a non-0 start. Taking that into account the

Adrian Hunter 314add6b1f perf tools: change machine__findnew_thread() to set thread pid
Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

Note that callers sometimes want to find the main thread
which has the memory maps.  The main thread has tid == pid
so the usage in that case is:

	machine__findnew_thread(machine, pid, pid)

whereas the usage to find the specific thread is:

	machine__findnew_thread(machine, pid, tid)

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

Jiri Olsa 6065210db9 perf tools: Remove event types framework completely
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.
