perf evlist: Introduce perf_evlist__parse_sample

2012-08-02T14:42:57+00:00

That is a more compact form of perf_session__parse_sample and to support
multiple evlists per perf_session is the way to go anyway.

perf session: Use perf_evlist__id_hdr_size more extensively

2012-08-01T22:31:00+00:00

Removing perf_session->id_hdr_size, as it can be obtained from the
evsel/evlist.

perf evsel: Precalculate the sample size

2012-08-01T21:53:11+00:00

So that we don't have to store it in the perf_session instance, because
in the future perf_session instances may have multiple evlists, each
with different sample_type/sizes.

perf tools: Stop using a global trace events description list

2012-06-27T16:08:42+00:00

The pevent thing is per perf.data file, so I made it stop being static
and become a perf_session member, so tools processing perf.data files
use perf_session and _there_ we read the trace events description into
session->pevent and then change everywhere to stop using that single
global pevent variable and use the per session one.

Note that it _doesn't_ fall backs to trace__event_id, as we're not
interested at all in what is present in the
/sys/kernel/debug/tracing/events in the workstation doing the analysis,
just in what is in the perf.data file.

This patch also introduces perf_session__set_tracepoints_handlers that
is the perf perf.data/session way to associate handlers to tracepoint
events by resolving their IDs using the events descriptions stored in a
perf.data file. Make 'perf sched' use it.

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

2012-06-20T11:41:53+00:00

Pull perf improvements from Arnaldo Carvalho de Melo:

 * Replace event_name with perf_evsel__name, that handles the event
   modifiers and doesn't use static variables.

 * GTK browser improvements, from Namhyung Kim

 * Fix possible NULL pointer deref in the TUI annotate browser, from
   Samuel Liao

 * Add sort by source file:line number, using addr2line.

 * Allow printing histogram text snapshots at any point in top/report.

perf tools: Remove unused evsel parameter from machine__resolve_callchain

2012-06-19T16:06:21+00:00

Removing unused evsel parameter from machine__resolve_callchain
function. Plus related header file and callers changes.

The evsel parameter is unused since following commit:

perf tools: Fix endianity swapping for adds_features bitmask

2012-06-11T14:20:01+00:00

Based on Jiri's latest attempt:
https://lkml.org/lkml/2012/5/16/61

Basically, adds_features should be byte swapped assuming unsigned
longs are either 8-bytes (u64) or 4-bytes (u32).

    Fixes 32-bit ppc dumping 64-bit x86 feature data:
     ========
     captured on: Sun May 20 19:23:23 2012
     hostname : nxos-vdc-dev3
     os release : 3.4.0-rc7+

Verified 64-bit x86 can still dump feature data for 32-bit ppc.
