perf tools: Configurable per thread proc map processing time out

2015-06-19T21:27:13+00:00

The time out to limit the individual proc map processing was hard code
to 500ms. This patch introduce a new option --proc-map-timeout to make
the time limit configurable.

perf auxtrace: Add support for AUX area recording

2015-04-29T13:37:51+00:00

Add support for reading from the AUX area tracing mmap and synthesizing
AUX area tracing events.

This patch introduces an abstraction for recording AUX area data.

Recording is initialized by auxtrace_record__init() which is a weak
function to be implemented by the architecture to provide recording
callbacks.

Recording is mainly handled by auxtrace_mmap__read() and
perf_event__synthesize_auxtrace() but there are callbacks for
miscellaneous needs including validating and processing user options,
populating private data in auxtrace_info_event, and freeing the
structure when finished.

perf record: Add clockid parameter

2015-04-08T13:04:55+00:00

Teach perf-record about the new perf_event_attr::{use_clockid, clockid}
fields. Add a simple parameter to set the clock (if any) to be used for
the events to be recorded into the data file.

Since we store the entire perf_event_attr in the EVENT_DESC section we
also already store the used clockid in the data file.

perf: Bump max number of cpus to 1024

2015-03-26T13:52:28+00:00

SPARC based systems currently support up to 1024 cpus (e.g. T5-8).
Allow perf to work on those systems.

perf record: Support recording running/enabled time

2015-02-25T15:42:23+00:00

Add an option to perf record to record running/enabled time for read
events, similar to what stat does.

This is useful to understand multiplexing problems.

Right now the report support is not great, but at least report -D
already supports it.

perf tools: Export usage string and option table of perf record

2014-10-29T12:32:47+00:00

Those are shared with other builtin commands like kvm, script.  So
make it accessable from them.  This is a preparation of later change
that limiting possible options.

perf tools: Move callchain config from record_opts to callchain_param

2014-09-26T15:40:33+00:00

So that all callchain config parameters can be read/written to a single
place.  It's a preparation to consolidate handling of all callchain
options.
