Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2011-10-26T15:03:38Z

* 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (121 commits) perf symbols: Increase symbol KSYM_NAME_LEN size perf hists browser: Refuse 'a' hotkey on non symbolic views perf ui browser: Use libslang to read keys perf tools: Fix tracing info recording perf hists browser: Elide DSO column when it is set to just one DSO, ditto for threads perf hists: Don't consider filtered entries when calculating column widths perf hists: Don't decay total_period for filtered entries perf hists browser: Honour symbol_conf.show_{nr_samples,total_period} perf hists browser: Do not exit on tab key with single event perf annotate browser: Don't change selection line when returning from callq perf tools: handle endianness of feature bitmap perf tools: Add prelink suggestion to dso update message perf script: Fix unknown feature comment perf hists browser: Apply the dso and thread filters when merging new batches perf hists: Move the dso and thread filters from hist_browser perf ui browser: Honour the xterm colors perf top tui: Give color hints just on the percentage, like on --stdio perf ui browser: Make the colors configurable and change the defaults perf tui: Remove unneeded call to newtCls on startup perf hists: Don't format the percentage on hist_entry__snprintf ... Fix up conflicts in arch/x86/kernel/kprobes.c manually. Ingo's tree did the insane "add volatile to const array", which just doesn't make sense ("volatile const"?). But we could remove the const *and* make the array volatile to make doubly sure that gcc doesn't optimize it away.. Also fix up kernel/trace/ring_buffer.c non-data-conflicts manually: the reader_lock has been turned into a raw lock by the core locking merge, and there was a new user of it introduced in this perf core merge. Make sure that new use also uses the raw accessor functions.

PM / Tracing: build rpm-traces.c only if CONFIG_PM_RUNTIME is set

2011-09-29T20:07:23Z

Do not build kernel/trace/rpm-traces.c if CONFIG_PM_RUNTIME is not set, which avoids a build failure. [rjw: Added the changelog and modified the subject slightly.] Signed-off-by: Ming Lei Signed-off-by: Rafael J. Wysocki

PM / Runtime: Introduce trace points for tracing rpm_* functions

2011-09-27T20:53:27Z

This patch introduces 3 trace points to prepare for tracing rpm_idle/rpm_suspend/rpm_resume functions, so we can use these trace points to replace the current dev_dbg(). Signed-off-by: Ming Lei Acked-by: Steven Rostedt Signed-off-by: Rafael J. Wysocki

tracing/filter: Add startup tests for events filter

2011-08-19T18:35:59Z

Adding automated tests running as late_initcall. Tests are compiled in with CONFIG_FTRACE_STARTUP_TEST option. Adding test event "ftrace_test_filter" used to simulate filter processing during event occurance. String filters are compiled and tested against several test events with different values. Also testing that evaluation of explicit predicates is ommited due to the lazy filter evaluation.

tracing: Fix TRACE_EVENT power tracepoint creation

2011-01-08T04:26:29Z

DEFINE_TRACE should also exist when CONFIG_EVENT_TRACING=n. Otherwise, setting only TRACEPOINTS=y is broken. Acked-by: Arjan van de Ven Signed-off-by: Mathieu Desnoyers LKML-Reference: <20101028153117.GA4051@Krystal> Signed-off-by: Steven Rostedt

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

2010-08-06T16:30:52Z

* 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (162 commits) tracing/kprobes: unregister_trace_probe needs to be called under mutex perf: expose event__process function perf events: Fix mmap offset determination perf, powerpc: fsl_emb: Restore setting perf_sample_data.period perf, powerpc: Convert the FSL driver to use local64_t perf tools: Don't keep unreferenced maps when unmaps are detected perf session: Invalidate last_match when removing threads from rb_tree perf session: Free the ref_reloc_sym memory at the right place x86,mmiotrace: Add support for tracing STOS instruction perf, sched migration: Librarize task states and event headers helpers perf, sched migration: Librarize the GUI class perf, sched migration: Make the GUI class client agnostic perf, sched migration: Make it vertically scrollable perf, sched migration: Parameterize cpu height and spacing perf, sched migration: Fix key bindings perf, sched migration: Ignore unhandled task states perf, sched migration: Handle ignored migrate out events perf: New migration tool overview tracing: Drop cpparg() macro perf: Use tracepoint_synchronize_unregister() to flush any pending tracepoint call ...

ftrace,kdb: Extend kdb to be able to dump the ftrace buffer

2010-08-05T14:22:23Z

Add in a helper function to allow the kdb shell to dump the ftrace buffer. Modify trace.c to expose the capability to iterate over the ftrace buffer in a read only capacity. Signed-off-by: Jason Wessel Acked-by: Steven Rostedt CC: Frederic Weisbecker

tracing: Remove sysprof ftrace plugin

2010-07-20T12:29:46Z

The sysprof ftrace plugin doesn't seem to be seriously used somewhere. There is a branch in the sysprof tree that makes an interface to it, but the real sysprof tool uses either its own module or perf events. Drop the sysprof ftrace plugin then, as it's mostly useless.

tracing: Remove ksym tracer

2010-07-15T21:59:33Z

The ksym (breakpoint) ftrace plugin has been superseded by perf tools that are much more poweful to use the cpu breakpoints. This tracer doesn't bring more feature. It has been deprecated for a while now, lets remove it. Signed-off-by: Frederic Weisbecker Cc: Steven Rostedt Cc: Prasad Cc: Ingo Molnar

tracing: Remove kmemtrace ftrace plugin

2010-06-09T15:31:22Z

We have been resisting new ftrace plugins and removing existing ones, and kmemtrace has been superseded by kmem trace events and perf-kmem, so we remove it.
