* DO NOT MERGE: add support for new sched tracepointTim Murray2015-11-301-0/+1
| | | | | | | | | This tracepoint gives systrace the means to display the reason for uninterruptible sleep. bug 23350688 Change-Id: I9ee5b6904c27bcb5bd67c86fda66d45d0a3c0999
* Map realtime to clock_monotonic.Martijn Coenen2015-08-311-3/+21
| | | | | | | | | | | | | | This maps a monotonic timestamp to the corresponding real-time timestamp, which can be used to match up the traces with other logs that use real-time. Also write clock_sync records first instead of at the end, to avoid not being to write it due to the buffer being full. Bug: 23668823 Change-Id: I644aeea496197e194ec30f808f754e3e043d905f

* Added Voltage and Current regulator ftrace events to atraceAaron Schulman2015-05-071-0/+3
| | | | | | | | | | | | | | | | | | | | Cherry-pick of c2c6ecd1195481f5813a721a7d20a73c0795c135 from AOSP Tracing the state of the voltage and current regulators enables a developer to attribute power consumption measurements to specific perhipherals and cores. Unlike other indirect methods of tracing when peripherals and cores are toggled, the regulator ftrace event indicates the exact point in time when the kernel switches on or off the device. For example, in the following trace, a developer can see exactly when the krait2 core starts receiving power, and and when the voltage is set for voltage scaling. mpdecision-2172 [000] ...1 1566.665481: regulator_enable: name=krait2 mpdecision-2172 [000] ...1 1566.665493: regulator_enable_delay: name=krait2 mpdecision-2172 [000] ...1 1566.665495: regulator_enable_complete: name=krait2 <...>-4133 [002] ...1 1566.666891: regulator_set_voltage: name=krait2 (1075000-1100000) Change-Id: Ia322206ef74496daf1d9baa03545d8e89e398487 Signed-off-by: Aaron Schulman <aschulman@google.com>

| | | | | | | | | | | | | | | | | | | | The availability of these sysfs entries will vary based on the kernel's supported filesystems, so don't block the disk category if some of them are missing.

* | atrace: fix Sync Manager tracing preventing enabling of kernel sync tracingPatrick Auchter2014-10-271-1/+1
|/ | | | | | | | | | | Both Sync Manager tracing and kernel sync tracing were using "sync" to enable tracing and since Sync Manager was found first, this prevented enabling kernel sync tracing. To fix this, use "syncman" to enable Sync Manager tracing. Change-Id: Id3b799e01e5041c582cd752c8c40d3e36954f821 Signed-off-by: Iliyan Malchev <malchev@google.com>
* atrace: avoid unnecessary writes to trace_clockColin Cross2014-08-201-1/+46
| | | | | | | | | | | | | Writing to trace_clock erases the trace buffer, even if the value hasn't changed. This prevents use of --async_start and --async_dump to leave background tracing running and dump after an even that needs debugging, because --async_dump writes to trace_clock and resets the buffer before it can read it. Read and parse the current value from trace_clock before writing, and skip the write if the value isn't changing. Change-Id: Ia2ec5bb654fb0bd179771b511ff261731ba47dca

* atrace: clean up tracing option enablingJamie Gennis2012-12-071-0/+711
This change switches atrace to use a table-driven approach to enabling and disabling options. It unifies how framework and kernel tracing are enabled, and causes userland tracing options to be picked up by currently running processes. Change-Id: Iba2a3012ca0a67c4defdd076bce597db26e9f539
