* atrace: make fs-specific sysfs entries optionalGreg Hackmann2014-11-201-8/+8
| | | | | | | | | | 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. Bug: 18467498 Change-Id: I96200f1b5cf3f1a8fa8186602552adc96ddffc04 Signed-off-by: Greg Hackmann <ghackmann@google.com>
* 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: add memory reclaim tracingColin Cross2014-08-181-0/+6

* atrace: add support for app tracingJamie Gennis2013-03-281-3/+26
| | | | | | | | This change adds support for the -a command line argument to atrace. This argument sets the comma separated list of application names (i.e. /proc/self/cmdline values) for which to enable application-level tracing. Change-Id: I812d57c4cdc581943247229413f09b7e1adc10d0

| * atrace: add support for tracing kernel functionsJamie Gennis2013-03-181-28/+174
| | | | | | | | | | | | | | | | This change adds support for tracing specific kernel function calls using the function_graph tracer. It adds a '-k' option to atrace that accepts a comma separated list of kernel function names for which tracing will be enabled. Change-Id: I872b2f1d474b8ebb904053853fc8cf8c0a98089c

* atrace: clean up tracing option enablingJamie Gennis2012-12-072-232/+303
| | | | | | | | | 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

* atrace: make clock & bus bw tracing optionalJamie Gennis2012-10-051-18/+23
| | | | | | | | This change makes enabling clock tracing and bus bandwidth tracing depend on whether the device's kernel supports these features. If it's not supported it will be skipped. Change-Id: I51d57299693635b0ecebb75de5dccd5b62d47be3

* atrace: enable running on user buildsJamie Gennis2012-06-072-16/+37
| | | | | | | | | This change allows atrace to be run on a user build, where it is not run as root. Some command line options still require root, and atrace will refuse to run if those options are specified when run as non-root. Bug: 6513400 Change-Id: I29984cb8a7c3ad80ba5fa6b031ed8ff81acabacf

| | | | | | | This change adds the -i command line flag to atrace to enable tracing CPU idle kernel events. Change-Id: I4a2c8619224c0f50c7fd7c61c7b24fa2211f656c
* atrace: add support for zlib compressionJamie Gennis2012-04-282-7/+95
| | | | | | | This change adds the -z command line flag to atrace to enable support for compressing the trace with zlib as it's printed to stdout. Change-Id: I45301c63a4d1d388152244fec3c9e05e554598e8
* atrace: make cpu freq governor tracing optionalJamie Gennis2012-04-091-3/+11
| | | | | | | This change allows atrace to run on kernels that do not have CPU frequency interactive governor tracing enabled in the kernel. Change-Id: Ibfde751da7b6cc9a55794355093a37feb28f5e52
* atrace: add some more command line optionsJamie Gennis2012-03-071-1/+67
| | | | | | | | | This change adds two command line optiosn: -b for setting the trace buffer size -f for enabling tracing of the CPU frequency -l for enabling tracing of the CPU load Change-Id: Id99851a4c4eba5cfed218f29081e072bbe492133
