This set introduces some tracing facilities to rtla tools: - Add the possibility to change the tracing_thresh to osnoise, allowing a fine tune of OS noise detection. - Add the auto-tracing feature (-a threshold us), which aims helping the first approach to a problem by setting common tracing features with a single parameter. - Add -e/--event option, allowing osnoise and timerlat to enable additional trace events via (possible multiple) -e sys:event options. - Add the --filter option to filter the previous -e event. - Add the --trigger option to allow the usage of tracing trigger of the previously set -e event. If the trigger is hist: one, rtla automatically saves the hist file associated with the -e event. And some more improvements: - Add --dma-latency option to tune exit from idle latencies - Some minor fixes Changes from V2: - Rebased to for-next - Add --dma-latency - Some more fixes Changes from V1: - Add -e to osnoise/timerlat hist - Add --trigger - Add --filter - Add support to save hist file - Function name refactoring Daniel Bristot de Oliveira (15): rtla/osnoise: Add support to adjust the tracing_thresh rtla/osnoise: Add an option to set the threshold rtla/osnoise: Add the automatic trace option rtla/timerlat: Add the automatic trace option rtla/trace: Add trace events helpers rtla: Add -e/--event support rtla/trace: Add trace event trigger helpers rtla: Add --trigger support rtla/trace: Add trace event filter helpers rtla: Add --filter support rtla/trace: Save event histogram output to a file rtla: Check for trace off also in the trace instance rtla/osnoise: Fix osnoise hist stop tracing message rtla/timerlat: Add --dma-latency option rtla: Tools main loop cleanup Documentation/tools/rtla/common_options.rst | 19 + .../tools/rtla/common_osnoise_options.rst | 10 + .../tools/rtla/common_timerlat_options.rst | 12 + tools/tracing/rtla/src/osnoise.c | 83 +++++ tools/tracing/rtla/src/osnoise.h | 8 + tools/tracing/rtla/src/osnoise_hist.c | 95 ++++- tools/tracing/rtla/src/osnoise_top.c | 91 ++++- tools/tracing/rtla/src/timerlat_hist.c | 108 +++++- tools/tracing/rtla/src/timerlat_top.c | 103 +++++- tools/tracing/rtla/src/trace.c | 345 ++++++++++++++++++ tools/tracing/rtla/src/trace.h | 23 ++ tools/tracing/rtla/src/utils.c | 33 ++ tools/tracing/rtla/src/utils.h | 1 + 13 files changed, 903 insertions(+), 28 deletions(-) -- 2.34.1
