In this patch-set we are starting the introduction of the changes in the C API of libkshark. The goal of this transformation is to turn KernelShark into a general purpose toolkit for analysis of tracing data that is no longer strongly coupled to the Ftrace/trace-cmd data format. At the end of the transformation KernelShark will be able to merge and simultaneously visualize data from different tracers, recorded in different data formats. It will also significantly extend the possibilities for user customization. This patch-set transforms the way KernelShark processes the raw tracing data. Later, in a consecutive patch-sets we will introduce the changes in the visualization instruments and in the KernelShark GUI itself. Changes is v2: * Tried to address review comments for "kernel-shark: Introduce libkshark-hash" * The huge patch "kernel-shark: Integrate the stream definitions with the C API" in the previous version is now split into 8 smaller patches. The last of these 8 new patches (kernel-shark: Complete the stream integration) is still a bit entangled. I can try to further break this patch in future versions of the patch-set, if this is needed. Steven, Please review very carefully patches: kernel-shark: Introduce Data streams kernel-shark: Add basic methods for Data streams kernel-shark: Add stream interface for trace-cmd data kernel-shark: Start using data streams kernel-shark: Provide merging of multiple data streams kernel-shark: Add methods for time calibration Please review VERY carefully patche: kernel-shark: Redesign the plugin interface You may treat this one as a complete rewrite. Also it may be useful to see how the redesigned code is being used in the new version of the sched_events plugin here: https://github.com/yordan-karadzhov/kernel-shark-v2.beta/blob/master/src/plugins/sched_events.c https://github.com/yordan-karadzhov/kernel-shark-v2.beta/blob/master/src/plugins/SchedEvents.cpp Thanks!
