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 in v7: * Patches 1-5 are new, but these are only infrastructureal changes that have no functional effects on the API. - License info is added. - README is updated. - KernelShark now builds and links against the stand-alone versions of libtraceevent and libtracefs. Changes in v6: * The patches from the "OpenGL wrapper" patch-set (already reviewed by Steven) have been added here (patches 21-24). * Patches 25-27 are new, but these are only infrastructureal changes that have no functional effects on the API. Changes in v5: * Only minor modifications addressing issues pointed out by Steven in his reviews of v4. Changes in v4: * The integer data format identifier is replaced with a string value that gets registered by the readout plugin. * Plus several small modifications addressing the issues pointed out by Steven. Changes in v3. This version contains number of small modifications addressing the issues pointed out by Steven in his review. However, it also contains the following major changes: * The session context (kshark_context) holds a pointer to unspecified data processing interface (void *interface). This will allow to easily introduce new versions of this interface in the future, while keeping the interface that we have now for backward compatibility. The necessary type checking when using the interface made the helper functions wrapping the corresponding methods of the interface relatively complicated, so the implementations have been moved from the header to the source file. * A more sophisticated management of the Data stream descriptors that can handle the case when Data streams are constantly added and removed has been implemented. The design for this change was suggested by Steven in his review. Changes in 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.
