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 v5:
* Only minor modifications addressing issues pointed out by Steven in
his reviews of v4.
Changes is 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 is 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 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.
