[00/15] Start KernelShark v2 transformation

Message

Yordan Karadzhov Sept. 29, 2020, 1:41 p.m. UTC

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.


Yordan Karadzhov (VMware) (15):
  kernel-shark: split kernel-shark from trace-cmd repo
  kernel-shark: Version 1.2.0

  kernel-shark: Introduce libkshark-hash
  kernel-shark: Introduce Data streams
  kernel-shark: Add stream_id to kshark_entry
  kernel-shark: Integrate the stream definitions with the C API
  kernel-shark: Provide merging of multiple data streams
  kernel-shark: Integrate the stream definitions with data model
  kernel-shark: Use only signed types for model defs
  kernel-shark: Add ksmodel_get_bin()
  kernel-shark: Protect ksmodel_set_in_range_bining()
  kernel-shark: Add methods for time calibration
