Message

Yordan Karadzhov Jan. 8, 2021, 2:31 p.m. UTC

We implement a general purpose instruments, that can be used to
implement efficient (fast) visualization plugins. We also use
the new instrumentation to optimize the sched_events plugin.

Changes in v3:
 * Typo fixes in [patch 2]
 * The missing signed-off-by of [patch 3] is restored.

Changes in v2:
 * KS_DOUBLE_SIZE macro was simplified, based on the suggestion made by
   Steven in his review. A dedicated test case for the macro has been added.
 * Bug fix in kshark_free_data_container().
 * Bug fix in kshark_data_container_append().


Yordan Karadzhov (VMware) (6):
  kernel-shark: Add KS_DOUBLE_SIZE macro
  kernel-shark: Add kshark_data_container to libkshark
  kernel-shark: Add KS_DEFINE_PLUGIN_CONTEXT macro
  kernel-shark: Start using C++17
  kernel-shark: Add plotting methods to KsPlugins
  kernel-shark: Speed-up the sched_events plugin
