Message

Yordan Karadzhov Nov. 7, 2018, 4:14 p.m. UTC

This series of patches combines a development which originally aimed to
make the drawing logic of the Sched event plugin more robust and easy
to understand. It turned out that this is not possible without
introducing custom KernelShark entries for "Missed events".

Yordan Karadzhov (8):
  kernel-shark-qt: Reset the second pass hash when reloading Sched
    plugin
  kernel-shark-qt: Improve the plotting logic of the Sched event plugin
  kernel-shark-qt: Update the visualization model before plotting new
    graphs
  kernel-shark-qt: Add "Missed events" custom kshark_entry
  kernel-shark-qt: Add instrumentation for "Missed events" to the model
  kernel-shark-qt: Add tot_count field to the model descriptor
  kernel-shark-qt: Add "Missed events" plugin for KernelShark
  kernel-shark-qt: Update Sched Events plugin
