[Qemu-devel] [PATCH v3 0/3] trace: Add events to track vCPU lifecycle

[Lluís Vilanova]

Adds events to track vCPU hot-(un)plugging and reset.

As a bonus, first patch fixes per-vCPU dynamic event state initialization,
making the current late initialization code obsolete.

NOTE: This series is missing CPU hot-unplug, since I could not find a generic
  point to hook the event.

Changes in v3
=

* Remove code for trace_fini_vcpu(), since there is no full support for
  hot-unplugging.


Changes in v2
=

* Properly support vCPU hot-plugging to "inherit" dynamic event states.
* Rename event "guest_cpu_init" to "guest_cpu_enter".


Lluís Vilanova (3):
  trace: Properly initialize dynamic event states in hot-plugged vCPUs
  trace: Add event "guest_cpu_enter"
  trace: Add event "guest_cpu_reset"
