[PATCH v5 0/3] KVM: x86: tracepoint updates
Posted by Maxim Levitsky 2 months, 2 weeks ago
This patch series is intended to add some selected information
to the kvm tracepoints to make it easier to gather insights about
running nested guests.

This patch series was developed together with a new x86 performance analysis tool
that I developed recently (https://gitlab.com/maximlevitsky/kvmon)
which aims to be a better kvm_stat, and allows you at glance
to see what is happening in a VM, including nesting.

V5: rebased on top of recent changes

Best regards,
	Maxim Levitsky

  KVM: x86: add more information to the kvm_entry tracepoint
  KVM: x86: add information about pending requests to kvm_exit
    tracepoint
  KVM: x86: add new nested vmexit tracepoints
