[PATCH 0/3] KVM: qemu patches for few KVM features I developed

Posted by Maxim Levitsky 2 years, 7 months ago

These patches implement the qemu side logic to support
the KVM features I developed recently.

First two patches are for features that are already accepted
upstream, and I already posted them on the qemu mailing list once.

And the 3rd patch is for nested TSC scaling on SVM
which isn't yet accepted in KVM but can already be added to qemu since
it is conditional on KVM supporting it, and ABI wise it only relies
on SVM spec.

Best regards,
    Maxim Levitsky

Maxim Levitsky (3):
  KVM: use KVM_{GET|SET}_SREGS2 when supported.
  gdbstub: implement NOIRQ support for single step on KVM
  KVM: SVM: add migration support for nested TSC scaling
