[Xen-devel] [PATCH 00/10] PVH VCPU hotplug support

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

This series adds support for ACPI-based VCPU hotplug for unprivileged
PVH guests.

New XEN_DOMCTL_set_avail_vcpus is introduced and is called during
guest creation and in response to 'xl vcpu-set' command. This domctl
updates GPE0's status and enable registers and sends an SCI to the
guest using (newly added) VIRQ_SCI.


Boris Ostrovsky (10):
  x86/domctl: Add XEN_DOMCTL_set_avail_vcpus
  acpi: Define ACPI IO registers for PVH guests
  pvh: Set online VCPU map to avail_vcpus
  acpi: Power and Sleep ACPI buttons are not emulated
  acpi: Make pmtimer optional in FADT
  acpi: PVH guests need _E02 method
  pvh/ioreq: Install handlers for ACPI-related PVH IO accesses
  pvh/acpi: Handle ACPI accesses for PVH guests
  events/x86: Define SCI virtual interrupt
  pvh: Send an SCI on VCPU hotplug event
