[Xen-devel] [PATCH v6 00/12] PVH VCPU hotplug support

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

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

Main changes in v6:
* Generate SCI on VCPU map update by domctl
* Simplify public domctl structure
* Make ACPI registers accessible only by guest (and not by domctl)
* Update VCPU map under lock
* Fix pointer update in xc_acpi_access()

Boris Ostrovsky (12):
  domctl: Add XEN_DOMCTL_acpi_access
  x86/save: public/arch-x86/hvm/save.h is available to hypervisor and
    tools only
  pvh/acpi: Install handlers for ACPI-related PVH IO accesses
  pvh/acpi: Handle ACPI accesses for PVH guests
  x86/domctl: Handle ACPI access from domctl
  events/x86: Define SCI virtual interrupt
  pvh: Send an SCI on VCPU hotplug event
  libxl: Update xenstore on VCPU hotplug for all guest types
  tools: Call XEN_DOMCTL_acpi_access on PVH VCPU hotplug
  pvh: Set online VCPU map to avail_vcpus
  pvh/acpi: Save ACPI registers for PVH guests
  docs: Describe PVHv2's VCPU hotplug procedure
