Subject: [PATCH v4 0/2] x86/hvm/viridian: APIC assist
Date: Thu, 17 Mar 2016 08:37:31 +0000	[thread overview]
Message-ID: <1458203853-4441-1-git-send-email-paul.durrant@citrix.com> (raw)

This patch series enables use of the 'APIC assist' enlightenment in Xen.

See section of the Microsoft Hypervisor Top Level Function
Specification v4.0b at:


for more information.

Patch #1 modifies the viridian code to keep the guest APIC assist pages
mapped for the lifetime of the domain (and incorporates a straightforward
data-structure change).

Patch #2 adds a new viridian code and a configuration option to the
toolstack that, when enabled, allows the local APIC emulation to make use
the APIC assist pages.
