Currently use of xen-hvmcrash will cause an immediate domain_crash() in
initialize_vp_assist() because it is called from viridian_load_vcpu_ctxt()
without having first cleared any previous mapping.
This patch makes initialize_vp_assist() responsible for clearing previous
mappings, if necessary.

The Hypervisor Top Level Functional Specification v5.0a states in section

The main version includes a major and minor version number and a build

Section 2.4.4 of the Hypervisor Top Level Functional Specification states
that enabling bit 10 in EDX of CPUID leaf 3 advertises to Windows a set

This patch advertises that bit and implements the MSRs such that Xen can

The current threshold before the guest issues the hypercall is, and always

The Hypervisor Top Level Functional Specification v5.0a has many differences
from previous versions and introduces whole new sections.
This patch:
- Updates the URL at the top of the source.
- Fixes up section references accordingly.
- Modifies the MSR naming convention in the code to match the s

These warnings can be useful when Microsoft updates Windows.
In the past there have been several cases when Windows erroneously uses
hypercalls and MSRs that should be gated on CPUID flags than Xen does
not set. The usual symptom is a guest crash with little or no information

This patchset is to introduce vIOMMU framework and add virtual VTD's
interrupt remapping support according "Xen virtual IOMMU high level
design doc V3"(https://lists.xenproject.org/archives/html/xen-devel/
2016-11/msg01391.html).

This patch is to add get_irq_info callback for platform implementation
to convert irq remapping request to irq info (E,G vector, dest, dest_mode

The BIOS reports the remapping hardware units in a platform to system software
through the DMA Remapping Reporting (DMAR) ACPI table.
To build DMAR table during domain construction, two fields are added to struct
acpi_config. One is dmar_flag which indicates whether interrupt rema

In previous patch, we introduce a common vIOMMU layer. In our design,
we create/destroy vIOMMU through DMOP interface instead of creating it
according to a config flag of domain. It makes it is possible
to create vIOMMU in device model or in tool stack.
The following toolstack cod
