[Xen-devel] [PATCH 0/6] AMD-PVH: DomU support

[elena.ufimtseva@xxxxxxxxxx]

From: Elena Ufimtseva <elena.ufimtseva@xxxxxxxxxx>

This is a re-spin of patches for AMD PVH DomU from Mukesh Rathor.
As I am diving into more details of AMD PVH, I am reposting his series
with minor changes that reviewers (Jan and Boris) posted in comments.

The issue with handle_mmio is not yet addressed and I would like to
continue discussion Mukesh and Jan previously had in this thread
http://lists.xen.org/archives/html/xen-devel/2014-08/msg01760.html
The latest proposed solution was to create additional x86_emulate_ops structure
that will handle pvh mmio correctly.
Should I consider this approach as the one I should be working on?

In vmcb construction patch comments Roger suggested to add additional
parameter to vcpu_initialise as 32 bit work is in. Since Boris has 
posted 32-bit pvh domU support, that would be changed and I wanted to
see if this is what everyone agrees on.

Any other ideas/comments are also appreciated.
Thank you.

Changes made in this re-post:
 - left out setting LMA bit in construct_vmcb as its done in 
hvm_vcpu_initialise;
 - instead of checking if regs ptr is set in vcpu_vlapic, check if its 
pvh_domain;


Elena Ufimtseva (6):
  pvh: domu construct vmcb 64 bit mode start
  AMD-PVH: cpuid intercept
  AMD-PVH: call hvm_emulate_one instead of handle_mmio
  AMD-PVH: Do not get/set vlapic TPR
  AMD-PVH: Support TSC_MODE_NEVER_EMULATE for PVH
  AMD-PVH: enable pvh if requirements met
