Subject: [PATCH v2 00/13] x86: CPUID and MSR policy marshalling support
Date: Fri, 13 Jul 2018 21:03:01 +0100	[thread overview]
Message-ID: <1531512194-6865-1-git-send-email-andrew.cooper3@citrix.com> (raw)

This series introduces libx86, a small shared library between the hypervisor
and libxc, and hypercalls to get full CPUID/MSR policies.  Future work will
implement XEN_DOMCTL_set_cpumsr_policy, after the auditing and comparison
logic is sorted.

In the meantime, the data marshalling logic is in a suitable state for review.

This series is based on staging, and can be found in git form here:

  x86/msr: Drop stale comment for vcpu_msrs.spec_ctrl
  libx86: Introduce libx86/cpuid.h
  libx86: Introduce libx86/msr.h and share msr_policy with userspace
  libx86: Introduce a helper to serialise cpuid_policy objects
  libx86: Introduce a helper to deserialise cpuid_policy objects
  x86: Introduce struct cpu_policy to refer to a group of individual policies

Roger Pau Monné (5):
  libx86: generate cpuid-autogen.h in the libx86 include dir
  libx86: Share struct cpuid_policy with userspace
  libx86: introduce a libx86 shared library
