[Xen-devel] [PATCH v2 00/25] xen/x86: Per-domain CPUID policies

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Presented herewith is v2 of the first part of improvement work to support full
per-domain CPUID policies.  More work is pending on top of this series.

This series is available in git form from:

  
http://xenbits.xen.org/gitweb/?p=people/andrewcoop/xen.git;a=shortlog;h=refs/heads/xen-cpuid-v2

Testing wise, this series has been bisected, checking at each stage that the
guest-visibile CPUID information is identical (other than reported-frequency
values) for different VMs in a number of configurations.

All review comment from v1 have been addressed.  Headline changes are the
dynamic generation of bitfield names, and recalculation of policy in more
places.

Andrew Cooper (25):
  x86/cpuid: Introduce guest_cpuid() and struct cpuid_leaf
  x86/cpuid: Introduce struct cpuid_policy
  x86/cpuid: Move featuresets into struct cpuid_policy
  x86/cpuid: Allocate a CPUID policy for every domain
  x86/cpuid: Recalculate a domains CPUID policy when appropriate
  x86/hvm: Dispatch cpuid_viridian_leaves() from guest_cpuid()
  x86/cpuid: Dispatch cpuid_hypervisor_leaves() from guest_cpuid()
  x86/cpuid: Introduce named feature bitfields
  x86/hvm: Improve hvm_efer_valid() using named features
  x86/hvm: Improve CR4 verification using named features
  x86/vvmx: Use hvm_cr4_guest_valid_bits() to calculate MSR_IA32_VMX_CR4_FIXED1
  x86/pv: Improve pv_cpuid() using named features
  x86/hvm: Improve CPUID and MSR handling using named features
  x86/svm: Improvements using named features
  x86/pv: Use per-domain policy information when calculating the cpumasks
  x86/pv: Use per-domain policy information in pv_cpuid()
  x86/hvm: Use per-domain policy information in hvm_cpuid()
  x86/cpuid: Drop the temporary linear feature bitmap from struct cpuid_policy
  x86/cpuid: Calculate appropriate max_leaf values for the global policies
  x86/cpuid: Perform max_leaf calculations in guest_cpuid()
  x86/cpuid: Move all leaf 7 handling into guest_cpuid()
  x86/hvm: Use guest_cpuid() rather than hvm_cpuid()
  x86/svm: Use guest_cpuid() rather than hvm_cpuid()
  x86/cpuid: Effectively remove pv_cpuid() and hvm_cpuid()
  x86/cpuid: Alter the legacy-path prototypes to match guest_cpuid()
