[PATCH 0/6] AMD Nested Virt Preparation
Posted by George Dunlap 2 weeks, 4 days ago
This series lays the groundwork for revamp of the AMD nested virt
functionality.  The first five patches are clean-ups or reorganizations
of existing code.  The final patch is the first major step towards making
the feature supportable: allowing Xen to refuse nested virt support if certain
hardware features are not present.

George Dunlap (6):
  xen/hvm: Convert hap_capabilities into a bitfield
  svm: Improve type of cpu_has_svm_feature
  xen/hvm: Move other hvm_function_table booleans into the caps bitfield
  nestedsvm: Disable TscRateMSR
  nestedsvm: Remove bogus debug message from nestedsvm_check_intercepts
  svm/nestedvm: Introduce nested capabilities bit
