Subject: [Xen-devel] [PATCH 0/6] tools: Rationalise legacy CPUID handling
Date: Wed, 5 Feb 2020 16:50:50 +0000	[thread overview]
Message-ID: <20200205165056.11734-1-andrew.cooper3@citrix.com> (raw)

This series attempts to remove some of the more insane behaviours from early
CPUID handling.  This is a little RFC to get a feel, but I intend to extend
the same kind of handling to ITSC (and get rid of nomigrate), and provide some
slightly nested-virt behaviour until it can become a domaincreate parameter.

Patch 1 has already been posted twice before.  Others are new.  I'm leaning
towards rebasing the libxl/migration work over this series, because it will
clean up a few of the transformation patches.

Andrew Cooper (6):
  tools/libxl: Remove libxl_cpuid_{set,apply_policy}() from the API
  tools/ocaml: Drop cpuid helpers
  tools/python: Drop cpuid helpers
  tools/libxl: Combine legacy CPUID handling logic
  tools/libx[cl]: Don't use HVM_PARAM_PAE_ENABLED as a function parameter
  xen/public: Obsolete HVM_PARAM_PAE_ENABLED
