[Xen-devel] [PATCH v3 00/14] xen/arm: Properly disable M2P on Arm

Posted by Julien Grall 3 weeks ago
Hi all,

Arm never supported a M2P yet there are some helpers implemented to deal with
the common code. However, the implementation of mfn_to_gmfn is completely
bogus.

This series aims to properly disable the M2P on Arm. See patch #8 for the
rationale regarding the lack of M2P on Arm.

While looking at the code, I also continued to convert some code to use
typesafe MFN/GFN.

Cheers,

Julien Grall (14):
  xen/x86: Make mfn_to_gfn typesafe
  xen/x86: Use mfn_to_gfn rather than mfn_to_gmfn
  xen/grant-table: Make arch specific macros typesafe
  xen: Convert hotplug page function to use typesafe MFN
  xen: Convert is_xen_fixed_mfn to use typesafe MFN
  xen: Convert is_xen_heap_mfn to use typesafe MFN
  xen: Introduce HAS_M2P config and use to protect mfn_to_gmfn call
  xen: Remove mfn_to_gmfn macro
  xen/x86: mm: Re-implement set_gpfn_from_mfn() as a static inline
    function
  xen/x86: pv: Convert update_intpte() to use typesafe MFN
  xen/x86: p2m: Remove duplicate error message in p2m_pt_audit_p2m()
  xen/x86: p2m: Rework printk format in audit_p2m()
  xen/mm: Convert {s, g}et_gpfn_from_mfn() to use typesafe MFN
  xen/mm: Provide dummy M2P-related helpers when !CONFIG_HAVE_M2P
