[Xen-devel] [PATCH v2 0/2] Support of RO MMCFG access for PVH/HVMlite dom0s

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

v2:
* Expanded npfec structure to include page's precense indicator (I took the
  easy way out and didn't implement VMX's fine-grained status since I couldn't
  figure out how to properly do it in SVM)
* s/mmio/mmcfg for some operations. I left mmio_ro_emulate_ctxt as is because
  it is used for non-MMCFG accesses
* Properly initialized hvm_emulate_ctxt (set data pointer after
  hvm_emulate_prepare())
* Added error handling to _hvm_emulate_one()
* Tested for page presence (and whether it is being written) before trying to
  emulate hvm access
* Added generic unhandleable_rwx() to x86_emulate.c
* Left non-MMCFG RO accesses unhandled (we havent't encountered those accesses
  yet with PVH dom0 and it's probably better to fault on them and investigate
  whether they are guest's issues).
* Code style updates

Boris Ostrovsky (2):
  x86/mm: Add information about faulted page's presence to npfec
    structure
  x86/PCI: Intercept Dom0 MMCFG from dom0s in HVM containers
