[Xen-devel] [PATCH v9 00/11] x86: guest resource mapping

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

This series introduces support for direct mapping of guest resources.
The resources are:
 - IOREQ server pages
 - Grant tables

v9:
 - Change to patch #1 only.

v8:
 - Re-ordered series and dropped two patches that have already been
   committed.

v7:
 - Fixed assertion failure hit during domain destroy.

v6:
 - Responded to missed comments from Roger.

v5:
 - Responded to review comments from Wei.

v4:
 - Responded to further review comments from Roger.

v3:
 - Dropped original patch #1 since it is covered by Juergen's patch.
 - Added new xenforeignmemorycleanup patch (#4).
 - Replaced the patch introducing the ioreq server 'is_default' flag with one
   that changes the ioreq server list into an array (#8).

Paul Durrant (11):
  x86/hvm/ioreq: maintain an array of ioreq servers rather than a list
  x86/hvm/ioreq: simplify code and use consistent naming
  x86/hvm/ioreq: use gfn_t in struct hvm_ioreq_page
  x86/hvm/ioreq: defer mapping gfns until they are actually requsted
  x86/mm: add HYPERVISOR_memory_op to acquire guest resources
  x86/hvm/ioreq: add a new mappable resource type...
  x86/mm: add an extra command to HYPERVISOR_mmu_update...
  tools/libxenforeignmemory: add support for resource mapping
  tools/libxenforeignmemory: reduce xenforeignmemory_restrict code
    footprint
  common: add a new mappable resource type: XENMEM_resource_grant_table
  tools/libxenctrl: use new xenforeignmemory API to seed grant table
