[Xen-devel] [PATCH v7 00/12] x86: guest resource mapping

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

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

NOTE: This series is based on a master re-base of Juergen Gross's patch "xen: 
move
XENMAPSPACE_grant_table code into grant_table.c". For convenience the code is 
also available
on a branch at:

http://xenbits.xen.org/gitweb/?p=people/pauldu/xen.git;a=shortlog;h=refs/heads/ioreq11

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 (12):
  x86/mm: allow a privileged PV domain to map guest mfns
  x86/mm: add HYPERVISOR_memory_op to acquire guest resources
  tools/libxenforeignmemory: add support for resource mapping
  tools/libxenforeignmemory: reduce xenforeignmemory_restrict code
    footprint
  tools/libxenctrl: use new xenforeignmemory API to seed grant table
  x86/hvm/ioreq: rename .*pfn and .*gmfn to .*gfn
  x86/hvm/ioreq: use bool rather than bool_t
  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/hvm/ioreq: add a new mappable resource type...
