[Qemu-devel] [PATCH 00/30] Introduction of IOMMUs into the memory API

[Paolo Bonzini <pbonzini@redhat.com>]

This is part 1 of the memory API updates for 1.6.  (Part 2 is the
introduction of get/set_owner, part 3 is the introduction of the
RCU-style flatview).

Compared to the first submissions, there are a few extra cleanup
patches, and address_space_rw/read/write grew a return value so
that the existing DMAContext API doesn't need to change.

Paolo

Alexey Kardashevskiy (1):
  memory: give name to every AddressSpace

Avi Kivity (5):
  memory: fix address space initialization/destruction
  memory: limit sections in the radix tree to the actual address space size
  memory: iommu support
  vfio: abort if an emulated iommu is used
  pci: use memory core for iommu support

David Gibson (1):
  memory: Add iommu map/unmap notifiers

Jan Kiszka (3):
  memory: Replace open-coded memory_region_is_romd
  memory: Rename readable flag to romd_mode
  memory: Introduce address_space_lookup_region

Paolo Bonzini (20):
  exec: remove obsolete comment
  exec: eliminate qemu_put_ram_ptr
  exec: make qemu_get_ram_ptr private
  exec: eliminate stq_phys_notdirty
  memory: assert that PhysPageEntry's ptr does not overflow
  memory: allow memory_region_find() to run on non-root memory regions
  memory: do not duplicate memory_region_destructor_none
  memory: make memory_global_sync_dirty_bitmap take an AddressSpace
  s390x: reduce TARGET_PHYS_ADDR_SPACE_BITS to 62
  memory: create FlatView for new address spaces
  memory: add address_space_valid
  memory: clean up phys_page_find
  memory: add address_space_translate
  memory: add return value to address_space_rw/read/write
  spapr: convert TCE API to use an opaque type

  dma: eliminate old-style IOMMU support
  spapr_vio: take care of creating our own AddressSpace/DMAContext
  dma: eliminate DMAContext
