Subject: [Qemu-devel] [PATCH 00/11] Memory patches, part 4: region ownership
Date: Tue, 25 Jun 2013 13:13:16 +0200	[thread overview]
Message-ID: <1372158807-19715-1-git-send-email-pbonzini@redhat.com> (raw)

This series, split out of the previous attempt to set owners for memory
regions, adds reference counting operations to memory regions and uses
them.  As requested by Peter, I'm adding an argument for the owner to
all memory region creation functions.

The big patches to actually add the owners will come soon, since I
found a decent way to split it.

Paolo

Paolo Bonzini (11):
  memory: add owner argument to initialization functions
  memory: destroy phys_sections one by one
  exec: simplify destruction of the phys map
  memory: add getter for owner
  memory: add ref/unref
  memory: add ref/unref calls
  exec: add a reference to the region returned by address_space_translate
  exec: check MRU in qemu_ram_addr_from_host
  exec: move qemu_ram_addr_from_host_nofail to cputlb.c
  memory: return MemoryRegion from qemu_ram_addr_from_host
  memory: ref/unref memory across address_space_map/unmap
