Subject: [Qemu-devel] [PATCH v2 00/11] Memory patches, part 4: region ownership
Date: Fri, 28 Jun 2013 18:58:11 +0200 [thread overview]
Message-ID: <1372438702-20491-1-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
v1->v2: patches 7/11 redone and placed at the end of the series; refcount
changes for address_space_translate left for a later series, they
are not yet necessary; rebased on top of Jan's patches.
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: 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
exec: reorganize address_space_map
memory: ref/unref memory across address_space_map/unmap
