[Qemu-devel] [PATCH 00/40] Memory-related changes sneak peek for 1.6 |
|
Date: |
Tue, 7 May 2013 16:16:38 +0200 |
Patches 1-10 are small changes, some of them bugfixes for the IOMMU
portion of the patches.
Patches 11-13 introduce three new address_space APIs and clean up
the dispatch logic a bit by removing memory_region_section_addr.
Patches 14-22 introduce IOMMU memory regions, convert sPAPR to the
new API, and finally eliminate DMAContext in favor of AddressSpace.
Patches 24-37 set an owner on all regions owned by hot-unpluggable
devices (and several others when that was easy), and add ref/unref
calls that keep the regions alive even if the owner is hot-unplugged.
Patches 38-40 make memory_region_find safe for usage outside the BQL.
These patches are also at git://github.com/bonzini/qemu.git, branch
iommu.
