Subject: [Qemu-devel] [RFC PATCH qemu v3 0/4] vfio: SPAPR IOMMU v2 (memory preregistration support)
Date: Tue, 14 Jul 2015 22:21:50 +1000

Yet another try, reworked the whole patchset.

Here are few patches to prepare an existing listener for handling memory
preregistration for SPAPR guests running on POWER8.

This used to be a part of DDW patchset but now is separated as requested.

Please comment. Thanks!

* removed incorrect "vfio: Skip PCI BARs in memory listener"
* removed page size changes from quirks as they did not completely fix
the crashes happening on POWER8 (only total removal helps there)
* added "memory: Add reporting of supported page sizes"

Alexey Kardashevskiy (4):
  memory: Add reporting of supported page sizes
  vfio: Use different page size for different IOMMU types
  vfio: Store IOMMU type in container
  vfio: spapr: Add SPAPR IOMMU v2 support (DMA memory preregistering)
