[Qemu-devel] [PATCH qemu v4 0/3] fio-pci, spapr: Allow in-kernel TCE ops acceleration

[Alexey Kardashevskiy]

This is my current working tree to support kernel's
"powerpc/kvm/vfio: Enable in-kernel acceleration".

Changes:
v4:
* rebased on the latest upstream with IOMMU MR QOM and
VFIO initialization reordering

v3:
* fixed multiple architectures with respect to IOMMU MR
* removed sPAPRIOMMUMemoryRegion

v2:
* QOM'fy of IOMMUMemoryRegion
* fix comments from v1 review



This is based on sha1
6887dc6700 Peter Maydell "Merge remote-tracking branch 
'remotes/borntraeger/tags/s390x-20170718' into staging".

Please comment. Thanks.
