[Qemu-devel] [PATCH qemu v5 0/2] vfio-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:
v5:
* changed IOMMU MR callbacks and reworked the whole thing as
David suggested

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
e040047a4d Greg Kurz "spapr: sanity check size of the CAS buffer".

Please comment. Thanks.
