[Qemu-devel] [PATCH v8 0/4] vfio on spapr-ppc64

[Alexey Kardashevskiy]

Yet another try with VFIO on SPAPR (server PPC64).

This adds VFIO support on SPAPR for the existing VFIO-SPAPR-TCE driver
in the upstream kernel.

Individual patches have more detailed commit logs.

Please comment. Thanks!


Changes:
v8:
* added placeholder for KVM_CAP_SPAPR_TCE_VFIO capability
* added generic helper to call ioctl on container's fd.

v7:
* cleaned and rebased on agraf/ppc-next tree (which is on its way to upstream)

v6:
* initial set was split into 3

v5:
* rebase on top of the current upstream

v4:
* addressed all comments from Alex Williamson
* moved spapr-pci-phb-vfio-phb to new file
* split spapr-pci-phb-vfio to many smaller patches
