Will reply with a link to the associated kernel series.
Changelog v4->v5:
- Update to match latest interface from kernel code. Major changes are:
1) we no longer issue any ioctls to set a device to interpreted mode;
rather, this will be done automatically if supported by the host kernel
at the time the vfio group is associated with the KVM. Then, the SHM
bit setting will indicate whether or not interpretation is actually
used.
2) the RPCIT enhancments (IOMMU changes) are removed from this series,
so the code associated with indicating a desired IOMMU are also
removed. With this series s390x-pci will continue to use only type1
IOMMU for now.
- Refresh the linux headers sync. Added a patch to tolerate some vfio
uapi renames that will happen in 5.18 (this can be discarded if there
is something else underway to address this)
