Hello,
Commit a940904443e432623579245babe63e2486ff327b ("powerpc/iommu: Add
iommu_ops to report capabilities and allow blocking domains") fixes a
regression that prevents attaching PCI devices to the vfio-pci driver on
PPC64. Its inclusion in 6.1 would open the door for restoring VFIO and
KVM PCI passthrough support on distros that rely on this LTS kernel.
Thanks,
Shawn

Given that the commit does NOT apply to the 6.1.y kernel tree, how was
this tested?
if you want it applied, please provide a working, and tested, backport.
thanks,
