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.

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,
