Here is another take on iommu_ops on POWER to make VFIO work again on POWERPC64. Tested on PPC, kudos to Fred! The tree with all prerequisites is here: https://github.com/aik/linux/tree/kvm-fixes-wip The previous discussion is here: https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20220707135552.3688927-1-aik@ozlabs.ru/ https://patchwork.ozlabs.org/project/kvm-ppc/patch/20220701061751.1955857-1-aik@ozlabs.ru/ https://lore.kernel.org/all/20220714081822.3717693-3-aik@ozlabs.ru/T/ Please comment. Thanks. This is based on sha1 ce888220d5c7 Linus Torvalds "Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi". Please comment. Thanks.
