Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. in this respin: 1) I kept removed the ack from Jason as I reworked the patch @Jason, the nature and goal of the patch did not really changed please can I get back your acked-by with these changes? 2) Rewording for warning messages Regards, Pierre Pierre Morel (2):

[PATCH v12 0/2] s390: virtio: let arch validate VIRTIO features
Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. I changed VIRTIO_F_IOMMU_PLATFORM to VIRTIO_F_ACCESS_PLATFORM I forgot in drivers/virtio/Kconfig, and put back the inclusion of virtio_config.h for the definition of the callback in arch/s390/mm/init.c I wrongly removed in the last series.

[PATCH v8 0/2] s390: virtio: let arch validate VIRTIO features
Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. in this respin: I use the original idea from Connie for an optional arch_has_restricted_memory_access. I renamed the callback accordingly, added the definition of ARCH_HAS_RESTRICTED_MEMORY_ACCESS inside the VIRTIO Kconfig and the selection in the PROTECTED_VIRTUALIZATION_GUEST config

Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. in this respin: The tests are back to virtio_finalize_features. No more argument for the architecture callback which only reports if the architecture needs guest memory access restrictions for VIRTIO. I renamed the callback to arch_has_restricted_virtio_memory_access, and the config

Hi all, I changed the patch subject to reflect the content, becoming more general. 1) I removed the ack from Christian and Jason even far as I understand they gave it for the functionality more than for the implementation. @Jason, @Christian, please can I get back your acked-by with these changes? 2) previous patch had another name: [PATCH v3 0/1] s390: virtio: let arch choose to

[PATCH v3 0/1] s390: virtio: let arch choose to accept devices without IOMMU feature
An architecture protecting the guest memory against unauthorized host access may want to enforce VIRTIO I/O device protection through the use of VIRTIO_F_IOMMU_PLATFORM. Let's give a chance to the architecture to accept or not devices without VIRTIO_F_IOMMU_PLATFORM.
