Subject: [PATCH v7 0/2] s390: virtio: let arch validate VIRTIO features
Date: Wed, 15 Jul 2020 10:31:07 +0200
Message-ID: <1594801869-13365-1-git-send-email-pmorel@linux.ibm.com> (raw)

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


Pierre Morel (2):
  virtio: let arch validate VIRTIO features
  s390: virtio: PV needs VIRTIO I/O device protection

to v7:

- typo in warning message
to v6:

- rewording warning messages
  (Connie, Halil)

to v5:

- return directly from S390 arch_validate_virtio_features()
  when the guest is not protected.

- Somme rewording
  (Connie, Michael)

- moved back code from arch/s390/ ...kernel/uv.c to ...mm/init.c

to v4:

- separate virtio and arch code

- moved code from arch/s390/mm/init.c to arch/s390/kernel/uv.c
  (as interpreted from Heiko's comment)

- moved validation inside the arch code

- moved the call to arch validation before VIRTIO_F_1 test

to v3:

- add warning
  (Connie, Christian)

- add comment

- change hook name
  (Halil, Connie)

to v2:

- put the test in virtio_finalize_features()

- put the test inside VIRTIO core

- pass a virtio device as parameter
