Description

Please vote Yes if you agree with all of the following. If you disagree, please vote No. I move that: The TC agrees to resolve the following specification issue: VIRTIO-116: ccw transport needs to allow failing WRITE_STATUS -------------------------------------- The WRITE_STATUS ccw command needs to be able to fail, e.g. when the driver wants to set FEATURES_OK but the device can't work with the features. -------------------------------------- The TC accepts the following proposed changes to the specification: -------------------------------------- Failure scenarios for driver and device need to be documented: - driver must check for failures of WRITE_STATUS and treat device as unusable - device must post failure of WRITE_STATUS if the driver tries to set a wrong state Proposed patch: (updated) https://lists.oasis-open.org/archives/virtio/201502/msg00014.html Old proposal (listed here for completenes, please ignore for voting purposes): https://lists.oasis-open.org/archives/virtio/201410/msg00031.html -------------------------------------- The TC agrees to include the above change(s) in specification version(s) "virtio 1.0 cs03", and future versions of the specification.
