Title 02771: Resolve VIRTIO-130: 4.1.4.5 ISR status capability diagram incorrect
Name * 02771: Resolve VIRTIO-130: 4.1.4.5 ISR status capability diagram incorrect (15K)
Description Please vote Yes if you agree with all of the following. If you disagree, please vote No. If you don't have an opinion, please vote Abstain. I move that: The TC agrees to resolve the following specification issue: VIRTIO-130: 4.1.4.5 ISR status capability diagram incorrect -------------------------------------- 4.1.4.5 ISR status capability diagram has the "Device Configuration Interrupt " as bit 0, and the "Queue Interrupt" as bit 1. This is the wrong way around: it disagrees with the legacy implementations, as well as the spec elsewhere: 4.1.5.3 Virtqueue Interrupts From The Device If an interrupt is necessary for a virtqueue, the device would typically act as follows: If MSI-X capability is disabled: Set the lower bit of the ISR Status field for the device. ... 4.1.5.4 Notification of Device Configuration Changes Some virtio PCI devices can change the device configuration state, as reflected in the device-specific configuration region of the device. In this case: If MSI-X capability is disabled: Set the second lower bit of the ISR Status field for the device. ... -------------------------------------- The TC accepts the following proposed changes to the specification: -------------------------------------- Reverse the two in the diagram. Patch on mailing list: https://lists.oasis-open.org/archives/virtio/201502/msg00033.html -------------------------------------- The TC agrees to include the above change(s) in specification version(s) "virtio 1.0 cs03", and future versions of the specification. -------------------------------------- Reminder: A Voting Member must be active in a TC to maintain voting rights. As the Virtio TC has adopted a standing rule to conduct business only by electronic ballot, without Meetings, a Voting Member who fails to cast a ballot in two consecutive Work Product Ballots loses his or her voting rights at the close of the second ballot missed. --------------------------------------
