Hi Michael, this series contains a couple cleanups for the virtio_pci interrupt handling code, including a switch to the new pci_irq_alloc_vectors helper. All these are in preparation of taking advantage of the new PCI layer / core IRQ interrupt affinity handling, for which I will send out a series once this and some core interrupt handling changes are in.

Hi Michael, hi Jason, This patches applies a few cleanups to the virtio PCI interrupt handling code, and then converts the virtio PCI code to use the automatic MSI-X vectors spreading, as well as using the information in virtio-blk and virtio-scsi to automatically align the blk-mq queues to the MSI-X vectors. Changes since V1: - dropped the patches already merged for 4.10-rc - new patch to

Hi Michael, this series contains a couple cleanups for the virtio_pci interrupt handling code, including a switch to the new pci_irq_alloc_vectors helper, and support for automatic affinity by the PCI layer if the consumers ask for it. It then converts over virtio_blk to use this functionality so that it's blk-mq queues are aligned to the MSI-X vector routing. I have a similar patch in the

Hi, This is an initial implementation of a vhost-user backend for the VirtIO RPMB device. The device is currently in the draft of the next VirtIO specification and describes block device which uses combination of a key, nonce, hashing and a persistent write counter to prevent replay attacks (hence Replay Protected Memory Block). It is implemented as a vhost-user device because we want to
