Subject: automatic IRQ affinity for virtio V2
Date: Fri, 27 Jan 2017 09:16:28 +0100 [thread overview]
Message-ID: <1485504997-17584-1-git-send-email-hch@lst.de> (raw)
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 remove struct virtio_pci_vq_info
- improve probe error handling by unwinding step by step
- new patch to convert virtio-scsi
