Subject: automatic IRQ affinity for virtio V3
Date: Sun, 5 Feb 2017 18:15:17 +0100 [thread overview]
Message-ID: <20170205171526.6224-1-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 V2:
- remove a redundant callback check
- calculate ->msix_vectors correctly
- add a few Reviewed-by: tags for Jason
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
