[PATCH v2 0/2] virtio-blk: add iothread-vq-mapping parameter

2023-09-18 Thread Stefan Hajnoczi
virtio-blk and virtio-scsi devices need a way to specify the mapping between IOThreads and virtqueues. At the moment all virtqueues are assigned to a single IOThread or the main loop. This single thread can be a CPU bottleneck, so it is necessary to allow finer-grained assignment to spread the
