Just to stress, cvq has a bunch of drawbacks. For example it is hard to access from the hypervisor since it's DMA from VF. This is why I think our direction should be to add a vq transport that does all config accesses over admin commands. Or maybe I'm wrong. But, let's distinguish between requirements, and between requirements and design. Getting supported counters is a requirement. Doing this over cvq is a design. Reducing MMIO registers is a requirement. OK? -- MST This publicly archived list offers a means to provide input to the OASIS Virtual I/O Device (VIRTIO) TC.
