Re: [virtio-dev] Dirty Page Tracking (DPT)

Hi!

So, from the previous mails, it seems that monitoring the used ring
(and the packed descriptors) is a good first step in that direction,
as DPDK did. This way, the device does not need to worry about the
dirty page tracking using a bitmap and the PCI writes limitation, and
we can evaluate later the proposed alternatives:
* Alternate used descriptors in packed.
* vDPA interface for vDPA devices in a convenient format.

Any thoughts? Do you think that we should start with another way?

Thanks!
