The way I see it, debugging facilities ideally would be somewhat separate from rest of the driver. For example, imagine an on-device gateway that lets you query the internal device state. Sounds better than trying to tweak registers that other driver parts might be tweaking at the same time, while trying to take locks that other driver parts might be holding at the same time. -- MST --------------------------------------------------------------------- To unsubscribe, e-mail: virtio-dev-unsubscribe@lists.oasis-open.org For additional commands, e-mail: virtio-dev-help@lists.oasis-open.org
