I proposed getting rid of attrs_mask/device_admin_caps and instead
specify that e.g. feature bits 64 to 95 are reserved for management
purposes. Maybe just add a 32 bit register, or maybe "extended features"
with a selector and length like mmio and ccw already do, up to you.
I think Cornelia likes this suggestion too.
This would replace functionality of the
VIRTIO_ADMIN_DEVICE_CAPS_IDENTIFY/VIRTIO_ADMIN_DEVICE_CAPS_ACCEPT
commands and have the advantage of being generally well specified and
understood.
Is this acceptable? Or is there a reason the new commands are
preferable?
