Currently the VPU firmware prepares for D0i3 every time the VPU is entering D0i2 Idle state. This is not optimal as we might not enter D0i3 every time we enter D0i2 Idle and this preparation is quite costly. This optimization moves D0i3 preparation to a dedicated message sent from the host driver only when the driver is about to enter D0i3 - this reduces power consumption and latency for certain workloads, for example audio workloads that submit inference every 10 ms. The VPU needs non zero time to enter IDLE state after responding to D0i3 entry message. If the driver does not wait for the VPU to enter IDLE state it could cause warm boot failures.
