There is no way to get this information from the HAL. The driver in the
kernel is the only place that has global view on what is going out to
the hardware since that's where the mixing of the various clients
happens.
Plus, there are DRM issues that need to be resolved around vending out
the full mix of the device to just anyone. It's a matter still being
reviewed.
