[Bdadev-discuss] BDA and Power Management

[Robert S. <rob...@gm...>]

BTW, Colin, while I got you on the list: It appears your driver has no
support for power management (just like mine:(). Have you looked into this,
or do you know of a good resource? I tried reading the DDK documentation,
but it only left me confused :(

The key thing one has to do is to restore the hardware state after resuming
e.g. from hibernating (i.e. complete power-off). Now the ugly thing about
this is that if a BDA graph is running when you hibernate, it will only be
put in _paused_ state, not stopped! Thus, you need to get the hardware back
exactly to that paused state, which I think is rather complicated... Or
maybe there is a way to request that the graph is put in stopped state? I
haven't found any, though :(
