Generally, I think that DirectFB API usage should be stopped by the application prior to system/SoC power entering a standby/suspended state, but for a robust solution when usage still occurs it should be handled. I am curious what the "preferred" approach is for applications using the DirectFB API when the system/SoC power is in a standby/suspended state. Should requests of the graphics driver block on access to the GPU unit and thus in essence hide the concept of power management (PM) from the application? Of course, that will not allow for the application to respond normally to requests to change behavior or exit cleanly, or handle emergency shutdown needs in a nice manner... Or should requests of the graphics driver return failures to the DFB core which will eventually bubble back out of the DFB API to the caller to handle?
