+/*
+ * the rough idea:
+ * init:
+ * miniport driver defines entrypoint thusly:
+ * ULONG DriverEntry(PVOID Context1, PVOID Context2);
+ * miniport allocates and initializes a VIDEO_HW_INIT_DATA struct
+ * miniport calls VideoPortInitialize
+ * video port driver handles init of DriverObject (Context1)
+ * video port driver calls back into HwVidFindAdapter entry point
+ * video port driver finishes up and returns the status code that
+ * the miniport driver should return.
+ * io requests:
+ * video port driver reformats IRP into VRP
+ * video port driver calls back into HwVidStartIO entry point
+ * minimum IoControlCodes that must be handles by the miniport:
+ * IOCTL_VIDEO_QUERY_NUM_AVAIL_MODES
+ * IOCTL_VIDEO_QUERY_AVAIL_MODES
+ * IOCTL_VIDEO_SET_CURRENT_MODE
+ * IOCTL_VIDEO_MAP_MEMORY
+ * IOCTL_VIDEO_RESET_DEVICE
+ * interrupts are handled the same as KM drivers.
