The kernel issues this call in order to instruct the display driver to change the display mode. The appropriate driver should respond by changing to the requested mode and setting R4 to 0 to claim the call.
The default claimant of this call is the kernel. If the call is left unclaimed the kernel will claim it and call HAL_Video_SetMode?.
