== Permissions ==
Each time permissions are checked, the [[#fsp-pr|process-obj]] is loaded using the session PID, then a func is called with the permissions-type. The func retval is checked, then the permissions [[Error_codes|error]] is thrown if needed.
Internally in that process-obj load func, it will load the obj as normal when the PID is >6, otherwise it will use a fixed obj. If not done already, that fixed obj will be initialized using fixed input data, via the same code used internally by [[#fsp-pr]].
In general this func uses the input permissions-type to determine what mask value to use. That value is masked with the [[NPDM|permissions]] from the above process-obj. When the result is 0, 0 is returned, otherwise non-zero is returned. The default non-zero retval is basically 0x3.
Panic is triggered when the input type is >0x26.
