| A D | sdei.rst | 84 - Event priority: ``SDEI_MAPF_CRITICAL`` or ``SDEI_MAPF_NORMAL``, as described
136 - ``SDEI_MAPF_NORMAL``: Marks the event as having *Normal* priority. This is
137 the default priority.
139 - ``SDEI_MAPF_CRITICAL``: Marks the event as having *Critical* priority.
181 - Install priority descriptors for Normal and Critical SDEI interrupts.
268 - The priority of the event (either Critical or Normal, as configured by the
269 platform at build-time) shouldn't cause priority inversion. This means:
271 - If it's of Normal priority, neither Normal nor Critical priority dispatch
274 - If it's of a Critical priority, no Critical priority dispatch must be
