Persistent Trigger page2 format: 31 24 23 16 15 8 7 0 Byte ----------------------------------------------- |PageType |PageNumber |Reserved |PageVersion| 0x00 ----------------------------------------------- |Reserved |ExtPageType | ExtPageLength | 0x04 ----------------------------------------------- | Reserved | NumMPIEventTriggers | 0x08 ----------------------------------------------- | MPIEventTriggerEntries | 0x0C | | 0xFC ----------------------------------------------- NumMPIEventTriggers: Number of MPI Event Trigger Entries currently stored in this page. If this is set to zero, there are no valid MPI-Event-Trigger entries available in this page. MPIEventTriggerEntry: - MPIEventCode [15:00] MPI Event code specified in MPI-Spec - MPIEventCodeSpecific [16:31] For Event Code “MPI2_EVENT_LOG_ENTRY_ADDED (0x0021)”, this field specifies the Log-Entry-Qualifier. For all other Event Codes, this field is reserved and not used Maximum of 20-event trigger entries can be stored in this page. During driver load: If MPIEvent trigger type bit is enabled in the Persistent Trigger Page0 then read the Persistent Trigger Page2 and update the ioc instances diag_trigger_event.EventTriggerEntry with Persistent Trigger Page2's MPIEventTriggerEntries. This will restores the MPIEvent trigger type's triggers which are enabled before. When user modifies the MPIEvent trigger type triggers: When user sets/clears the MPIEvent trigger type triggers then driver fisrt checks whether IOC firmware supports trigger pages support or not. if firmware supports these pages then driver enables the MPIEvent trigger type bit in Persistent Trigger Page0 (if it was not enabled before) and updates the user provided trigger values in Persistent Trigger Page2.
