Description:
This trigger page is used to store information about
MPI (IOC Status & LogInfo) triggers.
Driver Persistent Trigger Page-4 format:
-------------------------------------------------------
| 31 24 23 16 15 8 7 0| Byte
-------------------------------------------------------
| PageType | PageNumber | Reserved | PageVersion | 0x00
--------------------------------------------------------
| Reserved | ExtPageType | ExtPageLength | 0x04
--------------------------------------------------------
| Reserved | NumMpiTriggerEntries | 0x08
--------------------------------------------------------
| MPITriggerEntry[0] | 0x0C
--------------------------------------------------------
| … |
--------------------------------------------------------
| MPITriggerEntry[19] | 0xA4
--------------------------------------------------------
NumMpiTriggerEntries:
This field indicates number of MPI (IOC Status & LogInfo)
trigger entries stored in this page. Currently driver is supporting
a maximum of 20-MPI trigger entries.
MPITriggerEntry:
-----------------------------------------------------
| 31 16 15 0 |
-----------------------------------------------------
| Reserved | IOCStatus |
-----------------------------------------------------
| IOCLogInfo |
-----------------------------------------------------
IOCStatus => Status value from the IOC
IOCLogInfo => Specific value that supplements the IOCStatus.
During driver load:
If MPI trigger type bit is enabled in the Persistent
Trigger Page0 then read the Persistent Trigger Page4 and update the
ioc instances diag_trigger_mpi.MPITriggerEntry with Persistent
Trigger Page4's MPITriggerEntries. This will restores the
MPI trigger type's triggers which are enabled before.
When user modifies the MPI trigger type triggers:
When user sets/clears the MPI 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
MPI trigger type bit in Persistent Trigger Page0 (if it was not
enabled before) and updates the user provided trigger values in
Persistent Trigger Page4.
