struct adapter_t - driver's initialization structure dpc_h : tasklet handle : pci configuration pointer for kernel : pointer to host structure of mid-layer : synchronization lock for mid-layer and driver : driver is quiescent for now. : number of commands pending in the driver : pointer to the bulk of SCBs pointers for IO : pool of free scbs for IO : lock for pool of free scbs : pending commands list : exclusion lock for pending commands list : list of completed commands : exclusion lock for list of completed commands : max sg elements supported : to convert kernel device addr to our devices. : raid adapter specific pointer : maximum channel number supported - inclusive : max target supported - inclusive : max lun supported - inclusive : unique identifier for each adapter : IRQ for this adapter : internal timeout value, (-1) means no timeout : buffer to issue internal commands : dma handle for the above buffer : SCB pointers for user cmds, common mgmt module : pool of SCBs for user commands : exclusion lock for these SCBs : max outstanding commands : firmware version : bios version : biggest CDB size supported. : is high availability present - clustering : initiator ID, the default value should be 7 : max sectors per request : max outstanding commands per LUN : set when unloading, no more mgmt calls
mraid_setup_device_map() can be called anytime after the device map is available and MRAID_GET_DEVICE_MAP() can be called whenever the mapping is required, usually from LLD's queue entry point. The formar API sets up the MRAID_IS_LOGICAL(adapter_t *, struct scsi_cmnd *) to find out if the device in question is a logical drive.
quiescent flag should be set by the driver if it is not accepting more commands
NOTE: The fields of this structures are placed to minimize cache misses
