Since the Qlogic f/w 647 * 'automatically' manages local loop connections, this function essentially 648 * notes the arrival, departure, and possible shuffling around of local loop 649 * entities. Thus for each arrival and departure this generates an isp_async 650 * event of ISPASYNC_PROMENADE (see below). 651 * 652 * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in 653 * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP. 654 * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging 655 * and logging out of fabric devices (if one is on a fabric) and then marking 656 * the 'loop state' as being ready to now be used for sending commands to 657 * devices. Originally fabric name server and local loop scanning were 658 * part of this function. It's now been separated to allow for finer control. 659 */ 660typedef enum { 661 ISPCTL_RESET_BUS, /* Reset Bus */ 662 ISPCTL_RESET_DEV, /* Reset Device */ 663 ISPCTL_ABORT_CMD, /* Abort Command */ 664 ISPCTL_UPDATE_PARAMS, /* Update Operating Parameters (SCSI) */ 665 ISPCTL_FCLINK_TEST, /* Test FC Link Status */ 666 ISPCTL_SCAN_FABRIC, /* (Re)scan Fabric Name Server */ 667 ISPCTL_SCAN_LOOP, /* (Re)scan Local Loop */ 668 ISPCTL_PDB_SYNC, /* Synchronize Port Database */ 669 ISPCTL_SEND_LIP, /* Send a LIP */ 670 ISPCTL_GET_POSMAP, /* Get FC-AL position map */ 671 ISPCTL_RUN_MBOXCMD, /* run a mailbox command */ 672 ISPCTL_TOGGLE_TMODE, /* toggle target mode */ 673 ISPCTL_GET_PDB /* get a single port database entry */ 674} ispctl_t; 675int isp_control(ispsoftc_t *, ispctl_t, void *); 676 677 678/* 679 * Platform Dependent to Internal to External Control Function 680 * (each platform must provide such a function) 681 * 682 * Assumes locks are held. 683 * 684 * A few notes about some of these functions: 685 * 686 * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has 687 * occurred that invalidates the list of fabric devices known and/or 688 * the list of known loop devices. The argument passed is a pointer 689 * whose values are defined below (local loop change, name server 690 * change, other).

The 695 * argument points to a GET ALL NEXT response structure. The list 696 * is known to terminate with an entry that refers to ourselves. 697 * One of the main purposes of this function is to allow outer 698 * layers, which are OS dependent, to set policy as to which fabric 699 * devices might actually be logged into (and made visible) later 700 * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric 701 * devices that we can log into (256 less 3 'reserved' for F-port 702 * topologies), and fabrics can grow up to 8 million or so entries 703 * (24 bits of Port Address, less a wad of reserved spaces), clearly 704 * we had better let the OS determine login policy. 705 * 706 * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which 707 * is an index into the portdb in the softc ('target'). Whether that entry's 708 * valid tag is set or not says whether something has arrived or departed. 709 * The name refers to a favorite pastime of many city dwellers- watching 710 * people come and go, talking of Michaelangelo, and so on.. 711 * 712 * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a 713 * response queue entry not otherwise handled. The outer layer should 714 * return non-zero if it handled it. The 'arg' points to an unmassaged 715 * response queue entry. 716 */ 717 718typedef enum { 719 ISPASYNC_NEW_TGT_PARAMS, /* New Target Parameters Negotiated */ 720 ISPASYNC_BUS_RESET, /* Bus Was Reset */ 721 ISPASYNC_LOOP_DOWN, /* FC Loop Down */ 722 ISPASYNC_LOOP_UP, /* FC Loop Up */ 723 ISPASYNC_LIP, /* LIP Received */ 724 ISPASYNC_LOOP_RESET, /* Loop Reset Received */ 725 ISPASYNC_CHANGE_NOTIFY, /* FC Change Notification */ 726 ISPASYNC_FABRIC_DEV, /* FC Fabric Device Arrival */ 727 ISPASYNC_PROMENADE, /* FC Objects coming && going */ 728 ISPASYNC_TARGET_NOTIFY, /* target asynchronous notification event */ 729 ISPASYNC_TARGET_ACTION, /* target action requested */ 730 ISPASYNC_CONF_CHANGE, /* Platform Configuration Change */ 731 ISPASYNC_UNHANDLED_RESPONSE, /* Unhandled Response Entry */ 732 ISPASYNC_FW_CRASH, /* Firmware has crashed */ 733 ISPASYNC_FW_DUMPED, /* Firmware crashdump taken */ 734 ISPASYNC_FW_RESTARTED /* Firmware has been restarted */ 735} ispasync_t; 736int isp_async(ispsoftc_t *, ispasync_t, void *); 737 738#define ISPASYNC_CHANGE_PDB ((void *) 0) 739#define ISPASYNC_CHANGE_SNS ((void *) 1) 740#define ISPASYNC_CHANGE_OTHER ((void *) 2) 741 742/* 743 * Platform Dependent Error and Debug Printout 744 * 745 * Generally this is: 746 * 747 * void isp_prt(ispsoftc_t *, int level, const char *, ...) 748 * 749 * but due to compiler differences on different platforms this won't be 750 * formally done here.
