/*
Roll minor version. Change how f/w revisions are stored. Add some defines to get max luns for a card. Make sure the RESULT_QUEUE_LEN is not less than 64- I've seen breakage with that. Move the temp port database stuff into the softc (ick). Remove most of the target mode stuff. Make xflist storage an external outer layer thing (since it will now be allocated based upon the maximum commands that this HBA can support rather than request queue size).

Core version 2.0 (platform version 1.0) rewrite of ISP driver. Some interace cleanups, some new common functions. The major impact that will be noticeable right away is that if you boot with not Fibre connected to the FC cards, you no longer hang indefinitely.

#define ISP_CORE_VERSION_MAJOR 2
Add support for 2 Gigabit cards (2300/2312). This necessitated a change in how interrupts are down- the 23XX has not only a different place to check for an interrupt, but unlike all other QLogic cards, you have to read the status as a 32 bit word- not 16 bit words. Rather than have device specific functions as called from the core module (in isp_intr), it makes more sense to have the platform/bus modules do the gruntwork of splitting out the isr, semaphore register and the first outgoing mailbox register (if needed) *prior* to calling isp_intr (if calling isp_intr is necessary at all).

Add support for 2 Gigabit cards (2300/2312). This necessitated a change in how interrupts are down- the 23XX has not only a different place to check for an interrupt, but unlike all other QLogic cards, you have to read the status as a 32 bit word- not 16 bit words. Rather than have device specific functions as called from the core module (in isp_intr), it makes more sense to have the platform/bus modules do the gruntwork of splitting out the isr, semaphore register and the first outgoing mailbox register (if needed) *prior* to calling isp_intr (if calling isp_intr is necessary at all).

Update from Matthew Jacob: Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies. Make sure we get a port database entry for the fabric name server. Preserve fabric logins if the device didn't change across fabric or port database changes, or the device has already logged into us (e.g., for target/initiator dual role devices like Veritas SANbox). Propagate class 3 service parameter changes where devices can change roles. Fix all occurrences of setting a sendmarker so that setting it for one bus on dual bus cards doesn't wipe a pending sendmarker for other busses on the same card :-;. Comments added and clarifications made in some of the target mode code.

*
* A few notes about some of these functions:
*
* ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
* The argument is a pointer to an integer which is the time, in microseconds,
* we should wait to see whether we have good link. This test, if successful,
* lets us know our connection topology and our Loop ID/AL_PA and so on.
* You can't get anywhere without this.
*
* ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
* all entities using the FC Generic Services subcommand GET ALL NEXT.
* For each found entity, an ISPASYNC_FABRICDEV event is generated (see
* below).
*
* ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
* topology is NL or FL port (private or public loop). Since the Qlogic f/w
* 'automatically' manages local loop connections, this function essentially
* notes the arrival, departure, and possible shuffling around of local loop
* entities. Thus for each arrival and departure this generates an isp_async
* event of ISPASYNC_PROMENADE (see below).

* Assumes locks are held.
*
* A few notes about some of these functions:
*
* ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
* occurred that invalidates the list of fabric devices known and/or
* the list of known loop devices. The argument passed is a pointer
* whose values are defined below (local loop change, name server
* change, other). 'Other' may simply be a LIP, or a change in
* connection topology.
*
* ISPASYNC_FABRIC_DEV announces the next element in a list of
* fabric device names we're getting out of the name server. The
* argument points to a GET ALL NEXT response structure. The list
* is known to terminate with an entry that refers to ourselves.
* One of the main purposes of this function is to allow outer
* layers, which are OS dependent, to set policy as to which fabric
* devices might actually be logged into (and made visible) later
* at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
* devices that we can log into (256 less 3 'reserved' for F-port
* topologies), and fabrics can grow up to 8 million or so entries
* (24 bits of Port Address, less a wad of reserved spaces), clearly
* we had better let the OS determine login policy.
*
* ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
* is an index into the portdb in the softc ('target'). Whether that entrie's
* valid tag is set or not says whether something has arrived or departed.
* The name refers to a favorite pastime of many city dwellers- watching
* people come and go, talking of Michaelangelo, and so on..
Add ISPCTL_RUN_MBOXCMD control op and ISPASYNC_UNHANDLED_RESPONSE async event.
2001-02-20 04:11:35 +03:00
*
* ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
* response queue entry not otherwise handled. The outer layer should
* return non-zero if it handled it. The 'arg' points to a (possibly only
* partially) massaged response queue entry (see the platform's
* ISP_UNSWIZZLE_RESPONSE macro).
Implement and use Fast Posting for both parallel && fibre. Redo a bit of the startup code. Implement a call to outer framework function so that asynchronous events can be handled (e.g., speed negotiation, target mode). Roll internal release tags.

*
*
* INLINE - platform specific define for 'inline' functions
*
Add support for 2 Gigabit cards (2300/2312). This necessitated a change in how interrupts are down- the 23XX has not only a different place to check for an interrupt, but unlike all other QLogic cards, you have to read the status as a 32 bit word- not 16 bit words. Rather than have device specific functions as called from the core module (in isp_intr), it makes more sense to have the platform/bus modules do the gruntwork of splitting out the isr, semaphore register and the first outgoing mailbox register (if needed) *prior* to calling isp_intr (if calling isp_intr is necessary at all).
2001-09-01 11:12:23 +04:00
* ISP_DMA_ADDR_T - platform specific dma address coookie- basically
* the largest integer that can hold the 32 or
* 64 bit value appropriate for the QLogic's DMA
* addressing. Defaults to u_int32_t.

* SNPRINTF(buf, bufsize, fmt, ...) snprintf
* STRNCAT(dstbuf, size, srcbuf) strncat
* USEC_DELAY(usecs) microsecond spindelay function
Finally fix this driver to be sensible about the ENDIAN dance. It's not quite simply a question of the Qlogic being little endian and having to have stuff swapped on big endian machines- it also has to do with the fact that the SBus and PCI DMA layouts are wierd with respect to this. At any rate, now finally fixed- works on Mac G4, tested it on a SS10 for sparc, checked on alpha to see if I've broken anything, and as soon as I get another spare afternoon I'll finally install a sparc64 version which should just work (as it'll be like the Mac).
