the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have
a complete set of inline functions in isp_inline.h. Each platform is
responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32}
macros.
The reason this needs to be done is that we need to have a single set of
functions that will work correctly on multiple architectures for both little
and big endian machines. It also needs to work correctly in the case that
we have the request or response queues in memory that has to be treated
specially (e.g., have ddi_dma_sync called on it for Solaris after we update
it or before we read from it). It also has to handle the SBus cards (for
platforms that have them) which, while on a Big Endian machine, do *not*
require *most* of the request/response queue entry fields to be swizzled
or unswizzled.
One thing that falls out of this is that we no longer build requests in the
request queue itself. Instead, we build the request locally (e.g., on the
stack) and then as part of the swizzling operation, copy it to the request
queue entry we've allocated. I thought long and hard about whether this was
too expensive a change to make as it in a lot of cases requires an extra
copy. On balance, the flexbility is worth it. With any luck, the entry that
we build locally stays in a processor writeback cache (after all, it's only
64 bytes) so that the cost of actually flushing it to the memory area that is
the shared queue with the PCI device is not all that expensive. We may examine
this again and try to get clever in the future to try and avoid copies.
Another change that falls out of this is that MEMORYBARRIER should be taken
a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the
entry being added. But there had been many other places this had been missing.
It's now very important that it be done.
Additional changes:
Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry,
the iptr value that gets returned is the value we intend to eventually plug
into the ISP registers as the entry *one past* the last one we've written-
*not* the current entry we're updating. All along we've been calling sync
functions on the wrong index value. Argh. The 'fix' here is to rename all
'iptr' variables as 'nxti' to remember that this is the 'next' pointer-
not the current pointer.
Devote a single bit to mboxbsy- and set aside bits for output mbox registers
that we need to pick up- we can have at least one command which does not
have any defined output registers (MBOX_EXECUTE_FIRMWARE).

|

|
|
*
|
|
* 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).
|
|
*
|
|
* ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
|
|
* order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
|
|
* The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
|
|
* and logging out of fabric devices (if one is on a fabric) and then marking
|
|
* the 'loop state' as being ready to now be used for sending commands to
|
|
* devices. Originally fabric name server and local loop scanning were
|
|
* part of this function. It's now been separated to allow for finer control.

* 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..
|
|
*
|
|
* 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 an unmassaged
|
|
* response queue entry.
