/*
|
|
|
|
|
* The Qlogic driver gets an interrupt to look at response queue entries.
|
|
|
|
|
* Some of these are status completions for initiatior mode commands, but
|
|
|
|
|
* if target mode is enabled, we get a whole wad of response queue entries
|
|
|
|
|
* to be handled here.
|
|
|
|
|
*
|
|
|
|
|
* Basically the split into 3 main groups: Lun Enable/Modification responses,
|
|
|
|
|
* SCSI Command processing, and Immediate Notification events.
|
|
|
|
|
*
|
|
|
|
|
* You start by writing a request queue entry to enable target mode (and
|
|
|
|
|
* establish some resource limitations which you can modify later).
|
|
|
|
|
* The f/w responds with a LUN ENABLE or LUN MODIFY response with
|
|
|
|
|
* the status of this action. If the enable was successful, you can expect...
|
|
|
|
|
*
|
|
|
|
|
* Response queue entries with SCSI commands encapsulate show up in an ATIO
|
|
|
|
|
* (Accept Target IO) type- sometimes with enough info to stop the command at
|
|
|
|
|
* this level. Ultimately the driver has to feed back to the f/w's request
|
|
|
|
|
* queue a sequence of CTIOs (continue target I/O) that describe data to
|
|
|
|
|
* be moved and/or status to be sent) and finally finishing with sending
|
|
|
|
|
* to the f/w's response queue an ATIO which then completes the handshake
|
|
|
|
|
* with the f/w for that command. There's a lot of variations on this theme,
|
|
|
|
|
* including flags you can set in the CTIO for the Qlogic 2X00 fibre channel
|
|
|
|
|
* cards that 'auto-replenish' the f/w's ATIO count, but this is the basic
|
|
|
|
|
* gist of it.
|
|
|
|
|
*
|
|
|
|
|
* The third group that can show up in the response queue are Immediate
|
|
|
|
|
* Notification events. These include things like notifications of SCSI bus
|
|
|
|
|
* resets, or Bus Device Reset messages or other messages received. This
|
2001-02-06 09:25:10 +00:00
|
|
|
* a classic oddbins area. It can get a little weird because you then turn
|
2000-01-04 00:00:08 +00:00
|
|
|
* around and acknowledge the Immediate Notify by writing an entry onto the
|
|
|
|
|
* request queue and then the f/w turns around and gives you an acknowledgement
|
|
|
|
|
* to *your* acknowledgement on the response queue (the idea being to let
|
|
|
|
|
* the f/w tell you when the event is *really* over I guess).

Major restructuring for swizzling to the request queue and unswizzling from
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).

-----------
MISC CHANGES
Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee
eventual delivery of a NOTIFY ACK. This is tons better than just
ignoring the return from isp_notify_ack and hoping for the best.
Clean up the lower level lun enable code to be a bit more sensible.
Fix a botch in isp_endcmd which was messing up the sense data.
Fix notify ack for SRR to use a sensible error code in the case
of a reject.
Clean up and make clear what kind of firmware we've loaded and
what capabilities it has.
-----------
FULL (252 byte) SENSE DATA
In CTIOs for the ISP, there's only a limimted amount of space
to load SENSE DATA for associated CHECK CONDITIONS (24 or 26
bytes). This makes it difficult to send full SENSE DATA that can
be up to 252 bytes.
Implement MODE 2 responses which have us build the FCP Response
in system memory which the ISP will put onto the wire directly.
On the initiator side, the same problem occurs in that a command
status response only has a limited amount of space for SENSE DATA.
This data is supplemented by status continuation responses that
the ISP pushes onto the response queue after the status response.
We now pull them all together so that full sense data can be
returned to the periph driver.
This is supported on 23XX, 24XX and 25XX cards.
This is also preparation for doing >16 byte CDBs.
-----------
FC TAPE
Implement full FC-TAPE on both initiator and target mode side. This
capability is driven by firmware loaded, board type, board NVRAM
settings, or hint configuration options to enable or disable. This
is supported for 23XX, 24XX and 25XX cards.
On the initiator side, we pretty much just have to generate a command
reference number for each command we send out. This is FCP-4 compliant
in that we do this per ITL nexus to generate the allowed 1 thru 255
CRN.
In order to support the target side of FC-TAPE, we now pay attention
to more of the PRLI word 3 parameters which will tell us whether
an initiator wants confirmed responses. While we're at it, we'll
pay attention to the initiator view too and report it.
On sending back CTIOs, we will notice whether the initiator wants
confirmed responses and we'll set up flags to do so.
If a response or data frame is lost the initiator sends us an SRR
(Sequence Retransmit Request) ELS which shows up as an SRR notify
and all outstanding CTIOs are nuked with SRR Received status. The
SRR notify contains the offset that the initiator wants us to restart
the data transfer from or to retransmit the response frame.
If the ISP driver still has the CCB around for which the data segment
or response applies, it will retransmit.
However, we typically don't know about a lost data frame until we
send the FCP Response and the initiator totes up counters for data
moved and notices missing segments. In this case we've already
completed the data CCBs already and sent themn back up to the periph
driver. Because there's no really clean mechanism yet in CAM to
handle this, a hack has been put into place to complete the CTIO
CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA
POINTER extended message in it. The internal ISP target groks this
and ctl(8) will be modified to deal with this as well.
At any rate, the data is retransmitted and an an FCP response is
sent. The whole point here is to successfully complete a command
so that you don't have to depend on ULP (SCSI) to have to recover,
which in the case of tape is not really possible (hence the name
FC-TAPE).

-----------
MISC CHANGES
Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee
eventual delivery of a NOTIFY ACK. This is tons better than just
ignoring the return from isp_notify_ack and hoping for the best.
Clean up the lower level lun enable code to be a bit more sensible.
Fix a botch in isp_endcmd which was messing up the sense data.
Fix notify ack for SRR to use a sensible error code in the case
of a reject.
Clean up and make clear what kind of firmware we've loaded and
what capabilities it has.
-----------
FULL (252 byte) SENSE DATA
In CTIOs for the ISP, there's only a limimted amount of space
to load SENSE DATA for associated CHECK CONDITIONS (24 or 26
bytes). This makes it difficult to send full SENSE DATA that can
be up to 252 bytes.
Implement MODE 2 responses which have us build the FCP Response
in system memory which the ISP will put onto the wire directly.
On the initiator side, the same problem occurs in that a command
status response only has a limited amount of space for SENSE DATA.
This data is supplemented by status continuation responses that
the ISP pushes onto the response queue after the status response.
We now pull them all together so that full sense data can be
returned to the periph driver.
This is supported on 23XX, 24XX and 25XX cards.
This is also preparation for doing >16 byte CDBs.
-----------
FC TAPE
Implement full FC-TAPE on both initiator and target mode side. This
capability is driven by firmware loaded, board type, board NVRAM
settings, or hint configuration options to enable or disable. This
is supported for 23XX, 24XX and 25XX cards.
On the initiator side, we pretty much just have to generate a command
reference number for each command we send out. This is FCP-4 compliant
in that we do this per ITL nexus to generate the allowed 1 thru 255
CRN.
In order to support the target side of FC-TAPE, we now pay attention
to more of the PRLI word 3 parameters which will tell us whether
an initiator wants confirmed responses. While we're at it, we'll
pay attention to the initiator view too and report it.
On sending back CTIOs, we will notice whether the initiator wants
confirmed responses and we'll set up flags to do so.
If a response or data frame is lost the initiator sends us an SRR
(Sequence Retransmit Request) ELS which shows up as an SRR notify
and all outstanding CTIOs are nuked with SRR Received status. The
SRR notify contains the offset that the initiator wants us to restart
the data transfer from or to retransmit the response frame.
If the ISP driver still has the CCB around for which the data segment
or response applies, it will retransmit.
However, we typically don't know about a lost data frame until we
send the FCP Response and the initiator totes up counters for data
moved and notices missing segments. In this case we've already
completed the data CCBs already and sent themn back up to the periph
driver. Because there's no really clean mechanism yet in CAM to
handle this, a hack has been put into place to complete the CTIO
CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA
POINTER extended message in it. The internal ISP target groks this
and ctl(8) will be modified to deal with this as well.
At any rate, the data is retransmitted and an an FCP response is
sent. The whole point here is to successfully complete a command
so that you don't have to depend on ULP (SCSI) to have to recover,
which in the case of tape is not really possible (hence the name
FC-TAPE).
