This fixes the long standingproblem about updating NVRAM on Fibre Channel cards and seemsso far to not break SPI config page writes.Put back role setting into mpt. That is, you can set a desired rolefor mpt as a hint. On the next reboot, it'll pick that up and redothe NVRAM settings appropriately and warn you that this won't takeeffect until the next reboot. This saves people the step of havingto find a BIOS utilities disk to set target and/or initiator rolefor the MPT cards.

They seemto be be treated differently for different Fusion implementations.Some will really tell you when it's okay to free the request thatstarted them. Some won't. Very disconcerting.This is particularily bad when the chip (FC in this case) tells youin the reply that it's not a continuation reply, which means youcan free the request that its associated with. However, if you dothat, I've found that additional async event replies come back forthat message context after you freed it. Very Bad Things Happen.Put in a reply register debounce. Warn about out of range contextindices. Use more MPILIB defines where possible. Replace bzero withmemset. Add tons more KASSERTS. Do a *lot* more request free listauditting and serial number usages. Get rid of the warning aboutthe short IOC Facts Reply. Go back to 16 bits of context index.Do a lot more target state auditting as well. Make a tag outof not only the ioindex but the request index as well and worryless about keeping a full serial number.

I'd say thatthis probably works just about as well as isp(4)does right now. Still, it and isp(4) and the wholetarget mode stack need a bit of tightening.B) The startup sequence has been changed so thatafter all attaches are done, a set of enable functionsare called. The idea here is that the attaches dowhatever needs to be done *prior* to a port beingenabled and the enables do what need to be done forenabling stuff for a port after it's been enabled.This means that we also have events handled by theirproper handlers as we start up.C) Conditional code that means that this driver goesback all the way to RELENG_4 in terms of support.D) Quite a lot of little nitty bug fixes- some discoveredby doing RELENG_4 support. We've been living under Giant*waaaayyyyy* too long and it's made some of us (me) sloppy.E) Some shutdown hook stuff that makes sure we don't blowup during a reboot (like by the arrival of a new commandfrom an initiator).There's been some testing and LINT checking, but not ascomplete as would be liked. Regression testing with FusionRAID instances has not been possible. Caveat Emptor.Sponsored by: LSI-Logic.

These controllers (106X) seem to supportautomatically both SATA and SAS drives. The async SAS event handling we catchbut ignore at present (so automagic attach/detach isn't hooked up yet).Do 64 bit PCI support- we can now work on systems with > 4GB of memory.Do large transfer support- we now can support up to reported chain depth, orthe length of our request area. We simply allocate additional request elementswhen we would run out of room for chain lists.Tested on Ultra320, FC and SAS controllers on AMD64 and i386 platforms.There were no RAID cards available for me to regression test.The error recovery for this driver still is pretty bad.

Each module exports load, and unload module scope methods as well as probe, attach, event, reset, shutdown, and detach per-device instance methodsmpt.c mpt.h mpt_pci.c:o The driver now associates a callback function (via an index) with every transaction submitted to the controller. This allows the main interrupt handler to absolve itself of any knowledge of individual transaction/response types by simply calling the callback function "registered" for the transaction. We use a callback index instead of a callback function pointer in each requests so we can properly handle responses (e.g. event notifications) that are not associated with a transaction. Personality modules dynamically register their callbacks with the driver core to receive the callback index to use for their handlers.o Move the interrupt handler into mpt.c. The ISR algorithm is bus transport and OS independent and thus had no reason to be in mpt_pci.c.o Simplify configuration message reply handling by copying reply frame data for the requester and storing completion status in the original request structure.o Add the mpt_complete_request_chain() helper method and use it to implement reset handlers that must abort transactions.o Keep track of all pending requests on the new requests_pending_list in the softc.o Add default handlers to mpt.c to handle generic event notifications and controller reset activities. The event handler code is largely the same as in the original driver. The reset handler is new and terminates any pending transactions with a status code indicating the controller needs to be re-initialized.o Add some endian support to the driver. A complete audit is still required for this driver to have any hope of operating in a big-endian environment.o Use inttypes.h and __inline. Come closer to being style(9) compliant.o Remove extraneous use of typedefs.o Convert request state from a strict enumeration to a series of flags. This allows us to, for example, tag transactions that have timed-out while retaining the state that the transaction is still in-flight on the controller.o Add mpt_wait_req() which allows a caller to poll or sleep for the completion of a request. Use this to simplify and factor code out from many initialization routines. We also use this to sleep for task management request completions in our CAM timeout handler.mpt.c:o Correct a bug in the event handler where request structures were freed even if the request reply was marked as a continuation reply. Continuation replies indicate that the controller still owns the request and freeing these replies prematurely corrupted controller state.o Implement firmware upload and download. On controllers that do not have dedicated NVRAM (as in the Sun v20/v40z), the firmware image is downloaded to the controller by the system BIOS. This image occupies precious controller RAM space until the host driver fetches the image, reducing the number of concurrent I/Os the controller can processes. The uploaded image is used to re-program the controller during hard reset events since the controller cannot fetch the firmware on its own. Implementing this feature allows much higher queue depths when RAID volumes are configured.o Changed configuration page accessors to allow threads to sleep rather than busy wait for completion.o Removed hard coded data transfer sizes from configuration page routines so that RAID configuration page processing is possible.mpt_reg.h:o Move controller register definitions into a separate file.mpt.h:o Re-arrange includes to allow inlined functions to be defined in mpt.h.o Add reply, event, and reset handler definitions.o Add softc fields for handling timeout and controller reset recovery.mpt_cam.c:o Move mpt_freebsd.c to mpt_cam.c. Move all core functionality, such as event handling, into mpt.c leaving only CAM SCSI support here.o Revamp completion handler to provide correct CAM status for all currently defined SCSI MPI message result codes.o Register event and reset handlers with the MPT core. Modify the event handler to notify CAM of bus reset events. The controller reset handler will abort any transactions that have timed out. All other pending CAM transactions are correctly aborted by the core driver's reset handler.o Allocate a single request up front to perform task management operations. This guarantees that we can always perform a TMF operation even when the controller is saturated with other operations. The single request also serves as a perfect mechanism of guaranteeing that only a single TMF is in flight at a time - something that is required according to the MPT Fusion documentation.o Add a helper function for issuing task management requests to the controller. This is used to abort individual requests or perform a bus reset.o Modify the CAM XPT_BUS_RESET ccb handler to wait for and properly handle the status of the bus reset task management frame used to reset the bus. The previous code assumed that the reset request would always succeed.o Add timeout recovery support. When a timeout occurs, the timed-out request is added to a queue to be processed by our recovery thread and the thread is woken up. The recovery thread processes timed-out command serially, attempting first to abort them and then falling back to a bus reset if an abort fails.o Add calls to mpt_reset() to reset the controller if any handshake command, bus reset attempt or abort attempt fails due to a timeout.o Export a secondary "bus" to CAM that exposes all volume drive members as pass-thru devices, allowing CAM to perform proper speed negotiation to hidden devices.o Add a CAM async event handler tracking the AC_FOUND_DEVICE event. Use this to trigger calls to set the per-volume queue depth once the volume is fully registered with CAM. This is required to avoid hitting firmware limits on volume queue depth. Exceeding the limit causes the firmware to hang.mpt_cam.h:o Add several helper functions for interfacing to CAM and performing timeout recovery.mpt_pci.c:o Disable interrupts on the controller before registering and enabling interrupt delivery to the OS. Otherwise we risk receiving interrupts before the driver is ready to receive them.o Make use of compatibility macros that allow the driver to be compiled under 4.x and 5.x.mpt_raid.c:o Add a per-controller instance RAID thread to perform settings changes and query status (minimizes CPU busy wait loops).o Use a shutdown handler to disable "Member Write Cache Enable" (MWCE) setting for RAID arrays set to enable MWCE During Rebuild.o Change reply handler function signature to allow handlers to defer the deletion of reply frames. Use this to allow the event reply handler to queue up events that need to be acked if no resources are available to immediately ack an event. Queued events are processed in mpt_free_request() where resources are freed. This avoids a panic on resource shortage.o Parse and print out RAID controller capabilities during driver probe.o Define, allocate, and maintain RAID data structures for volumes, hidden member physical disks and spare disks.o Add dynamic sysctls for per-instance setting of the log level, array resync rate, array member cache enable, and volume queue depth.mpt_debug.c:o Add mpt_lprt and mpt_lprtc for printing diagnostics conditioned on a particular log level to aid in tracking down driver issues.o Add mpt_decode_value() which parses the bits in an integer value based on a parsing table (mask, value, name string, tuples).mpilib/*:o Update mpi library header files to latest distribution from LSI.Submitted by: gibbsApproved by: re List of files: /freebsd-13.1/sys/dev/mpt/mpt_debug.c Sun, 10 Jul 2005 15:05:39 +0000 Scott Long <scottl@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/sys/dev/mpt/mpt_debug.c#098ca2bd Start each of the license/copyright comments with /*-, minor shuffle of lines List of files: /freebsd-13.1/sys/dev/mpt/mpt_debug.c Thu, 06 Jan 2005 01:43:34 +0000 Warner Losh <imp@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/sys/dev/mpt/mpt_debug.c#9295c6c5 Fix where my automated script blew the SCM ID format conversion.
