Make MAXPHYS tunable. Bump MAXPHYS to 1M. Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work. Changes to cam/, dev/ahci, dev/ata, dev/mpr, dev/mpt, dev/mvs, dev/siis, where either submitted by, or based on changes by mav.

sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Prevent overflow issues in timeout processing Previously, any timeout value for which (timeout * hz) will overflow the signed integer, will give weird results, since callout(9) routines will convert negative values of ticks to '1'. For unsigned integer overflow we will get sufficiently smaller timeout values than expected. Switch from callout_reset, which requires conversion to int based ticks to callout_reset_sbt to avoid this. Also correct isci to correctly resolve ccb timeout. This was based on the original work done by Eygene Ryabinkin <rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid the overlow.

Change the mpt driver to allow larger I/O sizes. The mpt driver previously didn't report a 'maxio' size to CAM, and so the da(4) driver limited I/O sizes to DFLTPHYS (64K) by default. The number of scatter gather segments allowed, as reported to busdma, was (128K / PAGE_SIZE) + 1, or 33 on architectures with 4K pages. Change things around so that we wait until we've determined how many segments the adapter can support before creating the busdma tag used for buffers, so we can potentially support more S/G segments and therefore larger I/O sizes. Also, fix some things that were broken about the module unload path. It still gets hung up inside CAM, though. mpt.c: Move some busdma initialization calls in here, and call them just after we've gotten the IOCFacts, and know how many S/G segments this adapter can support. mpt.h: Get rid of MPT_MAXPHYS, it is no longer used. Add max_cam_seg_cnt, which is used to report our maximum I/O size up to CAM. mpt_cam.c: Use max_cam_seg_cnt to report our maximum I/O size to CAM. Fix the locking in mpt_cam_detach(). mpt_pci.c: Pull some busdma initialization and teardown out and put it in mpt.c. We now delay it until we know many scatter gather segments the adapter can support, and therefore how to setup our busdma tags. mpt_raid.c: Make sure we wake up the right wait channel to get the raid thread to wake up when we're trying to shut it down.

Separate the parallel scsi knowledge out of the core of the XPT, and modularize it so that new transports can be created. Add a transport for SATA Add a periph+protocol layer for ATA Add a driver for AHCI-compliant hardware. Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS. The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers. ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available. This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options. Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies. The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged. Submitted by: scottl, mav Approved by: re

Make the whole initiator mode part of mpt(4) endian-clean, specifically SPI controllers now also work in big-endian machines and some conversions relevant for FC and SAS controllers as well as support for ILP32 machines which all were omitted in previous attempts are now also implemented. The IOCTL-interface is intentionally left (and where needed actually changed) to be completely little-endian as otherwise we would have to add conversion code for every possible configuration page to mpt(4), which didn't seem the right thing to do, neither did converting only half of the user- interface to the native byte order. This change was tested on amd64 (SAS+SPI), i386 (SAS) and sparc64 (SAS+SPI). Due to lack of the necessary hardware the target mode code is still left to be made endian-clean.

mpt.c: mpt.h: Add support for reading extended configuration pages. mpt_cam.c: Do a top level topology scan on the SAS controller. If any SATA device are discovered in this scan, send a passthrough FIS to set the write cache. This is controllable through the following tunable at boot: hw.mpt.enable_sata_wc: -1 = Do not configure, use the controller default 0 = Disable the write cache 1 = Enable the write cache The default is -1. This tunable is just a hack and may be deprecated in the future. Turning on the write cache alleviates the write performance problems with SATA that many people have observed. It is not recommend for those who value data reliability! I cannot stress this strongly enough. However, it is useful in certain circumstances, and it brings the performence in line with what a generic SATA controller running under the FreeBSD ATA driver provides (and the ATA driver has had the WC enabled by default for years).

Fix config page writes to not strip out the attributes when you actually go write the config page. This fixes the long standing problem about updating NVRAM on Fibre Channel cards and seems so far to not break SPI config page writes. Put back role setting into mpt. That is, you can set a desired role for mpt as a hint. On the next reboot, it'll pick that up and redo the NVRAM settings appropriately and warn you that this won't take effect until the next reboot. This saves people the step of having to find a BIOS utilities disk to set target and/or initiator role for the MPT cards.

Use the PIM_SEQSCAN flag for U320- this seems to correct cases of being unable to consistently negotiate U320 in the cases where I'd seen this before. Between this and other recent checkins, this driver is pretty close to being ready for MFC. Reviewed by: scottl, ken, scsi@ MFC after: 1 week

Work in progress toward fixing IM checked in after having lost one set to a peninsula power failure last night. After this, I can see both submembers and the raid volumes again, but speed negotiation is still broken. Add a mpt_raid_free_mem function to centralize the resource reclaim and fixed a small memory leak. Remove restriction on number of targets for systems with IM enabled- you can have setups that have both IM volumes as well as other devices. Fix target id selection for passthru and nonpastrhu cases. Move complete command dumpt to MPT_PRT_DEBUG1 level so that just setting debug level gets mostly informative albeit less verbose dumping.

A large set of changes: + Add boatloads of KASSERTs and *really* check out more locking issues (to catch recursions when we actually go to real locking in CAM soon). The KASSERTs also caught lots of other issues like using commands that were put back on free lists, etc. + Target mode: role setting is derived directly from port capabilities. There is no need to set a role any more. Some target mode resources are allocated early on (ELS), but target command buffer allocation is deferred until the first lun enable. + Fix some breakages I introduced with target mode in that some commands are *repeating* commands. That is, the reply shows up but the command isn't really done (we don't free it). We still need to take it off the pending list because when we resubmit it, bad things then happen. + Fix more of the way that timed out commands and bus reset is done. The actual TMF response code was being ignored. + For SPI, honor BIOS settings. This doesn't quite fix the problems we've seen where we can't seem to (re)negotiate U320 on all drives but avoids it instead by letting us honor the BIOS settings. I'm sure this is not quite right and will have to change again soon.

Fix some of the previus changes 'better'. There's something strange going on with async events. They seem to be be treated differently for different Fusion implementations. Some will really tell you when it's okay to free the request that started them. Some won't. Very disconcerting. This is particularily bad when the chip (FC in this case) tells you in the reply that it's not a continuation reply, which means you can free the request that its associated with. However, if you do that, I've found that additional async event replies come back for that message context after you freed it. Very Bad Things Happen. Put in a reply register debounce. Warn about out of range context indices. Use more MPILIB defines where possible. Replace bzero with memset. Add tons more KASSERTS. Do a *lot* more request free list auditting and serial number usages. Get rid of the warning about the short IOC Facts Reply. Go back to 16 bits of context index. Do a lot more target state auditting as well. Make a tag out of not only the ioindex but the request index as well and worry less about keeping a full serial number.

Some fairly major changes to this driver. A) Fibre Channel Target Mode support mostly works (SAS/SPI won't be too far behind). I'd say that this probably works just about as well as isp(4) does right now. Still, it and isp(4) and the whole target mode stack need a bit of tightening. B) The startup sequence has been changed so that after all attaches are done, a set of enable functions are called. The idea here is that the attaches do whatever needs to be done *prior* to a port being enabled and the enables do what need to be done for enabling stuff for a port after it's been enabled. This means that we also have events handled by their proper handlers as we start up. C) Conditional code that means that this driver goes back all the way to RELENG_4 in terms of support. D) Quite a lot of little nitty bug fixes- some discovered by 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 blow up during a reboot (like by the arrival of a new command from an initiator). There's been some testing and LINT checking, but not as complete as would be liked. Regression testing with Fusion RAID instances has not been possible. Caveat Emptor. Sponsored by: LSI-Logic.

Do initial cut of SAS HBA support. These controllers (106X) seem to support automatically both SATA and SAS drives. The async SAS event handling we catch but 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, or the length of our request area. We simply allocate additional request elements when 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.

Massive overhaul of MPT Fusion driver: o Add timeout error recovery (from a thread context to avoid the deferral of other critical interrupts). o Properly recover commands across controller reset events. o Update the driver to handle events and status codes that have been added to the MPI spec since the driver was originally written. o Make the driver more modular to improve maintainability and support dynamic "personality" registration (e.g. SCSI Initiator, RAID, SAS, FC, etc). o Shorten and simplify the common I/O path to improve driver performance. o Add RAID volume and RAID member state/settings reporting. o Add periodic volume resynchronization status reporting. o Add support for sysctl tunable resync rate, member write cache enable, and volume transaction queue depth. Sponsored by ---------------- Avid Technologies Inc: SCSI error recovery, driver re-organization, update of MPI library headers, portions of dynamic personality registration, and misc bug fixes. Wheel Open Technologies: RAID event notification, RAID member pass-thru support, firmware upload/download support, enhanced RAID resync speed, portions of dynamic personality registration, and misc bug fixes. Detailed Changes ================ mpt.c mpt_cam.c mpt_raid.c mpt_pci.c: o Add support for personality modules. Each module exports load, and unload module scope methods as well as probe, attach, event, reset, shutdown, and detach per-device instance methods mpt.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.

Add support for the LSI-Logic Fusion/MP architecture. This is an architecture that present a thing message passing interface to the OS. You can query as to how many ports and what kind are attached and enable them and so on. A less grand view is that this is just another way to package SCSI (SPI or FC) and FC-IP into a one-driver interface set. This driver support the following hardware: LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only) LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only) LSI 53c1020: Single Channel, Ultra4 (320M) (Untested) LSI 53c1030: Dual Channel, Ultra4 (320M) Currently it's in fair shape, but expect a lot of changes over the next few weeks as it stabilizes. Credits: The driver is mostly from some folks from Jeff Roberson's company- I've been slowly migrating it to broader support that I it came to me as. The hardware used in developing support came from: FC909: LSI-Logic, Advansys (now Connetix) FC929: LSI-Logic 53c1030: Antares Microsystems (they make a very fine board!) MFC after: 3 weeks
