Add a bustype_async_event_xfer_mode() callback to scsipi_bustype (which can be NULL), so that transport-specific details of transfer mode setting/printing can be handled more easily. Move scsipi_async_event_xfer_mode() and scsipi_print_xfer_mode() to scsi_base.c and split in parallel scsi and FC/SAS parts. size of struct scsipi_bustype has changed, welcome to 6.99.5

Expand struct scsipi_bustype {} in a ABI-backward-compatible way to
pass more informations about the bus:
- bustype_type has 2 different bytes, one holding the existing
SCSIPI_BUSTYPE_* (scsi, atapi, ata), and one for a per-SCSIPI_BUSTYPE_*
subtype. Introduce macros to build or extract bustype_type.
- for SCSIPI_BUSTYPE_SCSI, define subtypes for parallel SCSI, Fibre Channel,
SAS and USB, to specify the transport method. SCSIPI_BUSTYPE_SCSI_PSCSI
is 0 so that bustype_type value doesn't change for existing code
- for non-SCSIPI_BUSTYPE_SCSI busses there's no defined subtype yet,
so the bustype_type value doesn't change.
- provide scsi_fc_bustype, scsi_sas_bustype and scsi_usb_bustype
along with scsi_bustype to be used by bus driver where appropriate
- scsipi_print_xfer_mode(): more existing code under a
(SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_PSCSI) case, as
sync/wide parameters only make sense for parallel SCSI.
For (SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_FC) and
(SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_SAS), only print
tagged queing status if enabled. Just be silent for other
bustypes.
This change is prompted by this problem:
right now, FC (e.g. isp(4)) and SAS (e.g. mfi(4)) don't
do anything for ADAPTER_REQ_SET_XFER_MODE, and especially never
call scsipi_async_event(ASYNC_EVENT_XFER_MODE), so sd(4) always
runs untagged. Doing a scsipi_async_event(ASYNC_EVENT_XFER_MODE) with
appropriate parameters is enough to enable tagged queuing,
but then scsipi will print:
sd0: async, 8-bit transfers, tagged queueing
which is harmless (async, 8-bit transfers doens't make sense on SAS anyway)
but will confuse users. With this change scsipi will only print:
sd0: tagged queueing
which is correct.
In the long run, knowning the underlying transport in scsipi will
allow better handling of device which are not parallel SCSI.
Another change adding an extra callback to struct scsipi_bustype {}
will come (so that scsipi_print_xfer_mode(), which is SCSI-specific,
can be moved out of scsipi_base, and split into per-subtype callback),
but this will break kernel ABI and so is not suitable for
netbsd-6, so will be commmited later. The above is enough to get
tagged queuing on FC and SAS in netbsd-6.

Convert one second(!!) delay to kpause. It was originally done from a callout, so delay was the only option (in those days). Then the caller was converted to a thread, but left as a delay. It still may block the scsipi completion thread processing (so I seriously doubt this code path is executed very often on a live system).

Extract SCSIVERBOSE into a kernel module. The module can be builtin by defining 'options SCSIVERBOSE' in the kernel config file (no change from current behavior), or it can be loaded at boot time on those architectures that support the boot loader's "load" command. The module is built for all architectures, whether or not SCSI or atapi support exists.

Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.

If the block size reported by Read Capacity looks valid, just use it. Use Request Sense only if Read Capacity succeeded and did not return valid block size. Discussed on tech-kern. Fix the easier part of NetBSD PR kern/26537. (The harder part is the device hangs on large (>= 8KB) transfer. Possibly umass BBB problem?) Remove scsipi_size() and scsipi_validate_secsize() from scsipi_base.c and add their functions to sd.c since they are used only by sd.c. Use SCSI term `block' instead of `sector' where applicable.

Some removable umass(4) devices don't respond to mode sense page 6, or simply return zero for logical block size. In either case, use the sector length reported by READ_CAPACITY instead of defaulting to 512 bytes. This partially addresses the problems reported in PR port-i386/34707 and PR kern/34737. Namely the incorrectly reported drive geometry and the 'hanging' issue. However, since the device in question reports 2048-byte physical sectors it will remain unusable until DEV_BSIZE is banished.

Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name everything "scsi_*", since we really are talking about the SCSI command set, ATAPI transport not withstanding. Improve the names of many structures, and prepend "SCSI_" onto all SCSI command opcodes. Place items described by the SCSI Primary Commands document into scsi_spc.h.

Part of the cleanup of sys/scsipi's use of types; rename all u_int* to uint* and change the u_long's to uint32_t's where possible. Note that the iocl definitions/hooks have to be ulong (or u_long) or they'll bomb out.

And thus spake SBC-3: If the number of logical blocks exceeds the maximum value that is able to be specified in the RETURNED LOGICAL BLOCK ADDRESS field, the device server shall set the RETURNED LOGICAL BLOCK ADDRESS field to FFFFFFFFh. The application client should then issue a READ CAPACITY (16) command (see 5.11) to retrieve the READ CAPACITY (16) parameter data. Implement this in scsipi_size(). First issue in kern/28514.

If our enqueue failed -- because we're polling and there is already something in the queue -- do not attempt to requeue it. We only poll in two cases: 1) We have a non-interrupting controller. In this case, execution of the previous command should have left the queue empty. (Perhaps there should be a KASSERT() to this effect.) 2) We're in the shutdown path, either doing a cache sync or a dump. In these cases, the retry behavior is useless, because we will no longer get interrupts to notify us that the earlier commands completed. Instead we just spin for a few seconds and fail anyway. (XXX We should probably clear the queue explicitly so that the shutdown/dump will succeed.)

Make bustype_cmd and PHOLD/PRELE be called from scsipi_execute_xs(). This allows us to create a xfer structure -- possibly on the stack -- and call scsipi_execute_xs() directly.

Make the xxstart() functions reentrant again, as some drivers HBA can call scsipi_done() from their scsipi_request(). For this, add a struct scsipi_xfer * argument to scsipi_command(). If not NULL scsipi_command() will use this to enqueue this xfer, otherwise it'll try to allocate a new one. This scsipi_xfer has to be allocated and initialised by scsipi_make_xs() or equivalent. In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL, dequeue the buffer before calling scsipi_command(). This makes sure that scsipi_command() will not fail, and also makes sure that xxstart() won't be called again between the BUFQ_PEEK() and BUFQ_GET(). Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in private mail and Andreas Wrede on current-users@. Thanks to Jason Thorpe and Chuck Silver for review, and Andreas Wrede for testing the patch.

Improve handling of memory shortage, to fix problems like: sd3(mpt0:0:1:0): unable to allocate scsipi_xfer sd3: not queued, error 12 Havard Eidnes's analysis of this problem is that the scsipi_xfer pool is competing for resources with other pools, including the the inode and vnode pools which can grow quite large. *_scsipi_cmd(): don't biodone the buffer if scsipi_make_xs() fails, let the caller deal with the problem start function of block devices drivers: dequeue the buffer after the scsipi_command() call. If scsipi_command() fails with ENOMEM don't dequeue the buffer, and schedule a callout to call the start function after some delay. scsipi_init(): prime the scsipi_xfer_pool with one page. This ensure that there is always some scsipi_xfer to play with. If scsipi_command() fails because of pool_get(), we're sure there will be resources available later, when the pending commands have completed. Reviewed by Jason Thorpe and Havard Eidnes. Todo: remove the "unable to allocate scsipi_xfer" and "not queued, error %d" printfs, but I choose to keep them for now, to help make sure the code does what it should.

Fix some problems in the scsipi detach code: - only call periph_switch->psw_start() if the device is active; if it is not psw_start() may try to access invalid data. - remove the TAILQ_FIRST(&periph->periph_xferq) != NULL diagnostic in scsipi_kill_pending(). This can't be true at this point (unless the device was idle at the time of the detach), because the scsipi channel kernel thread has to run for the queue to be flushed. There are still other problems to be fixed here ...

Revert part of 1.102: Don't decrease/check xs_retries when the device report "Power On, Reset, or Bus Device Reset" sense condition, just retry the command. The initial bus reset would cause the first TEST_UNIT_READY to report this condition, and as xs_retries is set to 0 when XS_CTL_DISCOVERY is set, it would report an error instead of being retried, causing the disk probe to report "drive offline" instead of the geometry and capacity. Checking/decreasing xs_retries on the bus reset reported by the adapter is enouth to avoid the problem reported by rev 1.102. Problem analysed by Paul Kranenburg, fix confirmed by Anders Hjalmars, and explaination as to why the INQUIRY wasn't affected by this provided by Bill Studenmund.

Force the initial probes to happen within the newly forked off kthread. This eliminates problems where the underlying interrupt handler isn't the specific layer calling scsipi_complete() for a given scsi transaction. This avoids deadlocks where the kthread that called the autoconf routines to configure a scsibus shouldn't be the one put to sleep waiting on a scsipi_complete (only the scsibus's kthread should be doing that). To avoid jitter this will force the scsibus's to probe in the order they run through autoconf (so machines with multiple bus's don't move sd* devices around on every reboot).

Present the same interface to periph driver for ASYNC scsipi_command() in the normal case, and in the polling or "no thread yet" cases: don't return an error from scsipi_complete(), as the error should already have been handled in scsipi_complete() and eventually periph driver callbacks. Should fix kern/15190.

Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

Rather than run a periph's queue from scsipi_periph_timed_thaw which is called via a callout, kick the completion thread to run it for us (uses a new flag, SCSIPI_CHAN_KICK). If we've received BUSY status and we haven't started the completion thread yet, don't freeze do a callout to scsipi_periph_timed_thaw which then will try and kick the completion thread- instead treat the command as if it were a polled command and just call delay for 1 second. If DIAGNOSTIC is defined, and the periph qfreeze count is less than zero, panic because some HBA has corrupted the periph structure's accounting.

Workaround for broken drives (explained to me by Chris G. Demetriou): some devices can't handle tag number larger than some values and always reject commands with QUEUE FULL if the tag number is larger than this. Under some circonstances the scsipi system may not decrease periph_openings (as a workaround of other odd behavior) and we may end up requeuing the command with a hight tag value again, and the driver could loop on this. Workaround: in case of queue full, decrease periph_openings to min(periph_active - 1, periph_openings - 1) so that, after some iteration, periph_openings is less than the max tag value acceptable by the device. Solves the problem with tagged queuing on ncr53c9x for me.

Pull up the thorpej_scsipi branch to main branch. This is a completely rewritten scsipi_xfer execution engine, and the associated changes to HBA drivers. Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate. Just before the merge syssrc has been tagged with thorpej_scsipi_beforemerge

- When allocating a scsipi_xfer, add it to the specified device's pending_xfers queue. - When freeing a scsipi_xfer, remove it from the device's pending_xfers queue. If the queue is empty, and SDEV_WAITDRAIN is set, wakeup those waiting for the queue to drain. - Implement scsipi_wait_drain(), which waits for a device's pending_xfers queue to drain.

Add support for reference counting and enabling/disabling SCSI and ATAPI controllers. This will eventually be used for power management of e.g. PCMCIA SCSI and IDE controller cards.

Rename scsi_interpret_sense() to scsipi_interpret_sense() and move it from scsi_base.c to scsipi_base.c. Rename the functions from scsi_verbose.c too, and rename the file itself. Cleaup includes too (scsi_*.h should not be #included in scsipi_*.h files, which are supposed to be common to atapi and scsi).

SCSI_ASYNCREQ turns out to be redundant; we can simply free the scsipi_xfer in scsipi_done() if the transfer is asynchronous. This reduces the size of the critical section in scsipi_execute_xs() somewhat (in fact, back to its original size).

Found a race in scsipi_execute_xs(): if an asynchronous transfer completes (probably due to an interrupt) between the time it is scheduled and the time we get around to setting the SCSI_ASYNCREQ flag, we can lose the xs. Fix this by checking to see if the transfer has already completed after the scsi_cmd function returns SUCCESSFULLY_QUEUED, and just return to the caller if so.

Fix a problem uncovered when we started to use the pool allocator to manage scsipi_xfer structures. When scsipi_execute_xs() calls the driver's scsi_cmd function, it assumes that it can still dereference a pointer to the scsipi_xfer struct. Since scsipi_done() has already been called, which in turn has called scsipi_free_xs(), the struct has already been returned to the pool! In other words, xs->flags has been compromised, but we are still testing it. These changes resolve the problem by doing the following: - In scsipi_execute_xs(), if the lower-level driver's scsi_cmd function returns SUCCESSFULLY_QUEUED and SCSI_NOSLEEP is set in xs->flags, set a new flag (SCSI_ASYNCREQ). This indicates that scsipi_done() should free the scsipi_xfer struct. If the lower-level driver's scsi_cmd function returns SUCCESSFULLY_QUEUED but SCSI_NOSLEEP is not set, we wait (via tsleep()) for the request to complete, then fall through to the COMPLETE case. If the lower-level driver's scsi_cmd function returns COMPLETE, we now simply return any actual errors, or 0 if none occurred. (Previously, we may have returned EJUSTRETURN, of which the sole effect was to avoid freeing the scsipi_xfer struct in our caller. No code seems to depend on this behavior, however.) - In scsipi_done(), only free the scsipi_xfer struct for async requests. The contents of the struct will otherwise remain valid until the function that initiated the transfer frees it. With this change, responsibility for freeing the struct now lies in two places, depending on the type of the request: - For synchronous requests, the routine calling scsipi_execute_xs() must clean up. - For asynchronous requests, scsipi_done() cleans up (as it always has). [Note: this change also corrects a problem with sddump(): scsipi_done() was attempting to return a static scsipi_xfer struct to the pool! Since dumps are performed synchronously, we now handle this correctly.] This solution was provided by Jason Thorpe, after I got him to look at some related (but insufficient) attempts of my own.
