yamt | - change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)

reinoud | Backing out changes to clean up scsipi. I was pointed out there were
problems i hadn't seen. To prevent lossage i'd decided to back off all
changes and let them be reviewed on tech-kern.

reinoud | 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.

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.

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.

bouyer | branches: 1.3.2;
Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
Main changes to the scsipi code itself:
- add a scsipi_channel->type to allow umass to attach to both atapibus and
scsibus. Will die when IDE is converted from ata_atapi_attach to
scsipi_channel/scsipi_adapter
- Add a chan_defquirks to scsipi_channel so that adapters can pass a default
set of quirks to be set for each device attached
- add adapt_getgeom and adapt_accesschk callbacks

There is a lot more work to do, but this correctly functions for the most
part on several file servers I run.

he | Pull up revision 1.12 (via patch, requested by bouyer in ticket #837):
Improve handling of memory shortage, to fix problems like:
sd3(mpt0:0:1:0): unable to allocate scsipi_xfer
sd3: not queued, error 12
The theory is that other consumers of pool memory is causing
this memory shortage in certain somewhat hard to reproduce
situations.
This is done by giving scsipi_command an extra argument to
optionally pass a preallocated scsipi_xfer, and allocating a
scsipi_xfer before dequeueing a buffer in the various *start()
functions. If the allocation of a scsipi_xfer fails, schedule
a callout for delayed invocation of the start function. Also
reserve one page for scsipi_xfer structs, to ensure that we will
eventually have some available once pending commands complete.
Should fix PR#25670.
