847bd80810 Allocate a single CCB at the start of the main loop of the RAID monitoring
kthread of the mpt(4) driver that hangs around for the entire lifetime of
the thread.  Previously the driver would allocate a new CCB using M_WAITOK
with a lock held each time it updated its state.  While here, use the
CAM API for allocating a CCB rather than raw malloc(9).

4124f62e4f Rework how the mpt_user personality handles buffers for config pages.
Previously we reused the space in the request buffer after the request
header to hold config pages during a transaction.  This does not work when
reading large pages however.  Also, we were already malloc'ing a buffer to
do a copyin/copyout w/o holding locks that was then copied into/out of the
request buffer.  Instead, go ahead and use bus dma to alloc a buffer for
each config page request (and RAID actions that have an associated
ActionSGE).  This results in fewer data copies and allows for larger sized
requests.  For now the maximum size of a request is arbitrarily limited to
16 MB.

ee98c4a50e Add a new personality to mpt(4) devices to allow userland applications to
perform various operations on a controller.  Specifically, for each mpt(4)
device, create a character device in devfs which accepts ioctl requests for
reading and writing configuration pages and performing RAID actions.

e955d4fd10 The MPT driver treats the "core" module with the same importance and
abstraction as the RAID and CAM modules, making it nearly impossible
for enough initialization to be done in time for the RAID module to
know whether to attach.  On top of this, no reset was being done on
the controller on attach, in violation of the spec.  Additionally,
the port enable step was being deferred to the end of the attach
process, long after it should have been done to ensure reliable
operation from the controller.  Fix all of these with a few hacks
to force the "attach" and "enable" steps of the core module early
on, and ensure that a reset and port enable also happens early on.
In the future, the driver needs to be refactored to eliminate the
core module abstraction, clean up withe reset/enable steps, and
defer event messages until all of the modules are available to
recieve them.

fee67c1a14 Ever since the module registration system was introduced to this driver,
it's been printing out scary messages about "Unhanded Event Notify Frame"
that are needlessly worrisome to users.  Change this warning to only print
out at an elevated debugging level.

3745c395ec Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.

b50569b71d Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

1d558d6a15 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).

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

c5da377e0e Fix a massive couple of botches here: the NVRAM settings
read wasn't flagging the SYNC mode was enabled. The temp
values for offset and sync period were uint8_t, but were
being assigned and shifted from a uint32_t value.

This didn't show up in testing because a random number
of 1030 cards set a bit that says "honor BIOS negotiation",
which means this whole code path was skipped.

This should clear up at least some of the negotation
issues that have been seen.
