763fae7918 ntroduce mfiutil, a basic utility for managing LSI SAS-RAID & Dell PERC5/6
controllers.  Controller, array, and drive status can be checked, basic
attributes can be changed, and arrays and spares can be created and deleted.
Controller firmware can also be flashed.

This does not replace MegaCLI, found in ports, as that is officially sanctioned
and supported by LSI and includes vastly more functionality.  However, mfiutil
is open source and guaranteed to provide basic functionality, which can be
especially useful if you have a problem and can't get MegaCLI to work.

444b91868b Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.

Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.

For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.

Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.

Bump __FreeBSD_version in order to reflect the newbus lock introduction.

52c9ce25d8 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.

2137b017d7 Tweak the output of event log messages from the controller:
- Each log entry contains a text description in the "description" field of
  the entry.  The existing decode logic always ended up duplicating
  information that was already in the description string.  This made the
  logs overly verbose.  Now we just print out the description string.
- Add some simple parsing of the timestamp and event classes.

c1ed06a84b Adjust the handling of pending log events during boot:
- Fetch events from the controller in batches of 15 rather than a single
  event at a time.
- When fetching events from the controller, honor the event class and
  locale settings (via hw.mfi tunables).  This also allows the firmware to
  skip over unwanted log entries resulting in fewer requests to the
  controller if there many unwanted log entries since the last clean
  shutdown.
- Don't drop the driver mutex while decoding an event.
- If we get an error other than MFI_STAT_NOT_FOUND (basically EOF for
  hitting the end of the event log) then emit a warning and bail on
  processing further log entries.

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.

5be25877a1 Add in a couple of things:
-	In the ioctl path let command get queued up and return
	when complete _without_ blocking the driving waiting for
	the response.  This way the driver doesn't "lock up" for
	~30s during a flash command.  Submitted by scottl.
      -	Add a guard so that if a DCMD of 0 is sent down the ioctl
	path don't send it to the controller.  Return with a
	status of OK.  This is a little strange since MegaCli
	doesn't seem to like something and will issue some DCMD
	of 0.  This doesn't happen under Linux.  So the emulation
	needs to be improved but I'm not sure what.  Another strange
	thing is that when a DCMD of 0 gets issued under i386 the
	controller returns OK but in amd64 the context is messed
	up.
      -	Add a guard so the context has to be with-in the legal
	limit so we get a reasonable error assertion versus random
	panic.

It's going to be a challenge to figure out why MegaCli is not totally
happy and then sends some bogus commands.  This means that flashing
firmware via the Linux tool won't work since it generates a DCMD of
0 when it should be opening the firmware for a flash update.  Without
this problem flashing works fine.  This means there is no publicly
available tool to upgrade the RAID firmware under FreeBSD right now.

I plan to MFC all of the mfi changes to 6.X shortly.  This might not
include the SCSI pass-through changes.

812819c7b1 Some relatively minor changes and bug fixes:
1)	s/mi/mfi/ in FreeBSD ioctl path
     2)	add in "\n" on various failure messages
     3)	cap the length of time to abort an AEN command
     4)	fix passing sense data back to user to make Dell's Linux firmware
	upgrade tool happy.
     5)	bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the
	firmware flash command can take ~40s to return.

This is some clean-up and enables RAID firmware to updated via Dell's
tool.  Note Dell's tool requires the updates to the Linux emulator
that has been done in -current with TLS etc.

I need to discuss with scottl how to better submit mfi commands to

getting posted twice to the driver.  This is turn fixes panics on shutdown
when INVARIANTS is set.
