a6ba0fd64d MFhead_mfi r227068
First cut of new HW support from LSI and merge into FreeBSD.
	Supports Drake Skinny and ThunderBolt cards.
MFhead_mfi r227574
	Style
MFhead_mfi r227579
	Use bus_addr_t instead of uintXX_t.
MFhead_mfi r227580
	MSI support
MFhead_mfi r227612
	More bus_addr_t and remove "#ifdef __amd64__".
MFhead_mfi r227905
	Improved timeout support from Scott.
MFhead_mfi r228108
	Make file.
MFhead_mfi r228208
	Fixed botched merge of Skinny support and enhanced handling
	in call back routine.
MFhead_mfi r228279
	Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH().
MFhead_mfi r228310
	Move mfi_decode_evt() to taskqueue.
MFhead_mfi r228320
	Implement MFI_DEBUG for 64bit S/G lists.
MFhead_mfi r231988
	Restore structure layout by reverting the array header to
	use [0] instead of [1].
MFhead_mfi r232412
	Put wildcard pattern later in the match table.
MFhead_mfi r232413
	Use lower case for hexadecimal numbers to match surrounding
	style.
MFhead_mfi r232414
	Add more Thunderbolt variants.
MFhead_mfi r232888
	Don't act on events prior to boot or when shutting down.
	Add hw.mfi.detect_jbod_change to enable or disable acting
	on JBOD type of disks being added on insert and removed on
	removing.  Switch hw.mfi.msi to 1 by default since it works
	better on newer cards.
MFhead_mfi r233016
	Release driver lock before taking Giant when deleting children.
	Use TAILQ_FOREACH_SAFE when items can be deleted.  Make code a
	little simplier to follow.  Fix a couple more style issues.
MFhead_mfi r233620
	Update mfi_spare/mfi_array with the actual number of elements
	for array_ref and pd.  Change these max. #define names to avoid
	name space collisions.  This will require an update to mfiutil
	It avoids mfiutil having to do a magic calculation.

	Add a note and #define to state that a "SYSTEM" disk is really
	what the firmware calls a "JBOD" drive.

Thanks to the many that helped, LSI for the initial code drop,
mav, delphij, jhb, sbruno that all helped with code and testing.

0d9a4ef39c First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards.
Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI
cards.

Initial code was supplied by LSI under BSD license.  Several improvements
were done by myself.  Such things like making it work in a static kernel,
be able to boot of the RAID, performance improvements.  I removed some
fairly complicated code that seemed to directly access the disks under
the firmware.  It doesn't seem to be needed and significantly slowed
down the performance of the driver and caused tons of sense errors to
be reported.

This code is being checked in this area so others can help me get it into
shape to commit into the FreeBSD tree.  Assistance has been volunteered
by iXsystems.

We might want to re-work the JBOD attachment that creates /dev/mfisyspd?
node for each disk.

Performance is faster then prior cards.  It works okay with WITNESS
and INVARIANTS on amd64 and i386.  I recall seeing a use after
free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS
and INVARIANTS on.

First task is get all of the new structures to be named in FreeBSD
style format.

Next is probably to deal with the 64bit addressing changes that are
mostly around the #ifdef __amd64__ checks.

Thanks to LSI for providing the initial code.

c09808d0d6 MFtbemd:
Use MACHINE_CPUARCH in preference to MACHINE_ARCH.  The former is the
source code location of the machine, the latter the binary output.  In
general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target.  The isn't even moot for
i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86,
although a specific cleanup for that likely would be needed...

on an MFI controller.

741367d5a5 Add in a bunch of things to the mfi driver:
- Linux ioctl support, with the other Linux changes MegaCli
	will run if you mount linprocfs & linsysfs then set
	sysctl compat.linux.osrelease=2.6.12 or similar.  This works
	on i386.  It should work on amd64 but not well tested yet.
	StoreLib may or may not work.  Remember to kldload mfi_linux.
      - Add in AEN (Async Event Notification) support so we can
	get messages from the firmware when something happens.
	Not all messages are in defined in event detail.  Use
	event_log to try to figure out what happened.
      - Try to implement something like SIGIO for StoreLib.  Since
	mrmonitor doesn't work right I can't fully test it.  StoreLib
	works best with the rh9 base.  In theory mrmonitor isn't
	needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.

2e21a3ef7e Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name
is derived from the phrase 'MegaRAID Firmware Interface' used by LSI.  This
driver provides a block interface to logical disks on the card and a minimal
management device.  It is MPSAFE, INTR_FAST, and 64-bit capable.

Thanks to Dell for providing hardware to test with and IronPort for
sponsoring the work.
