718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

7e4dd9e112 Move struct megasas_sge from mfi_ioctl.h to mfivar.h so we can
remove including machine/bus.h.  Add some more mfi_ prefixes to
avoid name space pollution.

This should address the last tinderbox issues.

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.

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.

fa1e6ef4ef - Fix from jhb for failing I/O request when bus_dmamap_load fails.
- Fix to ioctl path in which the length could be 0 which means
  no data in/out from LSI.
- Fix to ioctl path in which the data in the sense data space
  of the ioctl packet is a really a pointer to some location in
  user-space.  From LSI re-worked a bit by me.
- Add HW support for next gen cards from LSI.

Thanks to LSI for their support!

46fb79ea72 Add support to talk to the LSI ioctl path on with FreeBSD 32 bit app's
on amd64.  Note the only difference is the iovec32 part so I use the
native structure for everything else.

Also I plan to MFC all the changes in -current to 7-stable and 6-stable
shortly since I've been running them.  This does not include the cam
changes.

0929b66905 Add support for management apps. Work around an apparent firmware bug that
results in hung i/o if more than 128 commands are scheduled for an array.

ddfae47b9d Collapse the mfi_ld object. Add an ioctl to help management apps map
array Id's to FreeBSD device names.

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
the firmware via the ioctl path so we don't do it in polled mode.

c2be47f25f - Add in FreeBSD native ioctl that models the Linux version.
- Add a translation so the Linux ioctl's don't conflict with
  the FreeBSD definition.
- Assume Linux 32bit emulation on amd64.
This was tested on i386 and amd64 with the 32bit Linux MegaCli.
Eventually we should do a 32bit native FreeBSD translation app.

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.
