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.

- 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!

down some DCMD's without any data. Thanks to Dell and LSI for helping
to provide clues to figure out this problem. Now MegaCli can upgrade
the firmware and should work identical when run on Linux.

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.
- Fix the locking protocol to eliminate races between normal I/O and AENs.
- Various small improvements and usability tweaks.

AEN. This makes the boot messages cleaner. I now know how this
structure works so I can implement it versus guessing. Remove the
not ready type code since it is ready now.
I added the time stamp/locale/class so people can parse messages better.
Create a sysctl so that we can set the locale/class level.
- 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.

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.
