r282533 : Corrected indentation on conflicted source files.
r282532 : Configured the mrsas(4) driver to support UNMAPPED I/O and updated driver version.
r282531 :
1. All LSI namings are converted to AVAGO Tech.
2. Fix in AEN path(suggested by John Baldwin).
3. Fix IOCTL path w.r.t Sense key handling
r282530 :
Bug fixes found internally as detailed below:
1. While disabling interrupt the FW disables interrupts for only 16 vectors.
In case of Invader which supports 96 MSI-x vectors, some spurious interrupts
may come on other vectors even after interrupt disable. So, driver uses a flag
and ignores the spurious interrupts.
2. Reply queue depth is made double the number of commands supported by FW.
3. Misplaced interrupt enable code is now moved down in the OCR path.
4. Updated error handling code in OCR path.
5. Removed un-necessary print.
r282529 :
Driver calls mrsas_complete_cmd() to call mrsas_wakeup() for each MFI frame that was
issued through the ioctl() interface prior to the kill adapter. This ensures
userspace ioctl() system calls issued just before a kill adapter don't get stuck in
wait state and IOCTLs are returned to application.
r282528 :
In OCR(Online Controller Reset) path, driver sets adapter state to
MEGASAS_HBA_OPERATIONAL before getting new RAID map.
There will be a small window where IO will come from OS with old RAID map.
This patch will update adapter state to MEGASAS_HBA_OPERATIONAL,
only after driver has new RAID map to avoid any IOs getting build using old RAID map.
r282527 :
Current driver does fast path read load balancing between arm and mirror disk
for two Drive Raid-1 configuration only.
Now, Driver support fast path read load balancing for all (any number of disk) Raid-1 configuration.
r282526 :
Now Driver expose Secure Jbod Support via driver_operations in MFI INIT Frame.
FW expose Secure Jbod support via Controller properity.
Firmware expect IOs to be received from different IO path than
conventional fast path queue, in case of SED drives.
To have Secure jbod support user need driver and firmware support.
r282525 : This patch adds the feature to provide PCI information via IOCTL query.

r270973
Fix for WITNESS warning while doing xpt_rescan.
This happen when converting any JBOD to RAID or creating
any new RAID from Unconfigured Drives.
Without this fix, user may see call trace if WITNESS is enabled.
System may panic when reconfiguring the RAID.

dd mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.
mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).
It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).
Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.
Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.
