fall within the first 256MB of memory. The origin/reason for that
limitation is not known, but it's not believed to be required for
proper initialization. What is known is that the Altix 350 does not
have physical memory at that address (by virtue of the address space
bits).
Keep the boundary at 256MB so that the info block will be covered
by a single direct-mapped translation.
While here, change the flags to M_NOWAIT to eliminate confusion. It
does not change the behaviour of contigmalloc(). What is does is
makes the flags argument explicitly say what the actual behaviour
is.
memory descriptor, don't return NULL as the virtual address, return the
direct-mapped uncacheable virtual address for it. At first, this was
needed only for the Altix 350, but now even some high-end HP machines
have devices mapped to physical addresses that aren't covered by the
EFI memory map.
The racct code in sys_munlock() assumed that the boundaries provided by the
userland were correct as long as vm_map_unwire() returned successfully.
However the latter contains its own logic and sometimes manages to do something
out of those boundaries, even if they are buggy. This change makes the racct
code to use the accounting done by the vm layer, as it is done in other places
such as vm_mlock().
Despite fixing the panic, Alan Cox pointed that this code is still race-y
though: two simultaneous callers will produce incorrect values.

System panics during a Port reset with ouststanding I/O
---------------------------------------------------------------
It is possible to call mps_mapping_free_memory after this
memory is already freed, causing a panic. Removed this extra
call to mps_mappiing_free_memory and call mps_mapping_exit
in place of the mps_mapping_free_memory call so that any
outstanding mapping items can be flushed before memory is
freed.

Correct memory leak during a Port reset with ouststanding I/O
---------------------------------------------------------------
In mps_reinit function, the mapping memory was not being
freed before being re-allocated. Added line to call the
memory free function for mapping memory.

Use CAM_SIM_QUEUED flag in Driver IO path.
---------------------------------------------------------------
This flag informs the XPT that successful abort of a CCB
requires an abort ccb to be issued to the SIM. While
processing SCSI IO's, set the CAM_SIM_QUEUED flag in the
status for the IO. When the command completes, clear this
flag.
---------------------------------------------------------------
Check for CAM_REQ_INPROG in I/O path.
---------------------------------------------------------------
Added a check in mpssas_action_scsiio for the In Progress
status for the IO. If this flag is set, the IO has already
been aborted by the upper layer (before CAM_SIM_QUEUED was
set) and there is no need to send the IO. The request will
be completed without error.
---------------------------------------------------------------
Improve "doorbell handshake method" for mps_get_iocfacts
---------------------------------------------------------------
Removed call to get Port Facts since this information is
not used currently.
Added mps_iocfacts_allocate function to allocate memory
that is based on IOC Facts data. Added mps_iocfacts_free
function to free memory that is based on IOC Facts data.
Both of the functions are used when a Diag Reset is performed
or when the driver is attached/detached. This is needed in
case IOC Facts changes after a Diag Reset, which could
happen if FW is upgraded.
Moved call of mps_bases_static_config_pages from the attach
routine to after the IOC is ready to process accesses based
on the new memory allocations (instead of polling through
the Doorbell).

Prefer mps_wait_command to mps_request_polled
---------------------------------------------------------------
Instead of using mps_request_polled, call mps_wait_command
whenever possible. Change the mps_wait_command function to
check the current context and either use interrupt context
or poll if required by using the pause or DELAY function.
Added a check after waiting 50mSecs to see if the command
has timed out. This is only done if polliing, the msleep
command will automatically timeout if the command has taken
too long to complete.

Integrated RAID: Volume Activation Failed error message is

Instead of failing an IOCTL request that does not have a

Add a PIM_NOSCAN flag to the CAM path inquiry CCB. This tells CAM
not to perform a rescan on a bus when it is registered.
We now use this flag in the mps(4) driver. Since it knows what
devices it has attached, it is more efficient for it to just issue
a target rescan on the targets that are attached.
Also, remove the private rescan thread from the mps(4) driver in
favor of the rescan thread already built into CAM. Without this
change, but with the change above, the MPS scanner could run before
or during CAM's initial setup, which would cause duplicate device
reprobes and announcements.

sys/cam/cam_xpt.c:
Added a PIM_NOSCAN flag. If a SIM sets this in the path
inquiry ccb, then CAM won't rescan the bus in

For versions of FreeBSD that have the PIM_NOSCAN path
inquiry flag, don't freeze the sim queue during scanning,
because CAM won't be scanning this bus. Instead, hold
up the boot. Don't call mpssas_rescan_target in
mpssas_startup_decrement; it's redundant and I don't
know why it was in there.
Set PIM_NOSCAN in path inquiry CCBs.
Remove methods related to the internal rescan daemon.
Always use async events to trigger a probe for EEDP support.
In older versions of FreeBSD where AC_ADVINFO_CHANGED is
not available, use AC_FOUND_DEVICE and issue the
necessary READ CAPACITY manually.
Provide a path to xpt_register_async() so that we only
receive events for our own SCSI domain.
Improve error reporting in cases where setup for EEDP
detection fails.
sys/dev/mps/mps_sas.h:
Remove softc flags and data related to the scanner thread.

DB120 development board.
The AR934x SoCs are a MIPS74k based system with increased RAM addressing
space, some scratch-pad RAM, an improved gige switch PHY and 2x2 or 3x3
on-board dual-band wifi.
This support isn't complete by any stretch; it's just enough to bring
the board up for others to tinker with. Notably, the MIPS74k support
is broken. However it boots enough to echo some basic probe/attach
messages, before dying somewhere in the TLB code.
Thankyou to Qualcomm Atheros for their continued support of me doing
open source work with their hardware.
Tested:
* AR9344, mips74k
This code reads the PLL configuration registers and correctly programs
things so the UART and such can come up.
There's MIPS74k platform issues that need fixing; but this at least brings
things up enough to echo stuff out the serial port and allow for interactive
debugging with ddb.
Tested:
* AR71xx SoCs
* AR933x SoC
* AR9344 board (DB120)
Obtained from: Qualcomm Atheros; Linux/OpenWRT
For all pre-AR933x chips, the frequency is just the APB frequency.
For the AR933x, the UART frequency is different but we just hacked around
it.
For the AR934x, there's a different PLL setting for these, so they have
to be broken out.
