messages and the dev.aac.0.%desc sysctl.

to trip a bug causing the latter to return a zeroed struct
aac_adapter_info. This causes two issues. One is cosmetic only --
a verbose boot prints information about the controller, and shows all
zero:
aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
unknown battery platform
The second problem is that the firmware version information is stored
away for aac_rev_check, for userland tools (like aaccli) to query via
the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
When aaccli encounters this issue it prints
Command Error: <The current AFAAPI.DLL is too old to work with the
current controller software.>
Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
which seems to fix both problems.
- Resource allocation in aac_alloc (moved from from aac_init)
- Interrupt setup in aac_setup_intr (from aac_attach)
- Container probing in aac_get_container_info (from aac_startup and
aac_handle_aif)
- Firmware status check moved to aac_check_firmware from aac_init
putting the correct size in the fib header. Presumably the older firmware
silently ignored a bad size field.
(This change tested with a 3805 controller. Passthrough devices were
created when running firmware build 12814, but not 15323 or later. With
this change they're created for both old and new firmware versions.)

FSACTL_LNX_SEND_LARGE_FIB, and FSACTL_LNX_SEND_RAW_SRB, and correct size
checks on FIBs passed in from userspace. Both changes were obtained from
Adaptec's driver build 15317. Adaptec's commandline RAID tool arcconf uses
these ioctls when creating a RAID-10 array (and probably other operations
too).

Thos makes way for us to add REAL kthread_create() and friends

calls actually end up being moved back to the thread version

I'd LOVE to do this rename in 7.0 so that we can eventually MFC the

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to

This approach is used by some other drivers as well. However, we
need a more generic way to do this in order to avoid having to
special case headers in individual drivers for each platform.

the CAM_NEW_TRAN_CODE that has been in the tree for some years now.
This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).
After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.
This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

the modified interface that they use. Changes include:
- Register a different interrupt handler for the new interface. This one is
INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs.
- Add an event registration and callback mechanism for the ioctl and CAM
modules can know when a resource shortage clears. This condition was
previously fatal in CAM due to programming oversights.
- Fix locking to play better with newbus.
- Provide access methods for talking to cards with the NEWCOMM interface.
- Fix up the CAM module to be better suited for dealing with newer firmware
on the PERC Si/Di series that requires talking to plain SCSI via aac.
- Add a whole slew of new PCI Id's.
Thanks to Adaptec for providing an initial version of this work and for
answering countless questions about it. There are still some rough edges in
this, but it works well enough to commit and test for now.

risky because the "current time" is supposed to be fed to the card during
initialization, and the current time is supposed to be put into each command
that is sent to the card. Hopefully either the card doesn't actually care
about the timestamps, or it doesn't care about the absolute values so long
and the relative values are consistent. Not an MFC candidate until more
thorough testing can be done.

protect the registers so it was trivially possible for a sync command and
i/o command to fight each other and confuse the controller. Make the
sync fib alloc/release functions inline and remove the somewhat worthless
AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track
this down in RELENG_4.
every iteration of aac_startio(). This ensures that a command that is
deferred for lack of resources doesn't immediately get retried in the
aac_startio() loop. This avoids an almost certain livelock.
only done minimal testing on one of these cards and the firmware folks
have been extremely uncooperative in answering my qeustions about them, so
hopefully they will work ok for everyone.
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.
Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.
Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.
Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:
The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT
A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.
Manual page update to follow shortly.
on the card, unmap it first. This allows it to be picked up properly when
the queue gets kicked again. This was the root problem for the lost command
(i.e. stuck in getblk/vinvalb) problem. While here, panic if commands don't
map correctly instead of just silently ignoring the problem and dropping
command. Also slow down the dynamic allocation of new commands.
It should be safe to go back into the aac waters. Thanks to everyone who
suffered through this and provided good feedback.
