OUT status. We are, apparently, required to force the f/w to log back in

a LOGIN LOCAL LOOP PORT mailbox command, or by issuing a LIP. I've elected
to issue a LIP because this has a better chance of waking up the disk which
clearly just crashed and burned.

to be able to use 48bit addressing mode, but says the 48bit

address zero sectors in 48bit mode, why then say it supports
48bit mode at all..
If you want QLogic to look at a potential f/w problem for FC cards, you really
have to provide them info in the format they expect. This involves dumping
a lot of hardware registers (> 300 16 bit registers) and a lot of SRAM
(> 128KB minimum). Thus all of this code is #ifdef protected which will
become an option so that the memory allocation of where to dump the crash
image is pretty expensive. It's worth it if you have a reproducible problem
because they have some tools that can tell them, given the f/w version,
the precise state of everything.

Appologies for making this one bulk commit, but I have tested all these
changes together and don't want to break anything by trying to disentangle
it.
o Make debugging a sysctl/tunable
o Remove flags word from yenta chip info, it is unused
o Make 16-bit card I/O range and 32-bit card I/O range tunables
o Start the rename of pccbb to cbb to match NetBSD by misc renames.
o Kill the now bogus list of softcs to create kthread. Instead, just
create the kthread in the attach routine.
o Remove sc_ from some structure names. It isn't needed.
o Refine chipset lookup code.
o Match generic PCI <-> CardBus bridges. We specifically don't generically
match PCI PCMCIA bridges because they are not, with one exception, yenta
devices.
o Add some comments about the why we need to have a function table ala
OLDCARD
o The PCI interrupt routing by using the ExCA registers is needed for
for all bridges, per the spec, not just TI ones.
o Collapse TOPIC95 and TOPIC95B.
o Using the ToPIC 97 and 100 datasheets, try to support these bridges better,
but more work is needed.
o Generally clarify some XXX comments and add them in a few places where
things didn't look right to me.
o Move interrupt generating register access until after we establish an ISR.
o Add support for YV and XV cards. X and Y are numbers to be determined
later (but maybe never).
o factor powerup code for 16-bit and 32-bit cards.
o When a card supports more than one voltage, prefer the lowest supported
volage. Windows does this, and MS's design guides imply this is the
right thing to do.
o Document race between kthread_exit(0) and kldunload's unmapping of pages
that John Baldwin and I discovered.
o Debounce the CSC interrupt a little better.
o When a 16-bit card is inserted when we don't have a pccard child,
warn about it better. Ditto for 32-bit card.
o Ack ALL the interrupt bits that we get, not just 0x1.
o maybe a couple minor style nits corrected.
the structure definitions come from NetBSD to make it easier to share card

as simple as adding its definition to pucdata.c

Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.
A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.
Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.
Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.
Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.
If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

at insert time. When asking gibbs for approval for an MFC, this was
his reply:
1) It leaks memory if it can't allocate a path.
2) It defers allocation of aic->path until the call to scan the
bus. This means the path may be NULL when an interrupt occurs
prior to the call to scan the bus (stray bus reset for instance),
which will lead to a panic.
3) The driver in current doesn't recover from the failure to allocate
aic->path. The driver doesn't check during normal operation if
the path is NULL, so again a panic will result.
4) aic_cam_rescan calls malloc with M_WAITOK. aic_cam_rescan is called
from attach where it isn't necessarily safe to sleep.
5) And most importantly, it co-opts the xpt_periph from the driver level.
This was never part of the design (xpt_periph used to be static). Making
a call of this type may completely confuse the XPT if other XPT operations
are ongoing.
In the long term, Justin and Warner agreed to implement solution where
CAM itself will initiate the bus rescan if a new bus is added. For
the time being (and in particular in light of the upcoming 4.5
release), we now have camcontrol available on the boot floppy, and can
have pccardd initiate the rescan through it.

mutex releases to not require flags for the cases when preemption is
not allowed:
The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent
switching to a higher priority thread on mutex releease and swi schedule,
respectively when that switch is not safe. Now that the critical section
API maintains a per-thread nesting count, the kernel can easily check
whether or not it should switch without relying on flags from the
programmer. This fixes a few bugs in that all current callers of
swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from
fast interrupt handlers and the swi_sched of softclock needed this flag.
Note that to ensure that swi_sched()'s in clock and fast interrupt
handlers do not switch, these handlers have to be explicitly wrapped
in critical_enter/exit pairs. Presently, just wrapping the handlers is
sufficient, but in the future with the fully preemptive kernel, the
interrupt must be EOI'd before critical_exit() is called. (critical_exit()
can switch due to a deferred preemption in a fully preemptive kernel.)
I've tested the changes to the interrupt code on i386 and alpha. I have
not tested ia64, but the interrupt code is almost identical to the alpha
code, so I expect it will work fine. PowerPC and ARM do not yet have
interrupt code in the tree so they shouldn't be broken. Sparc64 is
broken, but that's been ok'd by jake and tmm who will be fixing the
