devices should work, but I cannot test this since my only ed card is
memory mapped.

I'm committing this from a laptop running this driver. Have only one
devclass for all ep devices (at least for pccard and eisa) so unit
numbering is sane. Might not work with both isa and non-isa devices
on the same system until ep is updated (Matt has some patches in the
pipeline which should resolve this, he wanted me to commit this so he
can resolve any conflicts against cvs rather than my patches).

This has not been reviewed by bde, so I'm committing to resolve any
issues he has with this when he returns from FreeBSD CON 99.
I've had four reports of this working for them. I've been able to
communicate to both my built in modem and a pccard modem with these
patches.

it has the same value on all platforms. Previously it was just under
3 seconds on x86 (typically hz<=128) and just under 1/3 of a second on
alpha (typically hz>=1024). This covers up a race between ad_interrupt()
and ad_timeout() which is being looked into.

bootup. Somehow my backout of an abortaive attempt at shared
memory autoconfiguration included this line:
sc->mem_shared = 1;
Which is fairly important as it turns out.
Since I performed my pre-commit testing on a different box with a generic
NE2000 I didn't catch this. Pointy hat.
Put splbio protection around the main launch loop. We've seen cases where
the bottom half was cutting off the branch on which we're sitting.

any more. Allocate transfer dma maps and xflist stuff in mbxdmasetup based
upon isp->isp_maxcmds. Allow for multiple calls to mbxdmasetup (for
isp_reset cases).
file later. Do some pencil-sharpening types of minor changes. Change
how active commands are remembered (using new inline functions to get
handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as
outgoing mailbox 2 will tell you the f/w's notion of the max commands
that can be supported. Attempt to retrieve loop topology. Add in the
appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little
Endian machines but is needed for sparc (on other platforms)). Move
the temp port database we use to find out where things have moved to
after a LIP to the softc and off the kernel stack. Follow Qlogic's
hint and don't bother setting a tag for commands that don't have
this enabled (presumably the f/w will do it's own selection then).
Use an INT_PENDING macro to check for an interrupt. The call to
ISP_DMAFREE now just takes the handle- not the 'handle-1' which was
a layering violation. Use CFGPRINTF in a couple of places to make
things less chatty if not booting verbose, or CAMDEBUG compiles, etc..
where it defaults to one. Change simq width allocation to the max number
of commands supported by the HBA after f/w fires up- not the constant
MAXISPREQUEST value. Do some stylistic changes.
Add in null SWIZZLE definitions. Add in CFGPRINTF define. Change default
debug level to refer to an external isp_debug variable. Remove inline
functions as they're now in isp_inline.h and include that file.
the result queue length is never less than 64. Move (ick) temp port
database used for post-LIP merging off the kernel stack and put it
into the softc. Remove some target mode stuff which will come back
later in a different file. Change how the list of outstanding commands
are stored (now allocated at mailbox setup time to be just enough for
the max for a specific HBA which can vary). Keep a rotating seed of
the last index for this in the softc. Increase the count of active
commands from 10 to 16 bits.

I feel less dirty now.
In order to make this work, I created a pseudo-PHY driver to deal with
Macronix chips that use the built-in NWAY support and symbol mode port.
This is actually all of them, with the exception of the original MX98713
which presents its NWAY support via the MII serial interface.
The mxphy driver actually manipulates the controller registers directly
rather than using the miibus_readreg()/miibus_writereg() bus interface
since there are no MII registers to read. The mx driver itself pretends
that the NWAY interface is a PHY locayed at MII address 31 for the sole
purpose of allowing the mxphy_probe() routine to know when it needs to
attach to a host controller.
32 bytes is safe.
Handle successful completion of message log retrieval commands.
With these changes, the driver correctly handles the consequences of drive
death and replacement in a reliable array. Note that the massive backlog
of I/O during handling of such an event can kill the system if softupdates
is enabled.
Without it the kernel config options, like OVERRIDE_TUNER, where not

PJ cards. This will probably also support the AcceleRAID and
eXtremeRAID cards, but nobody has volunteered one for testing, so I
haven't enabled their PCI device IDs.
Slightly clean up communication between the disk devices and the
controller device as per new practice, and move some more register-

Remove some unnecessary read-modify-write operations to the card
control registers; they don't behave like that.
Increase the status polling interval to 10 seconds. It's still possible
to load the card up to the point where a status poll will find the
previous poll still running, but this will reduce the incidence of
complaints.
