rewrite ess mixer to use native registers
rewrite play/rec code to use more accurate timer when available
add code to use audio2 for playback, but disable it as no irqs are generated
to be based on the transfer speed, but I got it all wrong. The by far
biggest factor in the timeout is the start of a removable device, which
is about 2 seconds anyway.

address size that is different than the standard 6bits. This fixes
support for the Compaq NC3121 card, certain newer Intel Pro/100+
cards, and should also fix integrated NICs on SuperMicro and Compaq
motherboards.
The auto-sizing algorithm was taken from NetBSD (thanks!), which I
think got it from Linux originally.
Thanks also to Andrew Sparrow <spadger@best.com> and Joe Moore
<jomor@ahpcns.com> for supplying me with unworking Compaq and Intel
cards to develop and test the fixes with.
set properly in the struct buf with vinum:
Fix locations where B_READ was cleared in the old code but
b.b_iocmd wasn't set to BIO_WRITE
Fix propogation of b_iocmd
Correct comments to reflect reality
Don't compare b_flags with BIO_READ, it's in b_iocmd.

Remove RF_PCCARD_ATTR in anticipation of removing it from sys/rman.h
Add interface for setting "attributes" of pccard/cardbus devices.
Minor formatting nits.
timeout closer to the 1-second value that AMI use in their Linux
driver, and mark the mailbox structures as volatile so that gcc
doesn't over-optimise access to them.
This should fix the "controller wedged" bug.

* add a callback for initialising the mixer interface
* support ac97 2.1 variable rate audio feature
fix ac97-using drivers for the above
add suspend/resume support for neomagic
Make the public interface more systematically named.
Remove the alternate method, it doesn't do any good, only ruins performance.
Add counters to profile the usage of the 8 access functions.
Apply the beer-ware to my code.
The weird +/- counts are caused by two repocopies behind the scenes:
kern/kern_clock.c -> kern/kern_tc.c
sys/time.h -> sys/timetc.h

substitute BUF_WRITE(foo) for VOP_BWRITE(foo->b_vp, foo)
substitute BUF_STRATEGY(foo) for VOP_STRATEGY(foo->b_vp, foo)
This patch is machine generated except for the ccd.c and buf.h parts.
field in struct buf: b_iocmd. The b_iocmd is enforced to have
exactly one bit set.
B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue. It is likely to write on your disk
where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.
A lot of this patch were machine generated (Thanks to style(9) compliance!)
Vinum users: Greg has not had time to test this yet, be careful.
too many, so I removed the checks for the valid OUIs. We already do a
checksum of the entire ethernet address, so extra checking against the
OUI shouldn't be needed.
it's options COMPAT_OLDISA and COMPAT_OLDPCI. This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support. I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.
prevent a page fault if the card is ejected while BPF is in use. This
could happen if DHCP or tcpdump was in use on that interface during
ejection. Other drivers may also require this modification.

negotiation features (DT, ULTRA2, ULTRA, FAST). The offsets
where not properly updated when the DT entry was added and so
the driver could attempt to negotiate a speed faster than that

via SCSI-Select settings. *
o Update the target mode incoming command queue kernel index value
ever 128 commands instead of 32. This means that the kernel will
always try to keep its index (as seen on the card - the kernel may
actually have cleared more space) 128 commands ahead of where the
sequencer is adding entries.
o Use the HS_MAILBOX register instead of the KERNEL_TQINPOS location
in SRAM to indicate the kernel's target queue possition on Ultra2
cards. This avoids the "pause bug" on these cards and also turns
out to be much more efficient.
o When enabling or disabling a particular target id for target mode,
make sure that the taret id in the SCSIID register does not
reference an ID that is not to receive target selections. This
is only an issue on chips that support the multiple target id
feature where the value in SCSIID will still affect selection
behavior regardless of the values in the target id bit field
registers.
o Remove some target mode debugging printfs.
o Make sure that the sense length reported in ATIO commands is
always zero. This driver does not, yet, report HBA generated
sense information for accepted commands.
o Honor the CAM_TIME_INFINITY and CAM_TIME_DEFAULT values for
the CCB timeout field.
o Make the driver compile with AHC_DEBUG again.
