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
supported by the target device or even requested by the user
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.

-current. It doesn't work yet as stable as the 3.x/PAO version of the
driver does, however, i get occasional `FDC direction bit not set' and
other weird messages, but it basically works at least.
The old (defunct) #ifdef FDC_YE stuff has been eliminated completely
now, PCMCIA-FDC specific functions have been implemented differently
where needed.
Unfortunately, due to the fact that the traditional PeeCee FDC with
its funny non-contiguous register space (one register for WD1003
harddisk controllers is interleaved into the FDC register set), and
Peter's subsequent changes involving two different bus space handles
for normal FDCs, the changes required for the Y-E stuff are more
complex than i'd love them to be. I've done my best to keep the logic
for normal FDCs intact.
Since the Y-E FDC seems to lose interrupts after a FDC reset
sometimes, i've also replaced the timeout logic in fd_turnoff() to
generate an artificial pseudo interrupt in case of a timeout while the
drive has still outstanding transfers waiting. This avoids the total
starvation of the driver that could be observed with highly damaged
media under 3.x/PAO. This part of the patch has been revied by bde
previously.
I've fixed a number of occasions where previous commits have been
missing the encapuslation of ISA DMA related functions inside
FDC_NODMA checks.
I've added one call to SET_BCDR() during preparation of the format
floppy operation. Floppy formatting has been totally broken before in
3.x/PAO (garbage ID fields have been written to the medium, causing
`wrong cylinder' errors upon media reading). This is just black
magic, i don't have the slightes idea _why_ this needs to be but just
copied over the hack that has been used by the PAO folks in the normal
read/write case anyway.
The entired device_busy() stuff seems to be pointless to me. In any
case, i had to add device_unbusy() calls symmetrical to the
device_busy() calls, otherwise the PCMCIA floppy driver could never be
deactivated. (As it used to be, it caused a `mark the device busier
and busier' situation.) IMHO, all block device drivers should be
marked busy based on active buffers still waiting for the driver, so
the device_unbusy() calls should probably go to biodone(). Only one
other driver (whose name escapes me at the moment) uses device_busy()
calls at all, so i question the value of all this...
I think this entire `device busy' logic simply doesn't fit for PCMCIA
&al. It cannot be the decision of some piece of kernel software to
declare a device `busy by now, you can't remove it', when the actual
physical power of removing it is the user pulling the card. The
kernel simply has to cope with the removal, however busy the device
might have been by the time of the removal, period. Perhaps a force
flag needs to be added?
Upon inserting the card a second time, i get:
WARNING: "fd" is usurping "fd"'s cdevsw[]
WARNING: "fd" is usurping "fd"'s bmaj
I suspect this is related to the XXX comment at the call to
cdevsw_add(). Does anybody know what the correct way is to cleanup
this?

- IBM ScrollPoint: 2 buttons on top and a stick between the buttons.
The stick can perform "horizontal scroll" in W*ndows environment.
The horizontal movement of the stick is detected. It is currently
mapped to the Z axis movement in the same way as the first wheel.
The mouse is recognized as "MouseMan+", as it is considered to be
a variation of MouseMan.
- A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement
of the second wheel is reported as the Z axis movement in the
same way as the first wheel. These mice are recognized as "4D
Mouse" and "4D+ Mouse".
- Tweak IntelliMouse support code a bit so that less-than-compatible
wheel mice can work properly with the psm driver.
- Add driver configuration flags which correspond to the kernel
options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't
need to recompile the kernel when we need these functions.
- Properly keep track of the irq resource.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).
- Properly keep track of resources (I/O ports and irq).
- Use bus_space_read/write() to access the ports.
- Add PnP IDs.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).
this version include:
- Support for version 2.x firmware (2.42 or later recommended). This
means we are the only open-source driver supporting these adapters.
This code has only been tested on a Digital KZPCA adapter in an Alpha
system, but is believed to be correct. NOTE: EISA adapters are not
yet supported.
- Support the BIOS/Firmware initialisation handshake protocol. This
allows the driver to bring the card up to operational state even if
the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system).
- A working command pasthrough interface. This allows a user-space
configuration tool (under development) to issue arbitrary commands
to the controller or to devices in the system.
platform we're running on so we know how many bits to reserve at the top
end for the 'hose' value. It turns out that there's *just* enough room
to support all possible hoses on TurboLaser.

This makes it possible to handle the done queue even when the end of tail
TD has ended up on the done queue as well (the xfer in this case is NULL
but the next field is valid, so we simply skip that element.
Make sure we mark all the handled transfers as handled.
Stop using powerhooks. They are a NetBSD-ism.

Add a few more register definitions for use with this and other new code.

we get the com address. If so, we go ahead and return. Bruce thinks
there's a bug in the pccard layer that it terminates devices with
extreme prejustice rather than letting them deside for themselves when
to terminate (and he's likely right). This fix doesn't change that,
but instead works around it by checking for NULL pointers at more
places than before.
The detach routine still calls functions at interrupt level that
aren't reentrant. In theory this could cause a problem, but none
showed up in practice. Future versions should correct this problem,
likely by making the detach process a thread/process at the pccard
level. NEWCARD will do this, and the current pccard layer should
likely be modified to that as well, should it live long enough.
A few style nits of the same form that were in my original patch sent
off to bde were also fixed as part of this process. Mostly use of
!ptr and return ENOPARENS.
This should prevent a crash on suspend with an active ppp link as
well, but that wasn't tested.

requires current and desired network parameters, so I have created a network parameter structure and used two on them in the softc. This gives a bit of room of expansion. Re-wrote the update check in _net to work with this.
Tidyed up softc due to above.
Removed startccs and startcmd as they were only used by NetBSDs startup timeout.
