EISA slots to probe. This is mainly intended to allow installing the
system on an HP Netserver with an on-board AIC7xxx EISA SCSI
controller, that is sitting on EISA slot # 11.
Documentation updates explaining this hack will follow shortly.
Note that this can go away again as soon as the EISA device probing
is more intelligent about the address space clash with the PCI address
space.

non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().
to miss reselections from some devices and since the reselection response

problem.
function ed_attach_NE2000_pci() in if_ed.c passes
an uninitialized block of memory (got with malloc())
to ed_attach. This prevents a proper initialization
of the device descriptor and in my case causes a panic
during the probe, while printing out device info.

1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.
2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).
3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.
The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)
4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.
5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

a) Removal of private typedefs tulip_uint*_t, use standard u_int_*_t.
b) Change [Dd][Cc]21.4. to just 21.4., seems Dec has done this to all
of the drivers for all OS's. (Did they get in trouble with someone?)
[The few that remain can either not be eliminated, or are waiting for
additional driver functional changes that will remove them.]
c) Move some code from dc21040.h into the driver, later a whole block of that
code and more will move to devar.h, but for now this makes it easier
to study diffs.
d) Add a big bold comment to the README.de file about it not reflecting
reality anymore.
Note that these are all cosmetic changes and should be no functional
change in the driver whatsoever. If _anyone_ spots a problem introduced

Immediate SCBs, since they always send messages that tell the target to
transition to bus free now rely on the busfree interrupt instead of the
IMMEDDONE sequencer interrupt that was generated before.
Rearrange some code in the message out loop to give ATN a little more time
to drop before we ACK the last byte.
Use SPIORDY instead of REQINIT when snooping for a tag message on a reconnect.
This is done for the same reasons we use SPIORDY in the inb functions.
When going into BITBUCKET mode, turn off HDMAEN in the DFCNTRL register so
that we can "not care" what the value of HCNT is. If HCNT is 0, BITBUCKET
mode won't transfer any data if HDMAEN is set. Seeing as we don't want the
transfer to even think about touching the host, this seems more sane anyway.
Thanks to "Dan Willis" <dan@plutotech.com> for pointing out that this was
a problem.
SPIORDY should go active on any REQ of the bus, so testing for REQINIT is
not necessary. It also seems that testing for SPIORDY is more robust then
REQINIT since SPIORDY comes active after REQINIT and PHASEMIS seems to take
some time to come true after REQ is asserted if the phase has changed. Of
course, none of this is documented.
This should give the code savings of my original changes, without breaking the
driver on fast peripherals.
The 'getchar' function in syscons (sccngetc) is used by UserConfig to
get keyboard input from the user. When it was modified to use the
shared keyboard port routines it used the port passed in during the
probe routine. Since the probe routine was not yet called, the port was
set to 0, which is obviously not going to work.
Pre-initialize sc_port to IO_KBD which is really a kludge, but it's how
the previous driver did it's job.

Hopefully fix the hangs in the mesgin and mesgout phases that I introduced

Add a pause disable in the SCB paging case around our manipulation of the

Set LASTPHASE to P_BUSFREE once we see a busfree so that the kernel driver can

me. This contains an update of the psm driver as well.
This also fixes the breakage that I introduced to the psm driver by
making syscons poll for keyboard events in the atempt to fix the
hanging keyboard problem.
It works perfectly for me, and I'd like to hear from all that
have had keyboard/ps/2 mouse problems if this is the cure...

2. Fixed code to match comment in scintr().
3. Don't allow even root to take control of the machine when securelevel > 0.
I've secured the accesses to PSL_IOPL in all drivers and asked pst to
review it, but he seems to be busy. Write access to /dev/kmem and
other critival devices currently leaks across raisings of securelevel
via open fd's, so there may as well be a similar leak for PSL_IOPL.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.
Especially the 3c59X support should be pretty stable now.
