15c761840a Release summary: (detailed descriptions in Edit History in matcd.c)
Adds support for non-Sound Blaster host adapters, including those
distributed by Reveal, Lasermate, IBM, Media Vision, Crystal and others.
The driver automatically senses the correct adapter type and you can
have both in the system at the same time.
(This change should eliminate a few complaints.)

Corrected bit-masking problem that prevented use on SB Vibra-16 boards.

Declared some internal data and functions static that should have been
that way all along.

Documentation changes reflect the new hardware support and change the
appearance version to 2.0.5 (was 2.1).    Nice and tidy.   :-)


Beta testers have verified functionality on SB16, Vibra-16, Media Vision
and Reveal adapters.   -Wall still shows no warnings.

- provide the same features and interface as sio
- support multiple boards
- fix bugs.

9f77221854 Protected entire epioctl routine with splimp(). In this case, it is better
form to do this than it is relying on individual subroutines (the logic
in epioctl is itself very minimal). Ideally, unnecessary splimp()'s should
now be removed if they exist; I'll leave this for a later date (a complete
code review of the driver needs to be done). Fixes a bug I noticed that
would show up when ifconfig'ing the interface down.

6b172e59a6 First pass cleanup of this driver. This pass does not include the sequencer
optimizations I have been working on yet, but does bring in some bug fixes
and performance improvments that were easy to regression test:

Setup the data fifo threshold and bus off timing correctly for 27/284x cards.
Users of these adapters with fast periferals (greater than 5MB/s) will notice
a big performance difference. (Sometimes as large as going from 3.7->8.3MB/s).

Fix handling of the active target flags.  Some of the outbs where missing
the base offset in the abort code.  The abort code still needs lots of work.

Support 3940 controllers, but only with 16 SCBs for now.  Eventually I'll
add support for all 255, but I need to find a tester for the code first since
we have to enable the cards external SRAM to do this.

Add Dan Eischen's serial eeprom reading facilities.  This allows the 2940
adapters to pull additional information left over from SCSI-Select right out
out of the configuration seeprom.

If the BIOS is disabled on 274x controllers, reset all target parameters
to there defaults since you can't rely on what is stored in scratch ram.

Report motherboard controllers as such.

Stick the first SG address and count into the SCB data and count areas for
all transfers in preparation of a later sequencer optimization.

Keep track of which targets can are allowed to have the disconnection
priveledge since this will be handled by the kernel driver in the future.

If a target issues a message reject in response to a tagged message,
disable tagged queuing for that target.  Some seagates say they can do
tagged queuing, but lie, and its a shame to have to disable tagged queuing
on all devices just because you have one that can't cope.

aren't #undef'ed when the corresponding typedef is declared.
off_t is very machine-dependent and should never have been decided
in <sys/types.h> (its declaration is compiler-dependent).  pid_t
isn't very machine-dependent, but this might change.  `long' is
a wasteful type for it if longs are longer than ints.

c21dee177f First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.

33dc7e1b84 Reduce timeout frequency from `hz' to 0 if no ports are open or to 1 if
no ports are active, provided there are no polled ports and no
`LOSESOUTINTS' ports.  Do a little more in the interrupt handler instead.
This is a little less efficient if there are are many active ports but
a little more efficient otherwise.  Polled ports are ones with no irq
specified (as before).  `LOSESOUTINTS' ports are ones with 0x08 set in
their config flags.  Unless this flag is set, it will now take up to one
second to recover from lost output interrupts, if any.  Some 8250s and
16450s lose output interrupts.

Improve output buffering: copy the clist buffer to 2 linear buffers if
necessary and possible instead of to 1.  Handle an arbitrary queue of
buffers in the interrupt handler.  Check for waking up sleepers after
copying characters out of the clist buffer instead of before.

Delay translation of TIOCM_DTR to MCR_DTR etc. so that the top level
routines are more machine independent.

This file is very incomplete.  In particular, it doesn't mention any
network cards.  This doesn't matter much for the base addresses, but
it means that the comments about which addresses are free are mostly
bogus.  The i/o sizes are unreliable because of split address ranges
for many devices (VGA, wd).  The i/o sizes are incomplete.  In
particular, there are no sizes for SCSI controllers.  The bt driver
still returns a truth value instead of a size.

ac8d676972 Fix setdumpdev():
- the major number wasn't checked, so accesses beyond the end of bdevsw[]
  were possible.  Bogus major numbers are easy to get because `sysctl -w'
  doesn't handle dev_t's reasonably - it doesn't convert names to dev_t's
  and it converts the number 1025 to the dev_t 0x35323031.
- Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV
  (the interface is too braindamaged to say which).  -1 was interpreted
  as a size and resulted in the bogus error ENOSPC.
- it was possible to set the dumpdev for devices without a d_psize()
  function.  This is equivalent to setting the dumpdev to NODEV except
  it confuses sysctl.
- change a 512 to DEV_BSIZE.  There is an official macro dtoc() for
  converting "pages" to disk blocks but it is never used in /usr/src/sys.
  There is much confusion between PAGE_SIZE sized pages and NBPG sized
  pages.  Maxmem consists of both.

Not fixed:
- there is nothing to invalidate the dumpdev if the media goes away.
  This reduces the benefits of the early calculation of dumplo.  Bounds
  checking in the dump routines is relied on to reduce the risk of
  damage and little would be lost by relying on the dump routines to
  calculate dumplo.
- no attempt is made to stay away from the start of the device to
  avoid clobbering labels.

Fix wrong && anachronistic comment about the type of bootdev.

57cb71573d Fixes to the aic7xxx sequencer code and device driver from Justin Gibbs:
1) If a target initiated a sync negotiation with us and happened to chose a
value above 15, the old code inadvertantly truncated it with an "& 0x0f".
If the periferal picked something really bad like 0x32, you'd end up with
an offset of 2 which would hang the drive since it didn't expect to ever
get something so low.  We now do a MIN(maxoffset, given_offset).

2) In the case of Wide cards, we were turning on sync transfers after a
sucessfull wide negotiation.  Now we leave the offset alone in the per
target scratch space (which implies asyncronous transfers since we initialize
it that way) until a syncronous negotation occurs.

3) We were advertizing a max offset of 15 instead of 8 for wide devices.

4) If the upper level SCSI code sent down a "SCSI_RESET", it would hang the
system because we would end up sending a null command to the sequencer.  Now
we handle SCSI_RESET correctly by having the sequencer interrupt us when it
is about to fill the message buffer so that we can fill it in ourselves.
The sequencer will also "simulate" a command complete for these "message only"
SCBs so that the kernel driver can finish up properly.  The cdplay utility
will send a "SCSI_REST" to the cdplayer if you use the reset command.

5) The code that handles SCSIINTs was broken in that if more than one type
of error was true at once, we'd do outbs without the card being paused.
The else clause after the busfree case was also an accident waiting to
happen.  I've now turned this into an if, else if, else type of thing, since
in most cases when we handle one type of error, it should be okay to ignore
the rest (ie if we have a SELTO, who cares if there was a parity error on
the transaction?), but the section should really be rewritten after 2.0.5.
This fix was the least obtrusive way to patch the problem.

6) Only tag either SDTR or WDTR negotiation on an SCB.  The real problem is
that I don't account for the case when an SCB that is tagged to do a particular
type of negotiation completes or SELTOs (selection timeout) without the
negotiation taking place, so the accounting of sdtrpending and wdtrpending
gets screwed up.  In the wide case, if we tag it to do both wdtr and sdtr,
it only performs wdtr (since wdtr must occur first and we spread out the
negotiation over two commands) so we always have sdtrpending set for that
target and we never do a real SDTR.  I fill properly fix the accounting
after 2.0.5 goes out the door, but this works (as confirmed by Dan) on
wide targets.

Other stuff that is also included:

1) Don't do a bzero when recycling SCBs.  The only thing that must explicitly
be set to zero is the scb control byte which is done in ahc_get_scb.  We also
need to set the SG_list_pointer and SG_list_count to 0 for commands that do
not transfer data.

2) Mask the interrupt type printout for the aic7870 case.  The bit we were
using to determine interrupt type is only valid for the aic7770.

14c77d8a98 After carefully reading three reference documents, and analyzing
the 802.3 frames generated by the DC21040 (which does automatic padding
of less-than-minimum frames) and the frames generated by the 'ed'
driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN"
as reported by several people, John Hay being the most recent. The driver
was actually setting the length to 6+6+2+50 (64 bytes), which when adding
in the CRC (which is automatically appended to the frame and not included
in the length), the minimum frame is 4 bytes larger than it is supposed to
be. All of this is confirmed by tcpdump showing 50 bytes of data for
minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This
analysis has also revealed that there is garbage in the un-filled in
portion at the end of the minimum frames from the 'ed' driver; I don't
plan to fix this.

a401ebbe32 Changed swap partition handling/allocation so that it doesn't
require specific partitions be mentioned in the kernel config
file ("swap on foo" is now obsolete).

From Poul-Henning:

The visible effect is this:

As default, unless
        options "NSWAPDEV=23"
is in your config, you will have four swap-devices.
You can swapon(2) any block device you feel like, it doesn't have
to be in the kernel config.

There is a performance/resource win available by getting the NSWAPDEV right
(but only if you have just one swap-device ??), but using that as default
would be too restrictive.

The invisible effect is that:

Swap-handling disappears from the $arch part of the kernel.
It gets a lot simpler (-145 lines) and cleaner.

- Do the right thing when booting in NFS diskless mode, which is nothing.
  Make the default unconfigured entries for swdevt[0] and dumplo something
  that swapconf() will ignore and not choke on (the swap setup is done
  in nfs_vfsops.c when booting diskless).

d81fba0cda Add variable `idelayed' and macros setdelayed() and schedsofttty()
to access it.  setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.

Call setdelayed() every (normal) clock tick to convert delayed
interrupts into pending ones.

Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick.  This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.

2c739e6439 If you config a kernel with 'config kernel swap generic' and try to
boot diskless with it, you get a panic because setconf() is only
called for mountroot == ffs_mountroot. It really needs to be called
no matter what manner of rootfs we have. I can't really say if
swapgeneric will work with a CD-ROM though. (I get the feeling I'm
the only one who uses swapgeneric these days anyway.)

Correct all but 1 -Wformat warning.  Some would have caused garbage to
be printed due to missing args!

dac9a9e66d Fix numerous bugs in wdsize().
It closed the wrong device (usually the B partition instead of the C
partition).
It closed a device without having opened it.
It didn't open a device often enough.  This caused swap partitions on
slices other than the first slice looked at to be unavailable for swapping.
It didn't check the device number sufficiently.

The ``flags 1'' in the fdc line is now only needed for owners of an
Insight tape (perhaps there aren't any?  Mine is disfunctional).  All
other probes are safe wrt. to the motor-control line of floppy disk
drives.  Document the flag in LINT finally.
