0a44712261 Implement SCB paging. This allows up to 255 active commands on
aic7770 >= Rev E, aic7850, aic7860, aic7870, and ai7880 based controllers.

Make findSCB safer for non-tagged commands when tagged commands are
active on the controller.  The symptoms of this problem were
"Overlapped commands attempted" messages during error recovery
attempts.

Compact scratch ram usage.  This leaves 8 bytes free for future use.

Clean up some comments.

10d245c58a Yet more b_flags fixes. The previous ones broke the clearing of B_DONE
and B_READ before writing.  This was was fatal.  They also broke the
clearing of B_INVAL before doing i/o.  This didn't actually matter.

3f64564278 Fixed removal of devfs entries for the real slice corresponding to the
compatibility slice.  They were forgotten on last-close and then
creating them on first-open failed.

Devfs entries for slices other than the one containing the root file
system are still invisible unless you open a non-devfs inode on the
slice.

9c9137ea6c Three speed-ups in the output path (two small, one substantial):
1) Require all callers to pass a valid route pointer to ip_output()
   so that we don't have to check and allocate one off the stack
   as was done before.  This eliminates one test and some stack
    bloat from the common (UDP and TCP) case.

2) Perform the IP header checksum in-line if it's of the usual length.
    This results in about a 5% speed-up in my packet-generation test.

3) Use ip_vhl field rather than ip_v and ip_hl bitfields.

01a95d942e Don't use a newfangled auto initializer. Initialize everything by
assignment to avoid one bug and several pessimizations.

In the old version, gcc-2.6.3 (i386 version) generates 16 bytes
of static data and copies it using 4 4-byte load-stores.  gcc-2.7.2
generates 2 1-byte stores and calls memset() to zero 14 bytes.
Linking fails because memset() doesn't exist in the kernel.

In both versions, the 2 bytes stored directly are all that is
actually used unless the null padding at the end is used, since
the 3 4-byte words in the middle are initialized again by struct
assignment.  These words are misaligned.  gcc generates misaligned
load-stores for (small) misaligned struct copies.

Changed one instance of `const' similarly.  This is less like to be a

hack of #defining `const' as nothing gives harmless (?) null attributes
instead of syntax errors.

06fc5af99c When cslip gets an uncompressed packet, it attempts to save off the TCP/IP
header for use in decompressing subsequant packets. If cslip gets garbage
(such as what happens when there is a port speed mismatch or modem line
noise), it will occasionally mistake the packet as a valid uncompressed
packet. When it tries to save off the header, it doesn't bother to check
for the validity of the header length and will happily clobber not only
the cslip data structure, but parts of other kernel memory that happens
to follow it...causing, ahem, undesired behavior.

c80faa792c Work around a braindead signal handling in many newer HP printers.
They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt).  The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and
semi-polled mode instead of the fixed timeout with 1/2 s we've been
using previously (that caused the printer to run really slooow).

Printers that have been working previously should not be affected by
this.

088b8b1d26 Implement the SLIST and the STAILQ macros. This gives a program all the
aesthetics of using the 4.4 queue macros without paying undo space or time
in scenartios where a singly-linked list works fine.

From queue.h:
/*
 * A singly-linked list is headed by a single forward pointer. The elements
 * are singly linked for minimum space and pointer manipulation overhead at
 * the expense of O(n) removal for arbitrary elements. New elements can be
 * added to the list after an existing element or at the head of the list.
 * Elements being removed from the head of the list should use the explicit
 * macro for this purpose for optimum efficiency. A singly-linked list may
 * only be traversed in the forward direction.  Singly-linked lists are ideal
 * for applications with large datasets and few or no removals or for
 * implementing a LIFO queue.
 *
 * A singly-linked tail queue is headed by a pair of pointers, one to the
 * head of the list and the other to the tail of the list. The elements are
 * singly linked for minimum space and pointer manipulation overhead at the
 * expense of O(n) removal for arbitrary elements. New elements can be added
 * to the list after an existing element, at the head of the list, or at the
 * end of the list. Elements being removed from the head of the tail queue
 * should use the explicit macro for this purpose for optimum efficiency.
 * A singly-linked tail queue may only be traversed in the forward direction.
 * Singly-linked tail queues are ideal for applications with large datasets
 * and few or no removals or for implementing a FIFO queue.

6e9d1d8bb6 Fix support for the aic7850 by looking only at the relavent bits of the
QINCNT.  The 7850 puts random garbage in the high bits and all my attempts
to determine the cause of this failed.  This approach does seem to work
around the problem.

Go back to relying on the SCSIPERR interrupt instead of having the sequencer
interrupt at the beginning of ITloop after a parity error occured.

Determine the number of SCBs on a card automatically and base the qcntmask
on the number of SCBs.

Add entries for 11.4MHz, 8.8MHz, 8.0MHz, and 7.2MHz to ULTRA portion of
the syncrate table.  They seem to work fine on the 2940UW I have here and
will allow more non-ultra devices (like my tape drive) to run sync while
the adapter is in ULTRA mode.

Return XS_SELTIMEOUT instead of XS_TIMEOUT for selection timeouts.  I was
getting sick of waiting for the SCSI code to retry each non-existant unit
multiple times during boot and XS_SELTIMEOUT bypasses all retries.

Use new SLIST queue macros.  This was inspired by NetBSD using TAILQs in
their SCSI drivers.  For optimum cache hits, the free scb list should
be LIFO which is what the old and new code does.  NetBSD implemented a
FIFO queue for some reason.

    to determine the cause of this failed.  This approach does seem to work
    around the problem.

    Don't trust SCSIPERR to tell us when there is a parity error.  On
    some revs of the 7870 and the 7880, this bit follows the parity of
    the current byte.  Instead of using a SEQINT to tell the kernel,
    re-enable the standard parity error interrupt since it seems to pause
    the sequencer right at the time of the error which is the effect we were
    looking for anyway.

aic7xxx_reg.h:
    Remove PARITY_ERROR seqeuncer interrupt type, its no longer used.

2eb80d36fe Because of the way that ptrace() now calls procfs routines to read/write
the process's memory, it was possible for the procfs_domem() call to
return a residual leftover, but with no errno.  Since this is no good for
ptrace which ignored the the residual, remap a leftover amount into an
errno rather than fooling the caller into thinking it was successful when
in fact it was not.

Made the devfs `fd' devices bug for bug compatible with the ones created
by MAKEDEV:
- ownership is bin.bin, not root.wheel, except for std*.  The devfsext
  interface doesn't seem to allow specifying the ownership of /devfs/fd,
  so it's still incompatible.

a5e1a0f2e9 The recently introduced sv_sendsig entry of the sysentvec structure
is incorrectly set to 0, for the purpose of "ignoring" the signal.
This does not ignore the signal, but rather, executes the function
at location 0 in kernel mode, which shortly thereafter causes a panic.

The sv_sensig entry for ibcs2 emulation should be set to the system's
normal sendsig routine.

e73228724f Change how mirror writes are handled, according to the discussion on the
mailing list.

When initiating a write, ccdbuffer() returns two "struct ccdbuf *"s
linked together by the cb_mirror field.  "cb_pflags &
CCDPF_MIRROR_DONE" is set to 0 on both of them.

When a component returns to ccdiodone(), it checks if "cb_pflags &
CCDPF_MIRROR_DONE" is set or not.  If not, it sets the partner's
flag and returns.  If it is, it means its partner has already
returned, so it will go to the regular cleanup (which is in the
fallthrough code).

There should be no performance or functionality changes unless the
higher-level scsi driver does something with the resid value.  The change
is purely aesthetical and prepares us for the parity implementation.

233e8c18e8 A number of performance-reducing flaws fixed based on comments
from Larry Peterson &co. at Arizona:

- Header prediction for ACKs did not exclude Fast Retransmit/Recovery.
- srtt calculation tended to get ``stuck'' and could never decrease
  when below 8.  It still can't, but the scaling factors are adjusted
  so that this artifact does not cause as bad an effect on the RTO
  value as it used to.

The paper also points out the incr/8 error that has been long since fixed,
and the problems with ACKing frequency resulting from the use of options
which I suspect to be fixed already as well (as part of the T/TCP work).

f3a4ca94cd Add support for /very/ experimental -e (exposure) option.
Add support for LKM operation.

Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be
able to get ourselves a nice fat buffer from the kernel if we suspend.

Note: The LKM support looks kinda screwy in two areas, where I found
      problems with the kernel proper.  First, calling dev_attach()
      at module load time will cause a panic.  I haven't investigated.
      Secondly, I had to manually call qcam_drvinit() to register the
      device softc structure by hand at module load time.  This seems
      bogus,  it should be called as a core part of the module load
      process for character/block device drivers.

vm_offset_t is currently unsigned long but should probably be plain

to be unsigned long.
