f4f119017f Placed an #ifndef around RS_IBUFSIZE so that it can be changed in the
config file ... PR#528 is reportly fixed by adding 'options RS_IBUFSIZE=1024'

d3a3498598 Reinstitute the map lock for processes being swapped out. This
is needed because of the vm_fault used to bring the page table page
for the kernel stack (UPAGES) back in.  The consequence of the
previous incorrect change was a system hang.

1dce4e5d60 Add a lock for DMA Channels to prevent two devices from using the same DMA
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

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

    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.

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.

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).

Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be

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

fe63158271 Changes to the Digi/Arnet SYNC driver:
1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
   With this change the speed as tested with ttcp on a 2Mbit link went up
   from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
   return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.

(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
   are running at 2Mbit/s.

Did not accept changes to types of off_t and pid_t.  See
  <machine/ansi.h> for explanation.
Did not accept changes to major and minor macros upon bde's review.
  These changes are unnecessary.
Did not accept type change to fd_mask upon bde's review.
  This change is unnecessary as long as sizeof(fd_mask) divides FD_SETSIZE.
