bfe907886a Add a variable LOCAL_PREFIX that defaults to "/usr/local", as a
counterpart to X11BASE (default "/usr/X11R6").

Now PREFIX is set to ${X11BASE} or ${LOCAL_PREFIX} depending on
whether USE_IMAKE or USE_X11 is set or not.

This enables us to refer to non-X ports from X ports using
${LOCAL_PREFIX}, thus removing most of the remaining "/usr/local"s
from the ports tree.

This will also allow the system administrator to move the whole
"local" tree to somewhere else, without affecting X ports.  (Of course
not all ports are necessarily happy with that, but we're working on
it.)

Based on: an idea that came up while I was watching a football game
          several months ago ("hey, maybe I can move that sideline
          without disturbing the other!")

2d71a1f121 Another round of fixes:
. Replace my NIH-suffering code to detect the number of lines on
  the terminal by the curses variable LINES.

. Fix the selection code for countries with more than one screenful
  of locations.  The very few people living in America/US/Pacific
  now won't be charged for Indiana any longer... :)

. Removed the gross code that copied over the timezone file to
  /etc/localtime, and create a symlink now instead.

ef9805a3c8 Moved rtcin() to clock.c.
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable.  It only needs
to be fast in rtcintr().

4a775e8f68 Update the queue man page for the new SLIST and STAILQ macros. 1996-03-31 03:23:16 +00:00
Justin T. Gibbs
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.

ef6653eddb Implement the XS_SELTIMEOUT error code. This causes the SCSI code to
not retry again and should be used when a device times out during selection
(ie is not on the bus).  This should speed up the boot sequence.

09d0c1ca40 ncr.c:
Use new XS_SELTIMEOUT error code for selection timeouts.

aic7870.c:
   Move SCB walking code to aic7xxx.c and make it work for all card types.

   The flag AHC_EXTSCB is no longer needed since the SCBs are walked in
   all cases now.

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.

Spaces -> tabs.

b023c93005 Don't set the number of SCBs here. aic7xxx.c determines the number of

c2c5fd345d aic7xxx.seq:
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.

    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.

    Define QCOUNTMASK as the SRAM location for the mask to use on the
    QINCNT register.  QCOUNTMASK is determined by the number of SCBs
    supported by the device we're working on.

289ccde0bd Correct the handling of NOCLDSTOP when using sigvec()
Make the SA_NODEFER handling more correct, previously if you called
sigaction to set a handler and had SA_NODEFER set, and manually masked
the signal itself in sa_mask, and when you read the settings back later,
you'd find SA_NODEFER incorrectly cleared.

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.
