5b036e2b3c Fixed missing dependencies of genassym.o, gensetdefs.o and vers.o
on opt_global.h.  This actually matters for genassym.o (it depends
on at least SMP).

Don't undefine KERNEL for compiling genassym.c.  genassym.o really
depends on KERNEL, and the prototype mismatches that required
undefining KERNEL in rev.1.49 no longer exist.

Compile gensetdefs* with the same flags as genassym*.  External
`gen' programs such linux_genassym should also use these flags
(${GEN_CFLAGS}).

Fixed missing dependency generation for gensetdefs.o.  C sources
for external `gen' programs should be added to GEN_CFILES to get
their dependencies generated.

Cleaned up flags definitions and use.  All of ${CFLAGS} is now
passed to mkdep and the assembler (both are actually variants of
${CC} and will ignore the irrelevant flags).

a6796db6ce Ensure that the i8254 timecounter doesn't go backards. It sometimes
went backwards when interrupts were masked for more than one i8254
interrupt period.  It sometimes went backwards when the i8254 counter
was reprogrammed.  Neither of these should happen in normal operation.

Update the i8254 timecounter support variables atomically.  Calling
timecounter functions from fast interrupt handlers may actually work
in all cases now.

The VESA support code requires vm86 support. Make sure your kernel
configuration file has the following line.
        options "VM86"
If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
        options "VESA"

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600

The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.

vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'.  When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

===================================
                HARP  |  Host ATM Research Platform
                ===================================

                              HARP 3

What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols.  It is intended to
be a high-quality platform for IP/ATM research.

HARP provides a way for IP hosts to connect to ATM networks.  It supports
standard methods of communication using IP over ATM.  A host's standard IP
software sends and receives datagrams via a HARP ATM interface.  HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.

HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM.  HARP is
self-contained; it requires no other licenses or commercial software packages.

HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:

   o IETF ATMARP address resolution client
   o IETF ATMARP address resolution server
   o IETF SCSP/ATMARP server
   o UNI 3.1 and 3.0 signalling protocols
   o Fore Systems's SPANS signalling protocol

What's supported
----------------
The following are supported by HARP 3:

   o ATM Host Interfaces
        - FORE Systems, Inc. SBA-200 and SBA-200E ATM SBus Adapters
        - FORE Systems, Inc. PCA-200E ATM PCI Adapters
        - Efficient Networks, Inc. ENI-155p ATM PCI Adapters

   o ATM Signalling Protocols
        - The ATM Forum UNI 3.1 signalling protocol
        - The ATM Forum UNI 3.0 signalling protocol
        - The ATM Forum ILMI address registration
        - FORE Systems's proprietary SPANS signalling protocol
        - Permanent Virtual Channels (PVCs)

   o IETF "Classical IP and ARP over ATM" model
        - RFC 1483, "Multiprotocol Encapsulation over ATM Adaptation Layer 5"
        - RFC 1577, "Classical IP and ARP over ATM"
        - RFC 1626, "Default IP MTU for use over ATM AAL5"
        - RFC 1755, "ATM Signaling Support for IP over ATM"
        - RFC 2225, "Classical IP and ARP over ATM"
        - RFC 2334, "Server Cache Synchronization Protocol (SCSP)"
        - Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
                "A Distributed ATMARP Service Using SCSP"

   o ATM Sockets interface
        - The file atm-sockets.txt contains further information

What's not supported
--------------------
The following major features of the above list are not currently supported:

        o UNI point-to-multipoint support
        o Driver support for Traffic Control/Quality of Service
        o SPANS multicast and MPP support
        o SPANS signalling using Efficient adapters

This software was developed under the sponsorship of the Defense Advanced
Research Projects Agency (DARPA).

309290c72b This implements retrieving the contents of message buffer via sysctl(3)
as "machdep.msgbuf". It's needed in case of using stripped kernels, where
normal dmesg (which has to use kvm) doesn't work.

The buffer is unwound, meaning that the data will be linear, possibly
with some leading NULLs.

probably no less useful than dumping a.out-style core dumps as they

Note: I don't think that gcc should use getobjformat(), even though
it could.  The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

5d0c8abac1 Added Capture Area ioctl - BT848[SG]CAPAREA.
Normally the full 640x480 (768x576 PAL) image is grabbed. This ioctl
allows a smaller area  from anywhere within the video image to be
grabbed, eg a 400x300 image from (50,10).
See restrictions in BT848SCAPAREA.

2394cd9adb Initial support for using linux X servers under emulation - to use an
XFree86 server, users need to create the following links in their
/compat/linux/dev directory (assuming kernel configured with 4 VTs).

lrwxrwxrwx  1 root  wheel  7 Aug 30 22:59 tty0 -> console
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty1 -> ttyv0

lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty4 -> ttyv3

VT switching is still not yet supported. Attempting to switch VT
currently will cause Xserver bus error.

357f7eb6eb The aout->elf transition build from a 2.2.5/6/7 system requires that
a kernel be built and installed at just the right time. If the system
were to be rebooted after installing the 3.0 binaries without the
new kernel, the system is hosed.

The addition of this config file reserves the name of the config file
that the upgrade procedure uses. If an upgrade is to be performed on
a 2.2.5/6/7 system system for which a GENERIC kernel is inadequate,
this config file must be replace with a suitable one before performing
the upgrade.

On systems which report 'uname -r' as 3.0-CURRENT, the kernel build
is not performed and this file is ignored.

Add a sysctl 'machdep.cs_recv_delay' to specify how long to wait after

b63b587cb3 A better fix for kern/7144:
The check for dropping unicast packets not sent to our ethernet
address is after the bpf tap, but not conditioned on it.  All packets
received should get handed to bpf, and unicast packets not to us (mac)
should get dropped whether or not there is a bpf listener.  I believe
that the common optimization that the interface is in hw promisc mode
iff there is a bpf listener is in general wrong, but more frequently
so on wavelans.

I think Max's fix makes bpf listeners not see unicast packets sent to
others, but I'm not sure.

One can argue that checking on MOD_ENAL is wrong, but the code only
drops packets that shouldn't be received.  The correctness condition
is that it be run whenever unicast packets without our mac address can
be received.

ca0154bc75 Revamp the ELF include files to better support architecture-independent
applications.  Here's how it works.

The kernel should include <machine/elf.h> to get the definitions
for the native architecture.  It can reference the various ELF
structures with generic names like Elf_Sym, Elf_Shdr, etc.  A define
__ELF_WORD_SIZE is also available with the value 32 or 64 as
appropriate for the native architecture.

Generic applications should include <elf.h>, which is just a wrapper
for <machine/elf.h>.

Applications such as object file dumpers that need to deal with
foreign ELF files can include <sys/elf32.h> and/or <sys/elf64.h>.
Both can be included from the same source file if desired.  The
structure names must be referenced using wordsize-specific names
like Elf32_Sym, Elf64_Shdr, etc.

I haven't change the alpha stuff, but I haven't broken it either.

possible integral promotions, although this is too much work for
machine-dependent code.

vm code generally avoids warnings for pointer vs long size mismatches
by using vm_offset_t to represent pointers; pmap.c often uses plain
`unsigned int' instead of vm_offset_t and didn't use u_long elsewhere,

  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.

34e9dea435 Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICE
and DSO_NOLABELS flags prevent searching for slices and labels
respectively.  Current drivers don't set these flags.  When
DSO_NOLABELS is set, the in-core label for the whole disk is cloned
to create an in-core label for each slice.  This gives the correct
result (a good in-core label for the compatibility slice) if
DSO_ONESLICE is set or only one slice is found, but usually gives
broken labels otherwise, so DSO_ONESLICE should be set if DSO_NOLABELS
is set.

5c1a1eae83 Fixed error handling:
- Call isa_dmadone() whenever necessary to stop DMA and/or free bounce
  buffers.  Undead DMA corrupted the malloc freelist fairly consistently
  in the following configuration: SLICE kernel, 2 floppy drives, no disk
  in fd0, disk in fd1.
- Don't call fdc_reset() from fd_timeout().  Doing so gave an "extra"
  interrupt which was usually misinterpreted as being for completion
  of the next FDC command; the interrupt for completion of the next
  FDC command was then usually misinterpreted...  There were further
  complications for interrupts latched by the soft-spl mechanism so
  that they were delivered after all the h/w interrupts went away.
  This caused at least wrong head settle delays and may be why the
  FreeBSD floppy driver seems to munch floppies more than most floppy
  drivers.  The reset was unnecessary anyway in cases that didn't have
  the bug described next, since is was repeated a little later for
  the IOTIMEDOUT state.  The state machine has complications to handle
  resets correctly, so just use it.
- Don't call retrier() from fd_timeout().  The IOTIMEDOUT state needs
  to be processed next, and it isn't valid to set to that state if
  retrier() has aborted the current transfer.  Doing so caused null
  pointer panics after the previous bug was fixed.

Improved error handling:
- If an i/o is aborted, arrange to reset in the state machine before
  doing the next i/o.  New fdc flag for this.  This fixes spurious
  warnings and lengthy busy-waiting for the next i/o.
- Split STARTRECAL into RESETCOMPLETE and STARTRECAL and only check
  for the results from reset if we actually reset.  This fixes spurious
  warnings for other paths to STARTRECAL.  [Oops, it may break reset
  handling for motor-off resets.]

Cleanups in fd_timeout():
- Renamed to fd_iotimeout() to make it clearer that it is only used
  for i/o.
- Don't handle the bp == 0 case.  This case can't happen for i/o.
- Don't check for controller-busy.  We know it must be.
- Don't print anything.  retrier() already prints too much for normal
  errors.
- Fudge the state differently so that the state machine advances
  fdc->retry and the status is invalid (perhaps this should fudge a
  valid state like the one for WP).
- Style fixes.

e539380ea8 Set p->p_switchtime to switchtime instead of to the current time in
fork_trampoline() if switchtime is valid.  This fixes not accounting
for the time between the previous context switch and and the current
time (when the forked child starts up here) in most cases - the time
is now counted in the child's runtime.  I think it actually fixes
all cases, and switchtime is always valid here, since there must have
been a context switch just before the forked child starts up.  Some
code should be removed if this is correct.  The check that switchtime
is valid sometimes gives a false negative because the check isn't
correct until the after the first context switch after the system
has been up for >= 1 second.

e5d7d24361 Fixed error handling after a seek error that can't happen. When the
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case.  This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested.  The fix is simply to arrange to reset the state
machine.

Corruption of the buffer queue seems to only have been a problem in the
floppy driver.  Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order.  Dequeueing breaks it anyway.

cdevsw entries.  The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).

rawread()/rawwrite() went away as part of this though it's not strictly

ab48ff6913 Add workaround to allow the FreeBSD boot block to work on
Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'

This workaround has no effect on the boot sector code other than to

      Netboot compares the MAC address with 00:00:C0 to determine
      if it is a WD/SMC card, so it fails to detect these.

b)     Netboot is unable to boot kzipped kernels, as it assumes that
      the kernel load address is 0x100000.

c)     Users can abort the booting process and enter arbitrary network
      addresses, or boot from a floppy disk. This can be a problem when
      netbooted machines are used in a student environment.

d)     It is not possible to set all options via bootp. For example there
      is no way to remotely force a client to boot from disk. With both
      SECURE_BOOT(patch below) and NO_TFTP defined, short of unplugging
      the eprom there is no way at all to get the client to boot locally.
      A generic solution is to allow complete netboot commands to be sent
      using bootp lines such as:
	      :T132="diskboot":
e)     The last character of netboot command names is not checked. You
      can type 'iz 10.0.0.1' and it will be interpreted as 'ip'. This
      is only important if you try to add a new command which is the
      same as an existing one except for the last character.

f)     We have a configuration where multiple servers are willing to serve
      a diskless client. The tftp config file, or the bootptab entry on
      each server must specify the root and swap filesystems as 'ip:/fs'
      even though 'ip' will usually be the responding server's IP address.
      It would be nice if netboot could automatically prepend the server's
      IP address to an entry specified as just '/fs', so that multiple
      servers can use the same tftp or bootp configuration files. Admittedly
      this is hardly a major problem!
