b3daa02e72 Yet another fix for configuration mechanism 1 register accesses:
Adjust the data port address by adding the two low order bits of
the register number. The address port takes only a word address
(i.e. ignores the two low order bits written to it).

694f6724f1 Changed inclusion of isa/icu.s to isa/ipl.s.
This is part of the breakup of UP/SMP specific INTerrupt code.

81c1993f87 Split vector.s into UP and SMP specific files:
- vector.s		<- stub called by i386/exception.s
 - icu_vector.s		<- UP
 - apic_vector.s	<- SMP

Split icu.s into UP and SMP specific files:
 - ipl.s		<- stub called by i386/exception.s (formerly icu.s)
 - icu_ipl.s		<- UP
 - apic_ipl.s		<- SMP

This was done in preparation for massive changes to the SMP INTerrupt
mechanisms.  More fine tuning, such as merging ipl.s into exception.s,
may be appropriate.

cd46d00ca6 This file has been made obsolete by the new PCI code. 1997-05-26 15:15:59 +00:00

5bec615793 Completely replace the PCI bus driver code to make it better reflect
reality. There will be a new call interface, but for now the file
pci_compat.c (which is to be deleted, after all drivers are converted)
provides an emulation of the old PCI bus driver functions. The only
change that might be visible to drivers is, that the type pcici_t
(which had been meant to be just a handle, whose exact definition
should not be relied on), has been converted into a pcicfgregs* .

The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t
and has been converted to just call the PCI drivers functions to access
configuration space register, instead of inventing its own ...

This code is by no means complete, but assumed to be fully operational,
and brings the official code base more in line with my development code.

A new generic device descriptor data type has to be agreed on. The PCI
code will then use that data type to provide new functionality:

1) userconfig support
2) "wired" PCI devices
3) conflicts checking against ISA/EISA
4) maps will depend on the command register enable bits
5) PCI to Anything bridges can be defined as devices,
   and are probed like any "standard" PCI device.

The following features are currently missing, but will be added back,
soon:

1) unknown device probe message
2) suppression of "mirrored" devices caused by ancient, broken chip-sets

This code relies on generic shared interrupt support just commited to
kern_intr.c (plus the modifications of isa.c and isa_device.h).

4c9340d45c Add support for shared interrupts to the kernel. This code is meant
be (eventually) architecture independent. It provides an emulation
of the ISA interrupt registration function register_intr(), but that
function does no longer manipulated the interrupt controller and
interrupt descriptor table, but calls the architecture dependent
function setup_icu() for that purpose.

After the ISA/EISA bus code has been modified to directly call the new
interrupt registartion functions (intr_create() and intr_connect()),
the emulation of register_intr() should be dropped.

The C level interrupt handler function should take a (void*) argument,
and the function pointer type (inthand2_t) should defined in some  other
place than isa_device.h.

This commit is a pre-requisite for the removal of the PCI specific shared
interrupt code.

1ffa54ef38 Added a test called 'LATE_START'.
This is now the default, it delays most of the MP startup to the function
machdep.c:cpu_startup().  It should be possible to move the 2 functions
found there (mp_start() & mp_announce()) even further down the path once
we know exactly where that should be...

e393b6503f One of the new cvs's features is to be able to run a checker on the
log messages after they've been entered.  This is more flexible than
using the editinfo script since it works for all log message types
and doesn't have to deal with trying to run the editor for the user.

The problem is that the verifymsg script can't modify the file like
editinfo can, which makes it useless for cleaning up the message (as is
needed for remote commits etc).  This change causes the verifymsg handler
to read back the message after the verify script has run and returned an
"OK" exit code.

6ed9fb2fc9 De-couple ppp from libalias. If libalias isn't there, the
alias commands simply won't work.  Only root may specify the
location of the alias lib (otherwise, it's hard-coded).

b2845e83db This commit adds support to ypbind(8) for binding to non-local servers.
The standard SunOS ypbind(8) (and, until now, the FreeBSD ypbind)
only selects servers based on whether or not they respond to clnt_broadcast().
Ypbind(8) broadcasts to the YPPROC_DOMAIN_NONACK procedure and waits
for answers; whichever server answers first is the one ypbind uses
for the local client binding.

This mechanism fails when binding across subnets is desired. In order
for a client on one subnet to bind to a server on another subnet, the
gateway(s) between the client and server must be configured to forward
broadcasts. If this is not possible, then a slave server must be
installed on the remote subnet. If this is also not possible, you
have to force the client to bind to the remote server with ypset(8).

Unfortunately, this last option is less than ideal. If the remote
server becomes unavailable, ypbind(8) will lose its binding and
revert to its broadcast-based search behavior. Even if there are
other servers available, or even if the original server comes back
up, ypbind(8) will not be able to create a new binding since all
the servers are on remote subnets where its broadcasts won't be heard.
If the administrator isn't around to run ypset(8) again, the system
is hosed.

In some Linux NIS implementations, there exists a yp.conf file where
you can explicitly specify a server address and avoid the use of
ypbind altogether. This is not desireable since it removes the
possibility of binding to an alternate server in the event that the
one specified in yp.conf crashes.

Some people have mentioned to me how they though the 'restricted mode'
operation (using the -S flag) could be used as a solution for this
problem since it allows one to specify a list of servers. In fact,
this is not the case: the -S flag just tells ypbind(8) that when it
listens for replies to its broadcasts, it should only honor them if
the replying hosts appear in the specified restricted list.

This behavior has now been changed. If you use the -m flag in conjunction
with the -S flag, ypbind(8) will use a 'many-cast' instead of a broadcast
for choosing a server. In many-cast mode, ypbind(8) will transmit directly
to the YPPROC_DOMAIN_NONACK procedure of all the servers specified in
the restricted mode list and then wait for a reply. As with the broadcast
method, whichever server from the list answers first is used for the
local binding. All other behavior is the same: ypbind(8) continues
to ping its bound server every 60 seconds to insure it's still alive
and will many-cast again if the server fails to respond. The code used
to achieve this is in yp_ping.c; it includes a couple of modified RPC
library routines.

Note that it is not possible to use this mechanism without using
the restricted list since we need to know the addresses of the available
NIS servers ahead of time in order to transmit to them.

45fedb144d Broke up parse_mp_table() into 2 passes:
- The 1st (preparse_mp_table()) counts the number of cpus, busses, etc. and
   records the LOCAL and IO APIC addresses.
 - The 2nd pass (parse_mp_table()) does the actual parsing of info and recording
   into the incore MP table.

This will allow us to defer the 2nd pass untill malloc() & private pages
are available (but thats for another day!).
