d51afe9d38 added support for link, and remove (unlink)
can now ln /devs/disks/floppy/fd1.1200 to fd1
and remove unwanted dirs and devices etc.
Still has a fatal bug.. don't use yet :)

a3adc4f8c5 Revert most changes of previous commit.
Changes relative to 1.12:
- Put extra instruction between outl()/inl() sequence to prevent the
  old value being read back because of the bus capacitance.
- Additional check for existence of register at CONF2_ENABLE_PORT.

c87ad37e61 Check the return value from vm_map_pageable() when mapping the process's
UPAGES and associated page table page. Panic on error. This is less than
optimial and will be fixed in the future, but is better than the old
behavior of panicing with a "kernel page directory invalid" in pmap_enter.

0b4a1769be Our existing Cyrix cache-disable code was short-cutting the steps for
setting the control register.  Make the read and write operations two
completely separate steps.

While we're at it, pull in the whole set of Cyrix cache control options
from NetBSD-current,  since a few motherboards do the right thing with
the Cyrix chip.

There is no option to disable the internal cache completely (yet).

97e112628f Check for page being resident when doing I/O with /dev/kmem and return
EFAULT if it is not resident. This prevents the system from manufacturing
a zero-fill page for unused but allocated areas of the kernel's VM. This
should fix the "CMAP busy" panic that some people saw during system
startup.

0937c08c4e 1) Killed 'BSDVM_COMPAT'.
2) Killed i386pagesperpage as it is not used by anything.
3) Fixed benign miscalculations in pmap_bootstrap().
4) Moved allocation of ISA DMA memory to machdep.c.
5) Removed bogus vm_map_find()'s in pmap_init() - the entire range was
   already allocated kmem_init().
6) Added some comments.

virual_avail is still miscalculated NKPT*NBPG too large, but in order to
fix this properly requires moving the variable initialization into locore.s.

832e06d4dc From Bruce Evans: (prototype related changes, other cleanups)
Add prototypes.  Use static for function definitions to match existing
prototypes.  Otherwise leave functions that should be static as extern.
TODO: declare everthing except sidriver and siintr as static.  I use
some new cdevs registration functions to do this for syscons and pcvt.

Fix siintr() to match its prototype in ioconf.c (don't return anything).
This may break the eisa support, but Julian says that eisa interrupts
never worked anyway.

(EISA support was never tested anyway - Peter)

a89f7290be Increased SOMAXCONN from 5 to 32. 5 was too small a value for just about
any reasonably busy machine, and by any measure is a lousy "max" value.
32 was chosen after a careful analysis of typical listen queue depths
on several busy Internet servers (both web and ftp). I also intend to
add a statistics counter for dropped connection requests due to the limit
being exceeded.

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.

f2cb5630d0 cons.c:
Split off cdevsw initialization in cninit() into a new function
cninit_finish() that isn't called until all hardware device drivers
have been attached.  The bdevsw entry of the driver for the physical
console needs to be hooked after the physical driver has been
attached in case the attachment modified the entry.

Rearrange cninit() to avoid changing cn_tab until the driver for the
physical console has been initialized, so that the previous driver
(if any) can be used for debugging.

Start removing half-baked lint support.  bdevsw functions usually have
unused args but /*ARGSUSED*/ was used for only about 5% of them.

cons.h:
Declare cn_init_finish().

autoconf.c:
Call cn_init_finish().

Start adding prototypes.  Functions with bogus linkage (extern where
static is probably should be static) are explicitly declared as extern
so that the can be found easily (extern in a non-header is usually
wrong).

All:
Continue cleaning up init stuff: init functions shall be static;
INITs should be at the start of files...

6b435e575c Call output process in slstart() whether or not there is any output. As
in pppstart(), the output process may be overloaded to handle hardware
flow control and hardware output completions.

Don't wait for output to drain in slclose().  Discard output immediately.
New output is not prevented while processes are waiting for output to
drain (this is a bug), so the wait was sometimes forever.  Infinite
waits are also possible when CCTS_OFLOW is enabled and CTS is down.
Infinite waits were also caused by the above bug in slstart().

Start changing new init stuff yet again: rename unused arg `dummy'.

spending too much time on the vnode confusion

2bf07b2bd7 Patch to the atapi driver, by Serge V.Vakulenko, minor changes
by me...

Original message:

This patch upgrades the ATAPI CD-ROM driver to version 1.3.

It has three bugs fixed:

1) The `controller not ready' message at startup and later.
   It was caused by staled media change bit.

2) Incorrect shuffling of model string for some drives (NEC, Mitsumi).

3) Handling of drives which report itself as been of direct-access type,
   instead of CD-ROM type.

There is one known bug which is not fixed yet -- probing
in absense of IDE disks. A work-around exists though (thanks Steve!).
If you have no IDE disks attached, then remove them from the kernel
config file to make the CD-ROM attach correctly.
Unfortunately, there is no way to disable them from the kernel
interactive config mode.
