4f76d87b21 Massive rewrite of pccard to convert it to newbus.
o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored.  This may change the units
  assigned to a card.  It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot.  we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
  allow it to attach.  See config files that were committed for examples
  on how to do this.

Drivers to be commited shortly.

This is an interrum fix until the new pccard.  ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.

I plan on doing minimal further work on this code base.  Be careful
when upgrading, since this code is known to work on my laptop and
those of a couple others as well, but your milage may vary.

BUGS TO BE FIXED:

o system memory isn't allocated yet, it will be soon.
o No devices actually have a pccard newbus attach in the tree.

BUGS THAT MIGHT BE FIXED:

o card removal, including suspend, usually hangs the system.

Many thanks to Peter Wemm and Doug Rabson for helping me to fill in
the missing bits of New Bus understanding at FreeBSD Con '99.

9782fb6209 Adjust the buffer cache to better handle small-memory machines. A
slightly older version of this code was tested by BDE and I.

    Also fixes a lockup situation when kva gets too fragmented.

    Remove the maxvmiobufspace variable and sysctl, they are no longer
    used.  Also cleanup (remove) #if 0 sections from prior commits.

    This code is more of a hack, but presumably the whole buffer cache
    implementation is going to be rewritten in the next year so it's no
    big deal.

d1eb1e4fa8 From: src/sys/i386/conf/PCCARD
revision 1.21
date: 1999/10/15 17:29:20;  author: imp;  state: Exp;  lines: +3 -3
Reorganize the attachement point for pcic (it was unattached and
floating before).  Attach pccard devices to pcic, one per slot
(although this may change to one per pcic).  pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet).  Move pccard compat code
into pccard/pccard_compat.c.

THIS REQUIRES A CONFIG FILE CHANGE.  You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller	pcic0	at isa?
controller	pcic1	at isa?
controller	card0

The old system was upside down and this corrects that problem.  It
will make it easier to add support for YENTA pccard/card bus bridges.

Much more cleanup needs to happen before newbus devices can have
pccard attachments.  My previous commit's comments were premature.

5a02dbe45a Fix the duplicate filenames that are the result of using getdents.
glibc2 defines struct dirent differently than the Linux kernel does.
The getdents function therefore needs to read a heuristically defined
number of kernel dirents to satisfy the request. In case where too
many kernel dirents have been read, the function lseeks on the
directory so that a next call will start with the right dirent. The
offset used in lseeking is the offset-field in the last dirent passed
to the application. This can only mean that the offset-field holds
the offset of the next dirent and not the offset of the dirent itself.

74121ffc35 Remove pccard attachment stub, this caused pccard unit 0 to be allocated
and unusable by the pccard system since pccard doesn't attach to the
nexus any more.  This was stopping my 3c589D from working as pccard unit
0 is used directly for resource allocation and this fails when unit 0
isn't actually attached to anything.

ed8c6514c4 Convert the mx driver to miibus.
In order to make this work, I created a pseudo-PHY driver to deal with
Macronix chips that use the built-in NWAY support and symbol mode port.
This is actually all of them, with the exception of the original MX98713
which presents its NWAY support via the MII serial interface.

The mxphy driver actually manipulates the controller registers directly
rather than using the miibus_readreg()/miibus_writereg() bus interface
since there are no MII registers to read. The mx driver itself pretends
that the NWAY interface is a PHY locayed at MII address 31 for the sole
purpose of allowing the mxphy_probe() routine to know when it needs to
attach to a host controller.

default. I have PnP changes in the wings for fdc, atkbd, psm, pcaudio, and

c5c6b7b38e Re-introduction of sigcontext.
struct sigcontext and ucontext_t/mcontext_t are defined in such
a way that both (ie struct sigcontext and ucontext_t) can be
passed on to sigreturn. The signal handler is still given a
ucontext_t for maximum flexibility.

For backward compatibility sigreturn restores the state for the
alternate signal stack from sigcontext.sc_onstack and not from
ucontext_t.uc_stack. A good way to determine which value the
application has set and thus which value to use, is still open
for discussion.

NOTE: This change should only affect those binaries that use
      sigcontext and/or ucontext_t. In the source tree itself
      this is only doscmd. Recompilation is required for those
      applications.

This commit also fixes a lot of style bugs without hopefully
adding new ones.

NOTE: struct sigaltstack.ss_size now has type size_t again. For
      some reason I changed that into unsigned int.

6a025a98a6 Turn off and remove the 'old' if_ep ISA/EISA/PCCARD driver.
Turn on the 'new' if_ep driver which supports:

	ISA		3c509
	MCA		3c529
	EISA		3c579
	PCCARD		3c589

I think all we're missing is support for the VME bus and S-100 bus
Etherlink III cards.

The new code has been tested by a number of people and all the important
bits work.  I've not been able to test the EISA code but will do so once
my hardware arrives.  Since I've changed nothing in the EISA code I suspect
it will perform the same manner as before.

Future changes involve whacking the ISA and PCCARD front ends to use
newbus and to convert the driver to bus_space and make it use ifmedia.

This is the first working network driver that supports MCA bus devices btw.

Enjoy.

956d3333ca sigset_t change (part 4 of 5)
-----------------------------

The compatibility code and/or emulators have been updated:

iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.

Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.

A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.

The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.

on the new siginfo_t and on ucontext_t instead of sigcontext, we
now need two version of sendsig and sigreturn.

A flag in struct proc determines whether the process expects an
old sigframe or a new sigframe. The signal trampoline handles
which sigreturn to call. It does this by testing for a magic
cookie in the frame.

The alpha uses osigreturn to implement longjmp. This means that
osigreturn is not only used for compatibility with existing
binaries. To handle the new sigset_t, setjmp saves it in
sc_reserved (see NOTE).

the struct sigframe has been moved from frame.h to sigframe.h
to handle the complex header dependencies that was caused by
the new sigframe.

NOTE: For the i386, the size of jmp_buf has been increased to hold
      the new sigset_t. On the alpha this has been prevented by
      using sc_reserved in sigcontext.

896f49b096 Newbusification of aha. dfr sent me the first cut, and I made it
work.  Be more verbose when one cannot allocate IRQ, et al since this
is a common configuration problem.  The cards have the IRQ soft wired
into their BIOS and do not try to do collision detection.  This can
cause problems when this IRQ is the same as another card/device.

The PNP hasn't been tested.  My PNP board is in a deployed system.
I'll sneak in testing of it sometime later.  I've been able to mount
the 3.3R cdrom that arrived today and access files off it.

13ccadd4b0 This is what was "fdfix2.patch," a fix for fd sharing. It's pretty
far-reaching in fd-land, so you'll want to consult the code for
changes.  The biggest change is that now, you don't use
	fp->f_ops->fo_foo(fp, bar)
but instead
	fo_foo(fp, bar),
which increments and decrements the fp refcount upon entry and exit.
Two new calls, fhold() and fdrop(), are provided.  Each does what it
seems like it should, and if fdrop() brings the refcount to zero, the
fd is freed as well.

e5a9fd5435 This commit adds driver support for PCI fast ethernet NICs based on
the Davicom DM9100 and DM9102 chipsets, including the Jaton Corporation
XPressNet. Datasheet is available from www.davicom8.com.

The DM910x chips are still more tulip clones. The API is reproduced
pretty faithfully, unfortunately the performance is pretty bad. The
transmitter seems to have a lot of problems DMAing multi-fragment
packets. The only way to make it work reliably is to coalesce transmitted
packets into a single contiguous buffer. The Linux driver (written by
Davicom) actually does something similar to this. I can't recomment this
NIC as anything more than a "connectivity solution."

This driver uses newbus and miibus and is supported on both i386
and alpha platforms.

SiS 900 and SiS 7016 PCI fast ethernet chipsets. Full manuals for the
SiS chips can be found at www.sis.com.tw.

This is a fairly simple chipset. The receiver uses a 128-bit multicast
hash table and single perfect entry for the station address. Transmit and
receive DMA and FIFO thresholds are easily tuneable. Documentation is
pretty decent and performance is not bad, even on my crufty 486. This
driver uses newbus and miibus and is supported on both the i386 and
alpha architectures.

7a2bb3b800 Some reorganization of sysarch() interface:
1. Move definitions of struct i386_*_args to the header file sysarch.h,
   since they are part of the sysarch API. struct i386_get_ldt_args and
   i386_set_ldt_args were identical, therefore make them into one
   struct i386_ldt_args. Libc should use these definitions as well.
2. Return a more sensible EOPNOTSUPP for unknown operations.

c6dfea0ebd Add sysctl variables for the Linuxulator. These reside under `compat.linux' as
discussed on current.

The following variables are defined (for now):

    osname (defaults to "Linux")
        Allow users to change the name of the OS as returned by uname(2),
        specially added for all those Linux Netscape users and statistics
        maniacs :-) We now have what we all wanted!

    osrelease (defaults to "2.2.5")
        Allow users to change the version of the OS as returned by uname(2).
        Since -current supports glibc2.1 now, change the default to 2.2.5
        (was 2.0.36).

    oss_version (defaults to 198144 [0x030600])
        This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I
        can commit now that we have the MIB. The default version number is the
        lowest version possible with the current 'encoding'.

A note about imprisoned processes (see jail(2)):
  These variables are copy-on-write (as suggested by phk). This means that
  imprisoned processes will use the system wide value unless it is written/set
  by the process. From that moment on, a copy local to the prison will be
  used.

A note about the implementation:
  I choose to add a single pointer to struct prison, because I didn't like the
  idea of changing struct prison every time I come up with a new variable. As
  a side effect, the extra storage is only needed when a variable is set from
  within the prison. This also minimizes kernel bloat when the Linuxulator is
  not used; both compiled in or as a module.

ca29e71c56 Take advantage of the apm/npx code and let them identify themselves rather
than having explicit hooks here.
Treat the eisa/isa attach a little differently so that we defer the
decision about to attach eisa/isa to the motherboard directly only if
the PCI probe (if it exists) fails to turn up a PCI->EISA/ISA bridge.
This restores the original device geometry where ISA and/or EISA attach
to their bridge rather than bypassing and going to the root.

f3b63bd388 Make the identify routine add itself with priority 100 to make sure it
goes after the npx/apm devices and any other motherboard devices that
may get added down the track.

da4113b31f Add an identify method to allow npx to arrange itself to be attached to
the nexus without explicit code in the nexus to do so.

7fa76d3a80 Add an identify method to allow apm to attach itself to the nexus
without hooks in there.

cd8fd32d0d make pnp.h self contained, for what good it'll do since it's days are
numbered (new pnp-aware isa code in the pipeline).

49d3a95692 Fix `key release event prevent suspend' problem. We don't need
`sleep 1; zzz' trick now.

- APM BIOS Call for suspend/standby now should be issued with delay.
- Delay for suspend/standby can be adjusted by using sysctl(8) interface
  (eg. sysctl -w machdep.apm_suspend_delay=3).

e7dcbbe297 Make "s_unlock" an inline function. (Inlining this function takes
less space than calling it.  A callable version still exists for
use by some assembly code.)
