270da41581 _pmap_unwire_pte_hold and pmap_remove_page:
Use pmap_TLB_invalidate instead of invltlb_1pg to eliminate
	unnecessary IPIs.

pmap_remove, pmap_protect and pmap_remove_pages:
	Use pmap_TLB_invalidate_all instead of invltlb to eliminate
	unnecessary IPIs.

pmap_copy:
	Use cpu_invltlb instead of invltlb when updating APTDpde.

pmap_changebit:
	Rather than deleting the unused "set bit" option (which may be
	useful later), make pmap_changebit an inline that is used
	by the new pmap_clearbit procedure.

Collectively, the first three changes reduce the number of TLB shootdown
IPIs by 1/3 for a kernel compile.

3c0d8bc982 Always create attach points for the various child busses that can be
attached to the nexus.  With one exception, this (for example) allows
you to do wierd things like kldload the eisa bus on the fly and then
drivers, and have it auto probe the eisa bus when the drivers come online.

The one exception being pci, it only adds the pcib after the presence of
the pci bus is detected and that's #if'ed code.

A side effect of this is that isa and eisa will be attached to the nexus
directly rather than the PCI->ISA or PCI->EISA bridges.  I'm not sure if
this is good or bad at this point, but it seems to be closer to the way
things are for the i386 family...  This is likely to be followed up.

This also fixes compilation without a PCI bus configured and will allow
eisa to work without PCI too.

0f6bc47029 Make the bt isa driver work..
- fix cut/paste problem. :-)
- don't forget to call isa_dmacascade()
- reset the port after we release resources.

That last one is a trap to watch out for..  The isa bus driver uses the
same port/irq/mem/etc variables for the initial probe hints as it does
for allocation/deallocation tracking.  Releasing a resource clears the
variable and then you loose the hint during attach.. (ouch!)

a49a3d4433 Implement an EISA new-bus framework. The old driver probe mechanism
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go.  The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa.  I have only tested the EISA part of this so far.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

e05da2e941 Made booting with -a work for all configurations. Previously it
only worked for configurations with "swap on generic".

usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
  warning about them.  They haven't done anything related to swap
  for almost 4 years, and were previously silently ignored,
  except for "swap on generic" which stopped swap${KERNEL}.c
  from being generated.  Code to support swapping is now deader
  than before.

usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.

sys/i386/conf/files.i386:
- swapgeneric.c is now standard.  It should be merged into autoconf.c
  so that it doesn't conflict with swap${KERNEL}.c for kernels named
  "generic".

sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots.  Since setroot() doesn't do anything
  harmful, this was just a waste of time, except possibly for booting with
  -a it may have helped prevent an undesireable call to setconf() by
  finding a bogus rootdev.
- honor -a for ffs roots.  -a now overrides all other ways of specifying
  the root device.  Previously, -r had precedence over -a, and the -a
  handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
  the way of a clean panic.

sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
  Don't decide things that are now decided in autoconf.c.  Code to
  support the "generic" case is now dead instead of useless.

173c0b9aba Search bdevsw[] instead of the half-baked builtin table of devices
in the RB_ASKNAME case.  I had thought that I made this change in
rev.1.18, but rev.1.18 only affects obscure subcases of the
RB_DFLTROOT case (subcases where the compiled in default root is
not found in bdevsw[] -- then the root device is set to the first
device in the half-baked table that is also in bdevsw[]).

Removed yet more vestiges of config-time swap configuration.

b9da114482 Build the functionality of the wdc_p hack into the ide_pci.c code.
All it did was match a specific device ID and turn on a quirk for
the wdc driver.

Incidently, at line 1462 there is a return that prevents the generic
ide_pci code from trying to look at the device.  I'd be interested
to know if we can take out the return and let the generic code "see" it.
I've left the return in because that's the way it worked before.

3e3e4375c8 Shoot the LKM support in the old wd/wdc/atapi driver set in the head and
perform a cleanup/unifdef sweep over it to tidy things up.  The atapi
code is permanently attached to the wd driver and is always probed.

I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.

Remember, this driver is destined to die some time.  It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.

ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.

2005b07aa8 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

3.  Config warns you if you don't use -s:

    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

d02c233129 Add driver support for gigabit ethernet adapters based on the Alteon
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.

Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).

I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.

55bfaed1c0 Fourth update to the new ATA/ATAPI driver:
Well, better late than newer, but things has been hectic
around here, sorry for the long delay.

DMA support has been added to the ATA disk driver.
This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers.
The promise support works without the BIOS on the board,
and timing modes are set to support up to UDMA speed. This
solves the problems with having more than one promise controller
in the same system.
There is support for "generic" DMA, that might work on other
controllers, but now you have been warned :)
More chipset specific code will come soon, I have to find testers
with the approbiate HW, more on that when I have it ready.

The system now uses its own major numbers, please run MAKEDEV
with the devices you need (ad?, acd?, afd?, ast?).
For now the disk driver will also attach to the old wd major
so one can at least boot without this step, but be warned, this
will eventually go away. The bootblocks will have to be changed
before one can boot directly from an "ad" device though.

Fixed problems:

    All known hang problems should be solved
	The probe code has been sligthly changed, this should solve
	the reports I have lying around (I hope).

    Hangs when accessing ata & atapi device on the same channel simultaniously.
	A real braino in ata_start caused this, fixed.

As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, agaiin you have been warned :)

But please tell me how it works for you!

Enjoy!

3aacd339f0 Fixed a couple of missing drive selects in wdreset(). This mainly
affects cases where there is a slave but no master.  These bugs
were usually recovered from provided ATAPI was configured, but only
after lengthy delays.  Configuring ATAPI still fixes some bugs for
non-atapi drives.

Don't wait for seek complete in wdreset().  If necessary for pre-ata
drives, it can be waited for later (we got it wrong by only looking
at it for drive 0 anyway).  It is set as part of a historical
signature for ata drives but doesn't say anything useful about the
reset state.  It is cleared as part of a non-historical signature
for atapi drives so that drivers which don't understand atapi drives
seem to see no drive.  Waiting for it caused lengthy delays and
broke the status returned by wdreset() in cases where the master
was not an ata drive.  Then the whole wdprobe() failed in some
cases where the recovery code didn't work.

Don't wait for drive ready in wdreset().  The considerations are
the same as for seek complete, except drive ready does say something
useful about the reset state of ata drives, and waiting for it
later is required anyway for such drives.

Lengthy delays can now be avoided by not configuring nonexistent
(ata) drives.  Unfortunately, this breaks detection of atapi drives
in some configurations.

8b89ef0a2d Finally!!
The much roumored replacement for our current IDE/ATA/ATAPI is
materialising in the CVS repositories around the globe.

So what does this bring us:

A new reengineered ATA/ATAPI subsystem, that tries to overcome
most of the deficiencies with the current drivers.

It supports PCI as well as ISA devices without all the hackery
in ide_pci.c to make PCI devices look like ISA counterparts.

It doesn't have the excessive wait problem on probe, in fact you
shouldn't notice any delay when your devices are getting probed.

Probing and attaching of devices are postponed until interrupts
are enabled (well almost, not finished yet for disks), making
things alot cleaner.

Improved performance, although DMA support is still WIP and not
in this pre alpha release, worldstone is faster with the new
driver compared to the old even with DMA.

So what does it take away:

There is NO support for old MFM/RLL/ESDI disks.
There is NO support for bad144, if your disk is bad, ditch it, it has
already outgrown its internal spare sectors, and is dying.

For you to try this out, you will have to modify your kernel config
file to use the "ata" controller instead of all wdc? entries.

example:

# for a PCI only system (most modern machines)
controller 	ata0
device		atadisk0	# ATA disks
device		atapicd0	# ATAPI CDROM's
device		atapist0	# ATAPI tapes

#You should add the following on ISA systems:
controller	ata1	at isa? port "IO_WD1" bio irq 14
controller	ata2	at isa? port "IO_WD2" bio irq 15

You can leave it all in there, the system knows how to manage.

For now this driver reuses the device entries from the old system
(that will probably change later), but remember that disks are
now numbered in the sequence they are found (like the SCSI system)
not as absolute positions as the old system.

Although I have tested this on all the systems I can get my hands on,
there might very well be gremlins in there, so use AT YOU OWN RISK!!
This is still WIP, so there are lots of rough edges and unfinished
things in there, and what I have in my lab might look very different
from whats in CVS at any given time. So please have all eventual
changes go through me, or chances are they just dissapears...

I would very much like to hear from you, both good and bad news
are very welcome.

Enjoy!!

e7ba67f274 Removed all traces of `p_switchtime'. The relevant timestamp is per-cpu,

It is now clear that the timestamp is always valid in fork_trampoline()
except when the child is running on a previously idle cpu, which
can only happen if there are multiple cpus, so don't check or set
the timestamp in fork_trampoline except in the (i386) SMP case.
Just remove the alpha code for setting it unconditionally, since
there is no SMP case for alpha and the code had rotted.

programs, including msdos, set PSL_NT in probes for old cpu types,

PSL_NT is even less useful in the signal handlers.  It just causes
T_TSSFLT faults on return from syscalls made by the handlers.
These faults are fixed up lazily so that Xsyscall() doesn't have
to be slowed down to prevent them.  The fault handler recently
started complaining about these faults occurring "with interrupts
disabled".  It should not have, but the complaints pointed to this
bug.

2a888f938e Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are
inserted.

This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed.  The devstat version number has been incremented as
well to reflect the change.

This sorts devices in the devstat list in "more interesting" to "less
interesting" order.  So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.

The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers.  For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.

Also, move the checkversion() call in vmstat(8) to a more logical place.

Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it.  Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.

faa273d5c2 Rip out PQ_ZERO queue. PQ_ZERO functionality is now combined in with
PQ_FREE.  There is little operational difference other then the kernel
    being a few kilobytes smaller and the code being more readable.

    * vm_page_select_free() has been *greatly* simplified.
    * The PQ_ZERO page queue and supporting structures have been removed
    * vm_page_zero_idle() revamped (see below)

    PG_ZERO setting and clearing has been migrated from vm_page_alloc()
    to vm_page_free[_zero]() and will eventually be guarenteed to remain
    tracked throughout a page's life ( if it isn't already ).

    When a page is freed, PG_ZERO pages are appended to the appropriate
    tailq in the PQ_FREE queue while non-PG_ZERO pages are prepended.
    When locating a new free page, PG_ZERO selection operates from within
    vm_page_list_find() ( get page from end of queue instead of beginning
    of queue ) and then only occurs in the nominal critical path case.  If
    the nominal case misses, both normal and zero-page allocation devolves
    into the same _vm_page_list_find() select code without any specific
    zero-page optimizations.

    Additionally, vm_page_zero_idle() has been revamped.  Hysteresis has been
    added and zero-page tracking adjusted to conform with the other changes.
    Currently hysteresis is set at 1/3 (lo) and 1/2 (hi) the number of free
    pages.  We may wish to increase both parameters as time permits.  The
    hysteresis is designed to avoid silly zeroing in borderline allocation/free
    situations.

47633640aa Change the load address of the ELF dynamic linker from "2L*MAXDSIZ"
to an architecture-specific value defined in <machine/elf.h>.  This
solves problems on large-memory systems that have a high value for
MAXDSIZ.

The load address is controlled by a new macro ELF_RTLD_ADDR(vmspace).
On the i386 it is hard-wired to 0x08000000, which is the standard
SVR4 location for the dynamic linker.

On the Alpha, the dynamic linker is loaded MAXDSIZ bytes beyond
the start of the program's data segment.  This is the same place
a userland mmap(0, ...) call would put it, so it ends up just below
all the shared libraries.  The rationale behind the calculation is
that it allows room for the data segment to grow to its maximum
possible size.

These changes have been tested on the i386 for several months
without problems.  They have been tested on the Alpha as well,
though not for nearly as long.  I would like to merge the changes
into 3.1 within a week if no problems have surfaced as a result of
them.

Didn't add an underscore to `svr4_esigcode' since it is correct for

was simpler and faster, and increasing the buffer size to support
1.5Mbps would cost about 1 US cent's worth of RAM per port, but I

27286ca9a8 Sun Bug ID 1251858 (on http://sunsolve1.sun.com) discusses the way that
Sun implemented iBCS2 compatibility on Solaris >= 2.6:  The emulator
runs in user-mode, patching the LDT so that client programs making
syscalls through the old iBCS2 call gate get handled by the emulator
process.  Unemulated syscalls therefore need their own call-gate that
bypasses the emulator.  Sun chose LDT entry 4 to implement this, which
is what we've been using as LUDATA_SEL, so we need to change LUDATA_SEL
if we want to run Solaris executables.

0a702d0a28 Patch from Soeren to remove inapropriate interrupt messages
also a bit of a BDE patch in there I beleive. Backs out a fix I needed for Cyrix support
early on but it turns out that a later fix in the cyrix support made it un-needed.

2907af2a96 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

88c5ea4574 Enable Linux threads support by default.
This takes the conditionals out of the code that has been tested by
various people for a while.
ps and friends (libkvm) will need a recompile as some proc structure
changes are made.

43482c407d Force the order of the setdefs* so that make -jN doesn't build the
setdefs* multiple times at the same time that it's compiling setdefs[0].c.
I think this was leading to unterminated linker sets etc.
