f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

65cbb03cfe Added new options CPU_PPRO2CELERON and CPU_L2_LATENCY to support
Socket 8 to 370 converters.  When (1) CPU_PPRO2CELERON option is
defined, (2) Intel CPU is found and (3) CPU ID is 0x66?, L2 cache is
enabled through MSR 0x11e.  The L2 cache latency value can be
specified by CPU_L2_LATENCY option.  Default value of L2 cache latency
is 5.

These options are useful if you use Socket 8 to Socket 370 converter
(e.g. Power Leap's PL-Pro/II.)  Most PentiumPro BIOSs don't enable L2
cache of Mendocino Celeron CPUs because they don't know Celeron CPUs.
These options are needles if you use a Coppermine (FCPGA) Celeron or
PentiumIII, becuase the L2 cache enable bit is hard wired and L2 cache
is always enabled.

129e169651 Always include the full symbol table (as specified by its start and
end values in bootinfo) in kernel space if it is loaded (i.e., if its
specified end address is nonzero), not just if it is loaded and DDB
is configured.  This may be used to fix kldsym(2) for booting without
/dev/loader; currently, in this case, it just fixes unused pointers
and wastes space consistently.  For booting in the normal way with
/boot/loader, the table is included and pointed to in a different way
and kldsym(2) works.

c3c50c4e3a Further fixes for multiple-IO-APIC systems from Tor Egge:
Further experimentation showed that some Dell 2450 machines with the
prevention kludge installed still got T_RESERVED traps.  CPU interrupt
vector 0x7A was observed to be triggered.  This might have been the
bitwise OR of two different vectors sent from each of the IOAPICs at
the same time.

	IOAPIC #0: 0x68 --> irq 8: RTC timer interrupt
	IOAPIC #1: 0x32 --> irq 18: scsi host adapter or network interface
		   ----
		   0x7a --> T_RESERVED

Both IOAPICs had ID 0.

Appendix B.3 in the MP spec indicates that the operating system is
responsible for assigning unique IDs to the IOAPICs.

The enclosed patch programs the IOAPIC IDs according to the IOAPIC
entries in the MP table.

8b03c8ed5e This is a cleanup patch to Peter's new OBJT_PHYS VM object type
and sysv shared memory support for it.  It implements a new
    PG_UNMANAGED flag that has slightly different characteristics
    from PG_FICTICIOUS.

    A new sysctl, kern.ipc.shm_use_phys has been added to enable the
    use of physically-backed sysv shared memory rather then swap-backed.
    Physically backed shm segments are not tracked with PV entries,
    allowing programs which use a large shm segment as a rendezvous
    point to operate without eating an insane amount of KVM in the
    PV entry management.  Read: Oracle.

    Peter's OBJT_PHYS object will also allow us to eventually implement
    page-table sharing and/or 4MB physical page support for such segments.
    We're half way there.

0385347c1a Implement an optimization of the VM<->pmap API. Pass vm_page_t's directly
to various pmap_*() functions instead of looking up the physical address
and passing that.  In many cases, the first thing the pmap code was doing
was going to a lot of trouble to get back the original vm_page_t, or
it's shadow pv_table entry.

Inspired by: John Dyson's 1998 patches.

Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t.  This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system.  (8 bytes on the Alpha).

Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc).  Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries.  This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).

Add a function to add a new page to the freelist.  This could be used
for reclaiming the previously wasted pages left over from preloaded
loader(8) files.

558d6032c2 Turn on USB support for most USB devices. udbp is not turned on since
NETGRAPH is not present in GENERIC at the moment.  Also, change some
settings to support USB installs:

- Add KBD_INSTALL_CDEV as an option to make /dev/kbd[01] actually work.
- Turn on keyboard probing in sc0.  The syscons driver will now use a
  flag documented in ukbd(4) but not in sc(4) that tells syscons to
  actively search for a keyboard device if none is found.  This allows
  USB keyboards to just be plugged in and instantly start working.
- Require the atkbd0 driver to actually probe to see if a keyboard is
  there.  This allows USB keyboards to be seen by sc0 if an AT keyboard
  isn't plugged into the computer.  This also means that you will no
  longer be able to plug an AT keyboard into a machine after it has
  booted a GENERIC kernel and use it.  AT keyboards aren't designed for
  this anyway.  USB keyboards are designed for this, and they work.

b5ea1f0c77 The USB double bulk pipe driver (Host to host cables). Currently there
are two supported chips, the NetChip 1080 (only prototypes available)
and the EzLink cable. Any other cable should be supported however as they
are all very much alike (there is a difference between them wrt
performance).

It uses Netgraph.

This driver was mostly written by Doug Ambrisko and Julian Elischer and
I would like to thank Whistle for yet another contribution. And my
aplogies to them for me sitting on the driver for so long (2 months).

Also, many thanks to Reid Augustin from NetChip for providing me with a
prototype of their 1080 chip.

Be aware of the fact that this driver is very immature and has only been
tested very lightly. If someone feels like learning about Netgraph however
this is an excellent driver to start playing with.

300451c472 Some more i386-only BIOS-friendliness:
- Add support for using the PCI BIOS functions for configuration space
   accesses, and make this the default.

 - Make PNPBIOS the default (obsoletes the PNPBIOS config option).

 - Add two new boot-time tunables to disable each of the above.

255108f385 Make sysv-style shared memory tuneable params fully runtime adjustable

Also move SHMMAXPGS from $machine/include/vmparam.h as the comments that
went with it were wrong... we don't allocate KVM space for the pages so
that comment is bogus..  The only practical limit is how much physical
ram you want to lock up as this stuff isn't paged out or swap backed.

includes one of bus_at386.h and bus_pc98.h. Becuase only bus_pc98.h
supports indirect pio and bus_at386.h is identical to old bus.h, there
is no functional change in PC-AT's kernels.  That is, it cannot cause
performance loss.

36e9f877df Commit major SMP cleanups and move the BGL (big giant lock) in the
syscall path inward.  A system call may select whether it needs the MP
    lock or not (the default being that it does need it).

    A great deal of conditional SMP code for various deadended experiments
    has been removed.  'cil' and 'cml' have been removed entirely, and the
    locking around the cpl has been removed.  The conditional
    separately-locked fast-interrupt code has been removed, meaning that
    interrupts must hold the CPL now (but they pretty much had to anyway).
    Another reason for doing this is that the original separate-lock for
    interrupts just doesn't apply to the interrupt thread mechanism being
    contemplated.

    Modifications to the cpl may now ONLY occur while holding the MP
    lock.  For example, if an otherwise MP safe syscall needs to mess with
    the cpl, it must hold the MP lock for the duration and must (as usual)
    save/restore the cpl in a nested fashion.

    This is precursor work for the real meat coming later: avoiding having
    to hold the MP lock for common syscalls and I/O's and interrupt threads.
    It is expected that the spl mechanisms and new interrupt threading
    mechanisms will be able to run in tandem, allowing a slow piecemeal
    transition to occur.

    This patch should result in a moderate performance improvement due to
    the considerable amount of code that has been removed from the critical
    path, especially the simplification of the spl*() calls.  The real
    performance gains will come later.

7c58e473f5 Commit the buffer cache cleanup patch to 4.x and 5.x. This patch fixes a
fragmentation problem due to geteblk() reserving too much space for the
    buffer and imposes a larger granularity (16K) on KVA reservations for
    the buffer cache to avoid fragmentation issues.  The buffer cache size
    calculations have been redone to simplify them (fewer defines, better
    comments, less chance of running out of KVA).

    The geteblk() fix solves a performance problem that DG was able reproduce.

    This patch does not completely fix the KVA fragmentation problems, but
    it goes a long way

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

A lot of this patch were machine generated (Thanks to style(9) compliance!)
