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.

50ed7dfec0 INTR_TYPE_FAST / FAST_INTR interrupts (currently just serial interrupts)
have their own lock and do not need the MP lock.  The SMP cleanup was
    a little too conservative in MP locking fast interrupts but at least
    it's trivial to fix.  MFC soon.

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.

642ba07a24 If we are running in APIC_IO mode, pretend that we didn't see the BIOS
reporting an AT PIC.  We do this because otherwise the PIC will claim
IRQ 2 in an unshareable mode, preventing other devices from legitimately
using it.

For symmetry, in !APIC_IO mode, ignore the APIC if it's reported.

This is a hack; a better solution would have the PIC's driver release
the IRQ if it was not going to be active.

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

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.

12216bb553 Fix a long-standing bug which caused massive character loss in remote
serial gdb: interrupts were causing either overruns or stealing
characters.  Put splhigh() around the routines which transfer packets
across the line.  Since this happens when the system is halted in
debug, this doesn't cause any particular problem.  Now it is possible
to run the link at 115,200 bps.

c815a20cb2 Change our ELF binary branding to something more acceptable to the Binutils
maintainers.

After we established our branding method of writing upto 8 characters of
the OS name into the ELF header in the padding; the Binutils maintainers
and/or SCO (as USL) decided that instead the ELF header should grow two new
fields -- EI_OSABI and EI_ABIVERSION.  Each of these are an 8-bit unsigned
integer.  SCO has assigned official values for the EI_OSABI field.  In
addition to this, the Binutils maintainers and NetBSD decided that a better
ELF branding method was to include ABI information in a ".note" ELF
section.

With this set of changes, we will now create ELF binaries branded using
both "official" methods.  Due to the complexity of adding a section to a
binary, binaries branded with ``brandelf'' will only brand using the
EI_OSABI method.  Also due to the complexity of pulling a section out of an
ELF file vs. poking around in the ELF header, our image activator only
looks at the EI_OSABI header field.

Note that a new kernel can still properly load old binaries except for
Linux static binaries branded in our old method.

  *
  * For a short period of time, ``ld'' will also brand ELF binaries
  * using our old method.  This is so people can still use kernel.old
  * with a new world.  This support will be removed before 5.0-RELEASE,
  * and may not last anywhere upto the actual release.  My expiration
  * time for this is about 6mo.

used for ACLs, MAC labels, and Capabilities in the TrustedBSD

In this implementation, attributes are backed to data vnodes in the
style of the quota support in FFS.  Support for FFS extended
attributes may be enabled using the FFS_EXTATTR kernel option
(disabled by default).  Userland utilities and man pages will be
committed in the next batch.  VFS interfaces and man pages have
been in the repo since 4.0-RELEASE and are unchanged.

o ufs/ufs/extattr.h: UFS-specific extattr defines
o ufs/ufs/ufs_extattr.c: bulk of support routines

o coda/coda_vfsops.c: XXX required extattr.h due to ufsmount.h
(This should not be the case, and will be fixed in a future commit)

Currently attributes are not supported in MFS.  This will be fixed.

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.

B_WRITE was bogusly defined as zero giving rise to obvious coding

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.

80060e8897 Connect the ISA and PCI compatability shims to an option. In this case
it's options COMPAT_OLDISA and COMPAT_OLDPCI.  This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support.  I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.

prevent a page fault if the card is ejected while BPF is in use.  This

ejection.  Other drivers may also require this modification.

3346e881c1 - Add Support for the following PS/2 mice:
- Microsoft IntelliMouse Explorer: 2 buttons on top, 2 side buttons
    and a wheel which also acts as the middle button.  The mouse is
    recognized as "IntelliMouse Explorer".
  - Genius NetScroll Optical: 2 buttons on top, 2 side buttons and a
    wheel which also acts as the middle button.  The mouse is recognized
    as "NetMouse/NetScroll Optical".
  - MouseSystems SmartScroll Mouse (OEM from Genius?): 3 buttons on top,
    1 side button and a wheel.  The mouse is recognized as Genius
    "NetScroll".
  - IBM ScrollPoint: 2 buttons on top and a stick between the buttons.
    The stick can perform "horizontal scroll" in W*ndows environment.
    The horizontal movement of the stick is detected.  It is currently
    mapped to the Z axis movement in the same way as the first wheel.
    The mouse is recognized as "MouseMan+", as it is considered to be
    a variation of MouseMan.
  - A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement
    of the second wheel is reported as the Z axis movement in the
    same way as the first wheel. These mice are recognized as "4D
    Mouse" and "4D+ Mouse".
  - Tweak IntelliMouse support code a bit so that less-than-compatible
    wheel mice can work properly with the psm driver.
- Add driver configuration flags which correspond to the kernel
  options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't
  need to recompile the kernel when we need these functions.
- Properly keep track of the irq resource.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).

fixes some namespace pollution in general and breakage of modules that
aren't in the sys tree in particular (<machine/ipl.h> includes further
headers that aren't installed under /usr/include).

Reimplemented SPLASSERT() so that it is more machine independent and
less bloated and doesn't require the <machine/ipl.h> include spam.
In particular, don't assume that `cpl' can be printed using %08x
format.  The alpha arch doesn't even have `cpl'.  SPLASSERT() was
harmless on alphas because it isn't actually used.
