099a0e588c Bring in mbuma to replace mballoc.
mbuma is an Mbuf & Cluster allocator built on top of a number of
extensions to the UMA framework, all included herein.

Extensions to UMA worth noting:
  - Better layering between slab <-> zone caches; introduce
    Keg structure which splits off slab cache away from the
    zone structure and allows multiple zones to be stacked
    on top of a single Keg (single type of slab cache);
    perhaps we should look into defining a subset API on
    top of the Keg for special use by malloc(9),
    for example.
  - UMA_ZONE_REFCNT zones can now be added, and reference
    counters automagically allocated for them within the end
    of the associated slab structures.  uma_find_refcnt()
    does a kextract to fetch the slab struct reference from
    the underlying page, and lookup the corresponding refcnt.

mbuma things worth noting:
  - integrates mbuf & cluster allocations with extended UMA
    and provides caches for commonly-allocated items; defines
    several zones (two primary, one secondary) and two kegs.
  - change up certain code paths that always used to do:
    m_get() + m_clget() to instead just use m_getcl() and
    try to take advantage of the newly defined secondary
    Packet zone.
  - netstat(1) and systat(1) quickly hacked up to do basic
    stat reporting but additional stats work needs to be
    done once some other details within UMA have been taken
    care of and it becomes clearer to how stats will work
    within the modified framework.

From the user perspective, one implication is that the
NMBCLUSTERS compile-time option is no longer used.  The
maximum number of clusters is still capped off according
to maxusers, but it can be made unlimited by setting
the kern.ipc.nmbclusters boot-time tunable to zero.
Work should be done to write an appropriate sysctl
handler allowing dynamic tuning of kern.ipc.nmbclusters
at runtime.

Additional things worth noting/known issues (READ):
   - One report of 'ips' (ServeRAID) driver acting really
     slow in conjunction with mbuma.  Need more data.
     Latest report is that ips is equally sucking with
     and without mbuma.
   - Giant leak in NFS code sometimes occurs, can't
     reproduce but currently analyzing; brueffer is
     able to reproduce but THIS IS NOT an mbuma-specific
     problem and currently occurs even WITHOUT mbuma.
   - Issues in network locking: there is at least one
     code path in the rip code where one or more locks
     are acquired and we end up in m_prepend() with
     M_WAITOK, which causes WITNESS to whine from within
     UMA.  Current temporary solution: force all UMA
     allocations to be M_NOWAIT from within UMA for now
     to avoid deadlocks unless WITNESS is defined and we
     can determine with certainty that we're not holding
     any locks when we're M_WAITOK.
   - I've seen at least one weird socketbuffer empty-but-
     mbuf-still-attached panic.  I don't believe this
     to be related to mbuma but please keep your eyes
     open, turn on debugging, and capture crash dumps.

This change removes more code than it adds.

A paper is available detailing the change and considering
various performance issues, it was presented at BSDCan2004:

details, as well as credits.

662d471da6 Remove a broken micro-optimization from pmap_enter(). The ill effect
of this micro-optimization occurs when we call pmap_enter() to wire an
already mapped page.  Because of the micro-optimization, we fail to
mark the PTE as wired.  Later, on teardown of the address space,
pmap_remove_pages() destroys the PTE before vm_fault_unwire() has
unwired the page.  (pmap_remove_pages() is not supposed to destroy
wired PTEs.  They are destroyed by a later call to pmap_remove().)
Thus, the page becomes lost.

Note: The page is not lost if the application called munlock(2), only
if it relies on teardown of the address space to unwire its pages.

For the historically inclined, this bug was introduced by a
megacommit, revision 1.182, roughly six years ago.

026afdcc05 Quick fix for overflow when tsc_freq >= 2^31. "int profrate" in struct
gmon and struct gmonhdr was originally just to represent the kernel
(profiling) clock frequency and it remains poorly suited to representing
the frequencies of fast counters like the TSC.  It broke a year or two
ago.  This quick fix keeps it working for another year or month or two
until TSC frequencies can exceed 2^32, by dividing the frequency by 2.
Dividing the frequency by 4 would work for a little longer but would
lose a little too much precision.

30346936cf MFamd64:
Fixed profiling of trap, syscall and interrupt handlers and some
ordinary functions, essentially by backing out half of rev.1.106 of
i386/exception.s.  The handlers must be between certain labels for
the purposes of profiling, and this was broken by scattering them in
separately compiled .s files, especially for ordinary functions that
ended up between the labels.  Merge the files by #including them as
before, except with different pathnames and better comments and
organization.  Changes to the scattered files are minimal -- just
move the labels to the file that does the #includes.

This also partly fixes profiling of IPIs -- all IPI handlers are now
correctly classified as interrupt handlers, but many are still missing
mcount calls.

vm86bios.s is included as before, but it is now between the labels for
interrupt handlers again, which seems to be wrong since half of it is
for a non-interrupt handler.

e77c22bf45 Moved i386 asms to an i386 header. The asms are for calibration of
high resolution kernel profiling (options GUPROF.  "U" in GUPROF stands
for microseconds resolution, but the resolution is now smaller than 1
nanosecond on multi-GHz machines and the accuracy is heading towards
1 nanosecond too).  Arches that support GUPROF must now provide certain
macros for the calibration.  GUPROF is now only supported for i386's,
so the absence of the new macros for other arches doesn't break anything
that wasn't already broken.  amd64's have uncommitted support for
GUPROF, and sparc64's have support that seems to be complete except
here (there was an #error for non-i386 cases; now there are undefined
macros).

Changed the asms a little:
- declare them as __volatile.  They must not be moved, and exporting a
  label across asms is technically incorrect, so try harder to stop gcc
  moving them.
- don't put the non-clobbered register "bx" in the clobber list.  The
  clobber lists are still more conservative than necessary.
- drop the non-support for gcc-1.  It just gave a better error message,
  and this is not useful since compiling with gcc-1 would cause thousands
  of worse error messages.
- drop the support for aout.

eb8943b13e Rework the APIC mixed mode support a bit:
- Require the APIC enumerators to explicitly enable mixed mode by calling
  ioapic_enable_mixed_mode().  Calling this function tells the apic driver
  that the PC-AT 8259A PICs are present and routable through the first I/O
  APIC via an ExtINT pin.  The mptable enumerator always calls this
  function for now.  The MADT enumerator only enables mixed mode if the
  PC-AT compatability flag is set in the MADT header.
- Allow mixed mode to be enabled or disabled via a 'hw.apic.mixed_mode'
  tunable.  By default this tunable is set to 1 (true).  The kernel option
  NO_MIXED_MODE changes the default to 0 to preserve existing behavior, but
  adding 'hw.apic.mixed_mode=0' to loader.conf achieves the same effect.
- Only use mixed mode to route IRQ 0 if it is both enabled by the APIC
  enumerator and activated by the loader tunable.  Note that both
  conditions must be true, so if the APIC enumerator does not enable mixed
  mode, then you can't set the tunable to try to override the enumerator.

c2ce35977e - Change the APIC code to mostly use the recently added intr_trigger
and intr_polarity enums for passing around interrupt trigger modes and
  polarity rather than using the magic numbers 0 for level/low and 1 for

- Convert the mptable parsing code to use the new ELCR wrapper code rather
  than reading the ELCR directly.  Also, use the ELCR settings to control
  both the trigger and polarity of EISA IRQs instead of just the trigger
  mode.
- Rework the MADT's handling of the ACPI SCI again:
  - If no override entry for the SCI exists at all, use level/low trigger
    instead of the default edge/high used for ISA IRQs.
  - For the ACPI SCI, use level/low values for conforming trigger and
    polarity rather than the edge/high values we use for all other ISA
    IRQs.
  - Rework the tunables available to override the MADT.  The
    hw.acpi.force_sci_lo tunable is no longer supported.  Instead, there
    are now two tunables that can independently override the trigger mode
    and/or polarity of the SCI.  The hw.acpi.sci.trigger tunable can be
    set to either "edge" or "level", and the hw.acpi.sci.polarity tunable
    can be set to either "high" or "low".  To simulate hw.acpi.force_sci_lo,
    set hw.acpi.sci.trigger to "level" and hw.acpi.sci.polarity to "low".
    If you are having problems with ACPI either causing an interrupt storm
    or not working at all (e.g., the power button doesn't turn invoke a
    shutdown -p now), you can try tweaking these two tunables to find the
    combination that works.

7e4af296b3 - Add a member to the atpic interrupt source structures to indicate if the
IRQ is edge triggered or level triggered.  For ISA interrupts, we assume
  that edge triggered interrupts are always active high and that level
  triggered interrupts are always active low.
- Don't disable an edge triggered interrupt in the PIC.  This avoids
  outb instructions to the actual PIC for traditional ISA IRQs such as
  IRQ 1, 6, 14, and 15.  (Fast interrupts such as IRQs 0 and 8 don't mask
  their source, so this doesn't change anything for them.)
- For MCA systems we assume that all interrupts are level triggered and
  thus need masking.  Otherwise, we probe the ELCR.  If it exists we trust
  what it tells us regarding which interrupts are level triggered.  If it
  does not exist, we assume that IRQs 0, 1, 2, and 8 are edge triggered
  and that all other IRQs are level triggered and need masking.

030b156bf0 Add a simple mini-driver for the ELCR register. Originally, the ELCR
register controlled the trigger mode and polarity of EISA interrupts.
However, it appears that most (all?) PCI systems use the ELCR to manage
the trigger mode and polarity of ISA interrupts as well since ISA IRQs used
to route PCI interrupts need to be level triggered with active low
polarity.  We check to see if the ELCR exists by sanity checking the value
we get back ensuring that IRQS 0 (8254), 1 (atkbd), 2 (the link from the
slave PIC), and 8 (RTC) are all clear indicating edge trigger and active
high polarity.

This mini-driver will be used by the atpic driver to manage the trigger and
polarity of ISA IRQs.  Also, the mptable parsing code will use this mini
driver rather than examining the ELCR directly.

4f9e7c8b00 Use a private attach method for the MP Table host-PCI bridge driver rather

and the legacy_pcib_attach() function probes and parses the $PIR in
addition to adding the pci bus child device.

f203f177f4 Revert part of the "BIOS brain damage" from rev 1.10. It seems that
different BIOSs use the same exact settings to mean two very different and
incompatible things for the SCI.  Thus, if the SCI is remapped to a PCI
interrupt, we now trust the trigger/polarity that the MADT provides by
default.  However, the SCI can be forced to level/lo as 1.10 did by setting
the tunable "hw.acpi.force_sci_lo" to a non-zero value from the loader.

Thus, if rev 1.10 caused an interrupt storm, it should nwo fix your
machine.  If rev 1.10 fixed an interrupt storm on your machine, you
probably need to set the aforementioned tunable in /boot/loader.conf to
prevent the interrupt storm.

The more general problem of getting the SCI's trigger/polarity programmed
"correctly" (for some value of correctly meaning several workarounds for
broken BIOSs and inconsistent "implementations" of the ACPI standard) is
going to require more work, but this band-aid should improve the current
situation somewhat.

0287be96bf Add support for video output switching. It appears no systems use HCI to
change the video output but use a separate device with a DSSX method
and a HID of "TOS6201" instead.  We use a pseudo-driver to get the handle
for this object and pass it to the acpi_toshiba driver.

This is untested but seems to match the Linux Toshiba driver.

42d122e125 Converted the isa probe and attach to new-bus so that this driver works
without the (defunct) isa compatibility shims.  The new-bus-specific
parts are very similar to the ones for the pci probe and attach.

This was held up too long waiting for a repo copy to src/sys/dev/cy,
so I decided to fix the files in their old place.  This gives easier
to read and merge diffs anyway.

The "count" line in src/sys/conf/files won't be changed until after
the repo copy, so old kernel configs that specify a count need not be
(and must not be) changed until then.  The count is just ignored in
the driver.  One unfinished detail is dynamic allocation of arrays
with <count> and (<count> * 32) entries, and iteration over the arrays.
This is now kludged with a fixed count of 10 (up to 10 cards with up
to 32 ports each).
