da72d149ef Don't attach special devices in the order they appear in the AML tree.
If the embedded controller exists before the sysresource devices, for
example, it will be attached first.  Instead, let the normal device
order function work as we first desired. [1]

There still remained a problem where we couldn't allocate resources in
acpi0 that were passed up by the sysresource pseudo-devices.  These
devices had to probe/attach first to give their resources to acpi, then
acpi would allocate them before probing/attaching other devices.  To
work around this, we attach them from acpi_sysres_alloc().  A better
approach would be to implement multi-pass probe/attach in newbus but
that's a much bigger task.

3a6497c102 *sigh* Revert stuff that wasn't supposed to be committed. The
acpi_resource change was a minor nit offered as an early candidate for
the recent ACPICA import problem and the acpi.c change is one I need to
test still that makes the ordered probing of system devices actually work
as advertised (probe devices in order based on the type of device rather
than in the order we encounter them in the device tree).

f25bdd3bb3 Work around at least one busted BIOS. If we get a source index in a _PRT
entry that is not zero, assume that it is really a hard-wired IRQ (commonly
used for APIC routing) and not a source index.  In practice, we've only
ever seen source indices of 0 for legitimate non-hard-wired _PRT entries.

b0977ecfd7 Don't create new-bus resources for ACPI extended IRQ resources that are
producers rather than consumers as new-bus resources only handle consumed
resources.  We already do this for the other ACPI resource types that
support the producer/consumer attribute.

adad474471 Rework sysresource management. Instead of having each sysresource object
hold its own values, pass them up to the parent (acpi0) and merge/uniq them
on the way.  After the namespace evaluation, acpi will reserve these
resources and manage them via rman before bus_generic_probe() and
bus_generic_attach().  This is necessary because some systems specify
conflicting resources in separate sysresource objects.  It's also cleaner
in that the interface between sysresource and acpi is now merely the parent's
resource list.  This code handles the following cases:

1. Unique resource:  add it to the parent via bus_set_resource().
2. New wholly contained in old:  discard new.
3. New tail overlaps old head:  grow old head downward.
   AND/OR
4. New head overlaps old tail:  grow old tail upward.

d22e9c6e0d Correctly handle BIOS resources that are duplicated (!). There are many
systems that have overlapping regions specified in their sysresource
objects.  This patch fixes ATA DMA and acpi_timer allocation for such
sysctems.  It should eventually be moved to resource_list_add() if it is
a valid generalized approach.  The minimal approach for 5.3 is:

"Loop through all current resources to see if the new one overlaps
any existing ones.  If so, the old one always takes precedence and
the new one is adjusted (or rejected).  We check for three cases:

1. Tail of new resource overlaps head of old resource:  truncate the
   new resource so it is contiguous with the start of the old.
2. New resource wholly contained within the old resource:  error.
3. Head of new resource overlaps tail of old resource:  truncate the
   new resource so it is contiguous, following the old."

95957f6256 - Defer BUS_CONFIG_INTR() on ACPI IRQ resources until the resources are
actually used.  For most ACPI devices this means deferring the call
  until bus_alloc_resource().
  - Add a function acpi_config_intr() to call BUS_CONFIG_INTR() for an
    ACPI IRQ resource using the trigger mode and polarity information
    stored in the ACPI resource object.
  - Add a function acpi_lookup_irq_resource() to lookup the ACPI IRQ
    resource that corresponds to a specified rid and new-bus resource.
  - Have the ACPI PCI bridge driver call BUS_CONFIG_INTR() on interrupts
    that it routes through link devices.
- Remove needactivate variable from acpi_alloc_resource() by changing the
  function not modify the flags variable but just mask off RF_ACTIVE when
  calling rman_reserve_resource().

9123341378 Add support to ACPI to manage its own resources. Previously, resource
allocation was passed up to nexus.  Now, we probe sysresource objects and
manage the resources they describe in a local rman pool.  This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads.  The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman.  Sysresource objects add their resources to
the pool and reserve them upon boot.  This means sysresources need to be
probed before other ACPI devices.

Changes include:
* Add ordering to the child device probe.  The current order is:  system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.

24752c4291 Extend the ACPI resource handling to make use of the BUS_CONFIG_INTR()
method. This is necessary on ia64 where it's known that serial interfaces
described in the ACPI namespace may not have the well-known IRQs assigned
to them. This confuses us in thinking they are PCI based interrupts and
wrongly program the APIC.

991fcff585 Fix a De Morgan bug: If we only expect a memory range OR an
I/O port range, then we should ignore a resource if it's NOT
a memory range AND NOT an I/O port range.
The OR in the condition caused us to ignore perfectly valid

832183ba00 Retarget the resource parser slightly. We only fetch current resources
for the device now (we should really just be parsing a passed-in resource
buffer).

Wrap long lines so this is (more) readable.

Support Address16 and Address32 resources, in the CONSUMER case.

Support DRQs so that we can handle ISA devices.

Support ExtendedIrqs (we ignore most of their attributes)

Add a placeholder device for system memory and system resources.  This
takes the place of the nexus placeholder, which only attaches to ISA.

0ae554237c - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.
