6c40705212 s/hint.acpi.0.disable/hint.acpi.0.disabled/
Fix device hints entry for disabling acpi(4).
This also should fix the arbitration with apm(4) when both drivers
are enabled.

Note that your /boot/device.hints needs to be updated if you want to
stop auto-loading acpi.ko or disable acpi(4).

cfd820d382 Fix a bug about the cooling system controlling in acpi_thermal driver.
Recent version of ACPI CA returns the package object which contains
object reference elements if the elements are named objects.
We need to be careful when you use acpi_ForeachPackageObject() in new
code...

2ccfc93222 Overhaul the ACPI PCI bridge driver a bit:
- Add an ACPI PCI-PCI bridge driver (the previous driver just handled
  Host-PCI bridges) that is a PCI driver that is a subclass of the generic
  PCI-PCI bridge driver.  It overrides probe, attach, read_ivar, and
  pci_route_interrupt.
  - The probe routine only succeeds if our parent is an ACPI PCI bus which
    we test for by seeing if we can read our ACPI_HANDLE as an ivar.
  - The attach routine saves a copy of our handle and calls the new
    acpi_pcib_attach_common() function described below.
  - The read_ivar routine handles normal PCI-PCI bridge ivars and adds an
    ivar to return the ACPI_HANDLE of the bus this bridge represents.
  - The route_interrupt routine fetches the _PRT (PCI Interrupt Routing
    Table) from the bridge device's softc and passes it off to
    acpi_pcib_route_interrupt() to route the interrupt.
- Split the old ACPI Host-PCI bridge driver into two pieces.  Part of
  the attach routine and most of the route_interrupt routine remain in
  acpi_pcib.c and are shared by both ACPI PCI bridge drivers.
  - The attach routine verifies the PCI bridge is present, reads in
    the _PRT for the bridge, and attaches the child PCI bus.
  - The route_interrupt routine uses the passed in _PRT to route a PCI
    interrupt.
  The rest of the driver is the ACPI Host-PCI bridge specific bits that
  live in acpi_pcib_acpi.c.
  - We no longer duplicate pcib_maxslots but use it directly.
  - The driver now uses the pcib devclass instead of its own devclass.
    This means that PCI busses are now only children of pcib devices.
  - Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar
    of the child bus.
  - Fetch the _PRT for routing PCI interrupts directly from our softc
    instead of walking the devclass to find ourself and then fetch our
    own softc.

With this change and the new ACPI PCI bus driver, ACPI can now properly
route interrupts for devices behind PCI-PCI bridges.  That is, the
Itanium2 with like 10 PCI busses can now boot ok and route all the PCI
interrupts.  Hopefully this will also fix problems people are having with
CardBus bridges behind PCI-PCI bridges not properly routing interrupts
when ACPI is used.

28bf1fad05 Add an ACPI PCI bus driver that is a subclass of the generic PCI bus
driver.  This driver overrides the probe, attach, and read_ivar methods.

If the parent bridge is an ACPI PCI bridge, then the probe routine will
match, otherwise it will fail.  It tests this by seeing if it can get
the ACPI_HANDLE ivar from the bridge device.

In the attach routine, it uses pci_add_children() to add all the child
devices (but with a slightly larger ivar so it can store ACPI_HANDLE's
for child devices) and then walks through the ACPI namespace below the
bus device to cache ACPI_HANDLE's for all child devices present in the
namespace.  It does this by comparing the pci slot and function to the
address encoded in _ADR of the devices in the ACPI namespace.

The read_ivar routine passes most requests off to pci_read_ivar()
and adds a new request so that the ACPI_HANDLE for a child device can
be read.

To add proper power support the power methods can be overridden as well,
but that is not currently implemented.  Also, there are cases where a
device may show in the ACPI namespace as a PCI device that the PCI probe
does not find.  Currently such devices are ignored.

473f1ca90d In acpi_pcib_route_interrupt(), the code claims to check to see if a PCI
LNK device (interrupt source provider sort of) is present before using it,
but the code actually tested the status (_STA) of the PCI bridge device
doing the routing, not the actual LNK device.  Fix it to check the status
of the LNK device.

d786139c76 Rework the kernel environment subsystem. We now convert the static
environment needed at boot time to a dynamic subsystem when VM is
up.  The dynamic kernel environment is protected by an sx lock.

This adds some new functions to manipulate the kernel environment :
freeenv(), setenv(), unsetenv() and testenv().  freeenv() has to be
called after every getenv() when you have finished using the string.
testenv() only tests if an environment variable is present, and
doesn't require a freeenv() call. setenv() and unsetenv() are self
explanatory.

The kenv(2) syscall exports these new functionalities to userland,
mainly for kenv(1).

116caf7cf7 Hide the ACPI counter probing printf behind bootverbose.
The conclusion is that this method really can tell the perfect from the
less than perfect ACPI counters.

It is in fact probably a bit more discriminative than that, but we
will rather condemn some otherwise perfect counters to the slightly
slower "-safe" version, than certify a counter as perfect which
will let us down later.

Many thanks to all the people who sent email reports!

This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.

 - move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
 - call power_profile_set_state() also from APM driver when AC-line
   status changes
 - add call-back function for Crusoe LongRun controlling on power
   profile changes for a example

cb877d0050 Add a new test_counter() function which tries to determine the width of
the inter-value histogram for 2000 samples.  If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method.

This method may be too strict, but the worst which can happen is that
we take the performance hit of the *_safe() method when we should not.

Make the *_safe() method more discriminating by mandating that the three
samples do not span more than 15 ticks on the counter.

Disable the PCI-ident based probing as a means to recognize good
counters.

d32e27a9f4 Tests by numerous people have shown that many chipsets do not properly

enough to adversely effect the timecounter code.

Default to the 'safe' version of the get-timecount function.  The probe
will override it if a known-good chipset is found.  This is temporary
until a more complete solution is found.
