97d31723e7 Make a pass through all drivers checking specs for desired behavior on
SMP systems.  It appears all drivers except ichss should attach to each
CPU and that settings should be performed on each CPU.  Add comments about
this.  Also, add a guard for p4tcc's identify method being called more than
once.

373dd87688 - Add a new quirk to indicate that pin 0 of the first I/O APIC is really
IRQ 0 and not an ExtINT pin.  The MADT enumerators ignore the PC-AT flag
  and ignore overrides that map IRQ 0 to pin 2 when this quirk is present.
- Add a block comment above the quirks to document each quirk so that we
  can use more verbose descriptions quirks.

0db8fa8984 Increase the maximum to wait for a transition from 1 to 10 ms. In some
modes, systems may take longer.  If the status values don't match, try
matching just the lowest 8 bits if no bits above 8 are set in the desired
value.  The IBM R32 has other bits set in the status register that are
irrelevant to the expected value.

a1adf35e65 Set the start of the cooling time later on, when we're actually performing
the switch.  Other interim tests (i.e., for minimum runtime) could
invalidate the start time.  This fixes transitions to cooler states in that
now they go to the next active state (_AC0 -> _AC1) instead of going
straight to off (_AC0 -> off).

e94a0c1a18 Introduce a new method, cpufreq_drv_type(), that returns the type of the
driver.  This used to be handled by cpufreq_drv_settings() but it's
useful to get the type/flags separately from getting the settings.
(For example, you don't have to pass an array of cf_setting just to find
the driver type.)

Use this new method in our in-tree drivers to detect reliably if acpi_perf
is present and owns the hardware.  This simplifies logic in drivers as well
as fixing a bug introduced in my last commit where too many drivers attached.

e22cd41c01 Add support for the CPUFREQ_FLAG_INFO_ONLY flag. Devices that report this
are not added to the list(s) of available settings.  However, other drivers
can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to
get info about available settings.

Update the acpi_perf(4) driver to use this flag in the presence of

themselves.

this value controls Px states, not throttling as the comment said.  Since
we didn't support Px states before, there was no impact.  Also, note that
we delay the write to SMI_CMD until after booting is complete since it
sometimes triggers a change in the frequency and we want to have all

94b3af82c1 - Add support for link devices where _CRS just outright fails to execute.
For such devices, we require _PRS to exist and we warn if any of the
  resources in _PRS are not IRQ resources (since we'll have no way of knowing
  which of those resources to use without a working _CRS).  When it does
  come time to set resources, we build up a resource buffer from scratch
  as we do for devices with _CRS that only have IRQ resources.
- Fix a bug with setting extended IRQ resources where we set the IRQ value
  in the wrong resource structure meaning that whichever IRQ was listed in
  _PRS was used instead.  This might fix some weird issues on certain boxes
  where IRQs > 16 don't seem to work when using ACPI.
- Fix a bug with how we walked the resource buffer after _SRS to call
  config_intr() in that the 'end' variable was not properly updated, so we
  could either terminate the loop early or loop after the end of the
  buffer.

back on again in resume.  Override the default of D3 with the value the
BIOS specifies in _SxD, if present.  Skip serial devices (PNP05xx) since
they seem to hang when set to D3 and may require special driver support.
Also, skip non-type 0 PCI devices (i.e., bridges) since our we don't yet

7e1f562e2a - Do a better job of handling any Dependent Functions (aka DPFs) that appear
in the _PRS or _CRS of link devices.  If faced with multiple DPFs in a
  _PRS, we just use the first one.  We assume that if _CRS has DPF tags they
  only contain a single set since multiple DPFs wouldn't make any sense.  In
  practice, the only DPFs I've seen so far for link devices are that the one
  IRQ resource is surrounded by a DPF tag pair for no apparent reason, and
  this should handle that case fine now.
- Only allocate link structures for IRQ resources for link devices rather
  than allocating a link structure for every resource.

ad71daf0cb Make sure the link array is big enough to hold both _CRS and _PRS
resource lists.  It used to be sized based only on _CRS, hence _PRS could
perform an out-of-bounds access if it was larger (i.e., when there are
dependent functions).  Add asserts to detect this case.  Note, this is
only a temporary fix and I believe _PRS and _CRS should have separate

5e1ba6d4ae Rework the ACPI PCI link code.
- Use a new-bus device driver for the ACPI PCI link devices.  The devices
  are called pci_linkX.  The driver includes suspend/resume support so that
  the ACPI bridge drivers no longer have to poke the links to get them
  to handle suspend/resume.  Also, the code to handle which IRQs a link is
  routed to and choosing an IRQ when a link is not already routed is all
  contained in the link driver.  The PCI bridge drivers now ask the link
  driver which IRQ to use once they determine that a _PRT entry does not
  use a hardwired interrupt number.
- The new link driver includes support for multiple IRQ resources per
  link device as well as preserving any non-IRQ resources when adjusting
  the IRQ that a link is routed to.
- The entire approach to routing when using a link device is now
  link-centric rather than pci bus/device/pin specific.  Thus, when
  using a tunable to override the default IRQ settings, one now uses
  a single tunable to route an entire link rather than routing a single
  device that uses the link (which has great foot-shooting potential if
  the user tries to route the same link to two different IRQs using two
  different pci bus/device/pin hints).  For example, to adjust the IRQ
  that \_SB_.LNKA uses, one would set 'hw.pci.link.LNKA.irq=10' from the
  loader.
- As a side effect of having the link driver, unused link devices will now
  be disabled when they are probed.
- The algorithm for choosing an IRQ for a link that doesn't already have an
  IRQ assigned is now much closer to the one used in $PIR routing.  When a
  link is routed via an ISA IRQ, only known-good IRQs that the BIOS has
  already used are used for routing instead of using probabilities to
  guess at which IRQs are probably not used by an ISA device.  One change
  from $PIR is that the SCI is always considered a viable ISA IRQ, so that
  if the BIOS does not setup any IRQs the kernel will degenerate to routing
  all interrupts over the SCI.  For non ISA IRQs, interrupts are picked
  from the possible pool using a simplistic weighting algorithm.

* Add a quirk to disable the timer

500 generates a notify saying the zone needs to be re-evaluated whenever
its fan is switched on or off.  This produced an infinite loop.  Also, note
that running _SCP can generate the same notify.

Since we need to make sure old fan references are turned off when getting
new ones, run acpi_tz_monitor() first.  This will turn off any unneeded
fans.  Then, check for new settings.  After that, run acpi_tz_monitor()
again to turn on/off any fans referenced by the new settings.

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.

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

e4116e931c Re-work ACPI PCI IRQ routing (_PRT, link devices). The old approach was
incomplete in that the PRT routing was not aware of link programming.
Fix this by doing all routing through the link devices.  The new algorithm
for setting up links is:

1. Read _CRS to get current setting.  If invalid (not in _PRS), then set
   to 0.
2. Attempt to call _DIS on the link.  If successful, mark the link as not
   routed.  Otherwise, assume it still is.

Then when a routing request occurs:

3. Update weights for all IRQs
4. Attempt to route the initial IRQ if valid
5. If that fails, walk through the sorted list, attempting to route IRQs.
6. Configure the trigger/polarity based on _PRS.

Other changes:
* Add acpi_pci_find_prt() to look up the PRT entry for a given device and
  acpi_pci_link_route() to select/route the best IRQ for it.
* Remove duplicated code in acpi_pcib_route_interrupt() that picked the
  first IRQ from _PRS.
* Remove unneeded arguments from acpi_pcib_resume() and friends.
* Ignore _STA on link devices but report if it seems strange.
* Add a prt_source handle to the PRT structure since the ACPI struct
  ACPI_PCI_ROUTING_TABLE uses a fixed-size entry for it.  We'll need to
  dynamically size this object if we want to use it the same way ACPI-CA
  does.  Null-terminate the source.

298e3d15d7 Work around non-compliant BIOS PCI link devices. Some systems have the
following behavior:

* Link devices return invalid status (_STA) values.  The results are very
  unreliable -- sometimes never present.  Just ignore the status and pick
  the best configuration from _PRS.

* Link devices return invalid current settings (_CRS).  Even after setting
  the link value, many systems still return a different setting for _CRS.
  When setting an IRQ, don't bother to check _CRS to see if we succeeded.
  Note that we still check _CRS before routing and this should be addressed
  as well.

Since this is a sensitive area, leave the old behavior accessible via
uncommenting the define for ACPI_OLD_PCI_LINK at the top of the file.  Once
this has been thoroughly tested, this option and the code it covers will
be removed.

then other devices can allocate from them.  Otherwise, acpi_timer (the only

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.

75988358a2 Fix several bugs where 32-bit timers and wraparound were not properly
supported.  Symptoms of this bug included unnecessary use of ACPI-safe
and a dmesg that has deltas of about 2^24:

    ACPI timer looks BAD  min = 2, max = 16777206, width = 16777204
    ACPI timer looks BAD  min = 2, max = 7, width = 5
    ACPI timer looks GOOD min = 4, max = 5, width = 1
    ACPI timer looks BAD  min = 2, max = 16777206, width = 16777204
    ACPI timer looks BAD  min = 2, max = 7, width = 5
    ACPI timer looks BAD  min = 2, max = 16777210, width = 16777208
    ACPI timer looks BAD  min = 4, max = 16777189, width = 16777185
    ACPI timer looks GOOD min = 4, max = 5, width = 1
    ACPI timer looks BAD  min = 2, max = 7, width = 5
    ACPI timer looks BAD  min = 4, max = 16777189, width = 16777185

To fix this:
* Use a 32 bit timecounter mask when the timer is 32 bits.
* In test_counter(), use the acpi_TimerDelta function which handles 24/32
  bit timers and wraparound.

Miscellaneous fixes:
* Use C99 initializers for timecounter struct.
* Use u_int and uint32_t where appropriate instead of unsigned.
* Remove whitespace-only lines
* Remove the old PIIX4 PCI workaround.  The timecounter testing code has
  been in use for long enough to prove it's functional.

322141f1e2 If the temperature is at _HOT or _CRT for 3 sequential readings, shutdown

seconds.  This is needed because some systems will report an invalid high
temperature for one poll cycle.  It is suspected this is due to the
embedded controller timing out.  A typical value is 138C for one cycle on a
system that is otherwise 65C.  This prevents the system from prematurely
shutting down after one invalid reading.  It will still shut down after 30
seconds of high temperature, which is the same as previous default
behavior.

447a5fa113 Update this driver to be more module friendly:
- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of
  using a statically sized array that depended on 'options SMP'.
- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
  match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
  disable C3 for SMP machines.

b6426963c4 * Add acpi_pcpu_get_id(idx, *acpi_id, *cpu_id) which fetches the
idx'th present CPU with pc_acpi_id equal to *acpi_id.  If *acpi_id
  does not match that processor's pc_acpi_id, return the value for
  ProcId derived from the MADT in *acpi_id.  If pc_acpi_id is 0xffffffff,
  always override it with the value of *acpi_id.  Finally, return
  pc_cpuid in *cpu_id and use that as our primary key.

* Use pc_cpuid as our unique key because we know it is valid since
  MD code set it.  The values for ProcId in the ASL and MADT don't
  match up on some machines (!), forcing us to fall back to ordered
  probing in that case.

* Remove some #ifdef SMP since the refcount doesn't hurt performance
  and will be needed for dynamic _CST objects.  Only one #ifdef SMP
  (for smp_rendezvous) remains.

* Hook up SMP in the compile flags in the Makefile.

56a70eadf5 * Add a DEVMETHOD for acpi so that child detach methods get called. Add
an acpi_cpu method for shutdown that disables entry to acpi_cpu_idle
  and then IPIs/waits for threads to exit.  This fixes a panic late in
  reboot in the SMP case.

* In the !SMP case, don't use the processor id filled out by the MADT
  since there can only be one processor.  This was causing a panic in
  acpi_cpu_idle if the id was 1 since the data was being dereferenced from
  cpu_softc[1] even though the actual data was in cpu_softc[0] (which is
  correct).

* Rework the initialization functions so that cpu_idle_hook is written
  late in the boot process.

* Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables.
  This will help SMP boxes that have _CST or multiple P_BLKs.  No such
  boxes are known at this time.

* Always allocate the C1 state, even if the P_BLK is invalid.  This means
  we will always take over idling if enabled.  Remove the value -1 as
  valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt.

* Reduce locking for the throttle initialization case to around the write
  to the smi_cmd port.  Add disabled code to write the CST_CNT.  It will
  be enabled once _CST re-evaluation is tested (post 5.2R).

3d9644ef0b Improve support for extended IRQ resources:
- For acpi_pci_link_entry_dump(), add a few helper functions to display
  the trigger mode, polarity, and sharemode of an individual IRQ resource.
  These functions are then called for both regular and extended IRQ
  resources.
- In acpi_pci_link_set_irq(), use the same type of IRQ resource
  (regular vs. extended) for the new current resource as the type of
  the resources from _PRS.
- When routing an interrupt don't ignore extended IRQ resources.  Also,
  use the same type of IRQ resource (regular vs. extended) for the new
  current resource when as the type of the resource from _PRS.
