9b0df55b61 Create an identity mapping (V=P) super page for the low memory region on
boot.  Then, just switch to the kernel pmap when suspending instead of
allocating/freeing our own mapping every time.  This should solve a panic
of pmap_remove() being called with interrupts disabled.  Thanks to Alan
Cox for developing this patch.

Note: this means that ACPI requires super page (PG_PS) support in the CPU.
This has been present since the Pentium and first documented in the
Pentium Pro.  However, it may need to be revisited later.

4962065404 Refine previous revision to allow acpi_wakecode.h to be safely built
from both the acpi module build directory and a kernel build directory.
The latter didn't work when one attempted to build a kernel which had
"device acpi" with the "make kernel-toolchain buildkernel" command
because a cross-compiler couldn't find anything in the standard system
include path (it's empty in the kernel-toolchain case).

Fix this by passing a better root path to kernel headers (src/sys)
which works for both cases, kernel and module (-I@ only worked for
module).

Also, while here, pass -nostdinc (and a different spelling for icc) --
it's a feature that the kernel source tree is self-contained, and this
change enforces this.

7e9f73f3ed First pass at allowing memory to be mapped using cache modes other than
WB (write-back) on x86 via control bits in PTEs and PDEs (including making
use of the PAT MSR).  Changes include:
- A new pmap_mapdev_attr() function for amd64 and i386 which takes an
  additional parameter (relative to pmap_mapdev()) specifying the cache
  mode for this mapping.  Note that on amd64 only WB mappings are done with
  the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
  mappings rather than WB.  Previously we relied on the BIOS setting up
  MTRR's to enforce memio regions being treated as UC.  This might make
  hw.cbb_start_memory unnecessary in some cases now for example.
- A new pmap_mapbios()/pmap_unmapbios() API has been added to allow places
  that used pmap_mapdev() to map non-device memory (such as ACPI tables)
  to do so using WB as before.
- A new pmap_change_attr() function for amd64 and i386 that changes the
  caching mode for a range of KVA.

5bb84bc84b Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in
  memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
  as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
  memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
  attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion.  Similar changes are required for UMA zone names.

76f6fe4f31 Rewrite the acpi_battery interface to allow for other battery types
(i.e., smart battery) and fix various bugs found during the cleanup.

API changes:
* kernel access:
Access to individual batteries is now via devclass_find("battery").
Introduce new methods ACPI_BATT_GET_STATUS (for _BST-formatted data) and
ACPI_BATT_GET_INFO (for _BIF-formatted data).  The helper function
acpi_battery_get_battinfo() now takes a device_t instead of a unit #
argument.  If dev is NULL, this signifies all batteries.

* ioctl access:
The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been
removed.  Since there is now no need for a mapping between "virtual" unit
and physical unit, usermode programs can just specify the unit directly and
skip the old translation steps.  In fact, acpiconf(8) was actually already
doing this and virtual unit was the same as physical unit in all cases
since there was previously only one battery type (acpi_cmbat).  Additionally,
we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all
batteries, if they provide the associated methods.

* apm compatibility device/ioctls:  no change
* sysctl:  no change

Since most third-party applications use the apm(4) compat interface, there
should be very few affected applications (if any).

0cafadacae Remove the attempt to cache the previous page mapped at our identity
location (for the wake code).  It should not be needed since we don't
map other pages at the same location and if there was an old mapping, it
would be restored by a fault.  The old code had serious problems, namely
that it was restoring the new page it had just removed (not opage) and
it could only guess at the right protection (since there's no
pmap_extract_protect function).  Thanks to Alan Cox for explaining much
of this to me.

Also, remove a commented-out initializecpu() call since it is not needed.
Restoring the cpu context is better than attempting to init from scratch.

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
  edge/high.
- 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.

gadgets (hotkeys, lcd, ...) on Asus laptops.  I aim to closely track the
acpi4asus project which implements these features in the Linux kernel.

If this breaks your laptop, please let me know how it does it :-)

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.

a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:
 - in_cksum.[ch]:

     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

Incarnations of this patch survive gcc compiles since a loooong time,

(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

afa632035c - Call acpi_Startup() before parsing interrupt-related APIC resources so we
can look at the ACPI tables.  If the startup fails, we panic and tell the
  user to try rebooting with ACPI disabled.  Previously in this case we
  would try to use $PIR interrupt routing which only works for the atpic
  while using the apic to handle interrupts which would result in misrouted
  interrupts and a hang at boot time with no error message.
- Read the SCI out of the FADT instead of hardcoding 9 when checking to see
  if an interrupt override entry is for the SCI.
- Try to work around some BIOS brain damage for the SCI's programming by
  forcing the SCI to be level triggered and active low if it is routed
  to a non-ISA interrupt (greater than 15) or if it is identity mapped with
  edge trigger and active high polarity.  This should fix some of the hangs
  with device apic and ACPI that some people see.

6afad3b055 - Reorder the APIC enumerator SYSINIT's to register enumeators at

  help get the ACPI module working again as it moves the APIC enumeration
  code after SI_SUB_KLD.
- In the MADT parser, use mp_maxid rather than MAXCPU to terminate a loop
  when assigning per-cpu ACPI IDs to avoid a dependency on 'options SMP'.
- Allow the apic device to be disabled via 'hint.apic.0.disabled' from the

d3c01334ce Some motherboards like to remap the SCI (normally IRQ 9) up to a PCI
interrupt such as IRQ 22 or 19.  However, the ACPI BIOS still routes
interrupts from some PCI devices to the same intpin calling the pin
IRQ 22.  Thus, ACPI expects to address a single interrupt source via two
different names.  To work around this, if the SCI is remapped to a non-ISA
interrupt (i.e., greater than 15), then we use
acpi_OverrideInterruptLevel() function to tell ACPI to use IRQ 22 or 19
rather than IRQ 9 for the SCI.

Previously we would change IRQ 22 or 19's name to IRQ 9 when we encountered
such an Interrupt Source Override entry in the MADT which routed the SCI
properly but left PCI devices mapped to IRQ 22 or 19 w/o a routable
interrupt.

pin that is used by the default identity mapping if it still maps to the

ab089945d3 Add the ACPI MADT table APIC enumerator. This code uses the ACPI Multiple
APIC Descriptor Table to enumerate both I/O APICs and local APICs.  ACPI
does not embed PCI interrupt routing information in the MADT like the MP
Table does.  Instead, ACPI stores the PCI interrupt routing information
in the _PRT object under each PCI bus device.  The MADT table simply
provides hints about which interrupt vectors map to which I/O APICs.  Thus
when using ACPI, the existing ACPI PCI bridge drivers are sufficient to
route PCI interrupts.
