bd8a6e05f8 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.

42eeb428c1 When remapping an ISA interrupt from one intpin to another, disable the
pin that is used by the default identity mapping if it still maps to the
old vector.  The ACPI case might need some tweaking for the SCI interrupt
case since ACPI likes to address the intpin using both the IRQ remapped to
it as well as the previous existing PCI IRQ mapped to it.

327da31882 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.

45949ccde1 Commit MD parts of a loosely functional AMD64 port. This is based on
a heavily stripped down FreeBSD/i386 (brutally stripped down actually) to
attempt to get a stable base to start from.  There is a lot missing still.
Worth noting:
- The kernel runs at 1GB in order to cheat with the pmap code.  pmap uses
  a variation of the PAE code in order to avoid having to worry about 4
  levels of page tables yet.
- It boots in 64 bit "long mode" with a tiny trampoline embedded in the
  i386 loader.  This simplifies locore.s greatly.
- There are still quite a few fragments of i386-specific code that have
  not been translated yet, and some that I cheated and wrote dumb C
  versions of (bcopy etc).
- It has both int 0x80 for syscalls (but using registers for argument
  passing, as is native on the amd64 ABI), and the 'syscall' instruction
  for syscalls.  int 0x80 preserves all registers, 'syscall' does not.
- I have tried to minimize looking at the NetBSD code, except in a couple
  of places (eg: to find which register they use to replace the trashed
  %rcx register in the syscall instruction).  As a result, there is not a
  lot of similarity.  I did look at NetBSD a few times while debugging to
  get some ideas about what I might have done wrong in my first attempt.

783ae539c3 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

0ae911eb0e Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

6317601ef1 Export the physical address of the RSDP to userland by means
of the `machdep.acpi_root' sysctl. This is required on ia64
because the root pointer hardly ever, if at all, lives in the
first MB of memory and also because scanning the first MB of
memory can cause machine checks.
This provides a save and reliable way for ACPI tools to work
with the tables if ACPI support is present in the kernel. On
ia64 ACPI is non-optional.

fbf4456fd8 *sigh*. It seems that in the ACPICA code, Intel defines its own APIC_IO
macro for use when parsing MADT tables, thus we always tried to set the
interrupt model to APIC.  This proved to be harmful on UP machines with
IO APIC's (or for UP kernels on SMP machines) since the wrong interrupt
routing information would be returned.

1e51eacf83 Trash the PnPBIOStable pointer later on when we know that the acpi probe
and attach routines have succeeded so that if they fail we can still use
the PnP BIOS to find ISA on-board devices.  The fact that we do this here
is gross but fixing it properly involves a lot more work.

37688d6327 Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support.
- Add S4BIOS sleep implementation.  This will works well if MIB
   hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
   is enabled correctly).
 - Add DSDT overriding support which is submitted by takawata originally.
   If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
   acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
   ACPI CA core loads DSDT from given file rather than BIOS memory block.
   DSDT file can be generated by iasl in ports/devel/acpicatools/.
 - Add new files so that we can add our proposed additional code to Intel
   ACPI CA into these files temporary.  They will be removed when
   similar code is added into ACPI CA officially.

1b24a8aa4e Add APM compatibility feature to ACPI.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications.  The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
 - APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
 - APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
 - APMIO_GETINFO and APMIO_GETINFO_OLD
 - APMIO_GETPWSTATUS

With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)
