- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Add TCG ACPI spec table (TCPA) support.

Submitted by: Hans-Joerg_Hoexer@genua.de

- Use the headers from ACPI-CA to define various constants and structures
for table layouts, etc. rather than homerolling our own structures and
constants in acpidump.h.
- Verify the extended checksum on the RSDP.
- Handle new ACPI 3.0 fields in MADT including X2APIC entries and
UIDs for local SAPICs.
- Add handling for new ACPI 3.0 flags in the FADT.

Fix a small style problem and add a __packed pragma for safety.

Add support for parsing MCFG tables.

Back out the -s flag and go back to dumping the SSDTs by default.

Add the -s flag to make dumping SSDTs optional (disabled by default).
Since we can only override the DSDT, a custom ASL dumped previously that
contained SSDTs would result in lots of multiple definition errors.

A longer-term fix involves adding the ability to override SSDTs to ACPI-CA.

Add support for SSDT tables. Dumping or disassembling the DSDT will
now include the contents if any SSDT table as well. This makes use
of the property that one can concatenate the body of SSDT tables to
the DSDT, updating the DSDT header (length and checksum) and end up
with a larger and valid DSDT table. Hence, this also works with -f.

Unify the start/size parameters for the RSDP search area. Don't bother
trying to exclude the top end of the range since it should hurt to overlap
by 4 bytes in the off-chance the RSDP signature appears incorrectly at the
very top of our search space.

Use the correct location of the EBDA for searching for the RSDP.
The EBDA is the 1 KB area addressed by the 16 bit pointer at 0x40E.

Pointed out by: robert.moore AT intel.com

Instead of scanning the entire lower 1 MB of RAM, only scan locations
where the RSD PTR can actually occur. According to section 5.2.2
of the ACPI spec, we only consider two regions for the base address:

1. EBDA (0x0 - 0x3FF)
2. High memory (0xE0000 - 0xFFFFF)

I don't know whether this fixes any actual problems but is more correct.

Minor style issues.

Rename FACP to FADT throughout.

Print FACS contents.
Remove unused code.

Modify acpidump to use iasl(8) as the backend for disassembling AML.
Also clean up the output of dumped tables. Update the man page for the
new usage. Make WARNS=6 clean.

Dump the HPET information block.

What is the HPET I hear you ask? It is the High Precision Event Timer
that is supposed to supplement and eventually replace the 8254 timer and
the RTC periodic interrupts. Among other things, it is 64 bit (can be
run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for
the ACPI timer on SMP systems (the specs are much better) and as a
replacement for the ITC based synthetic clock for on ia64 systems.

It seems IA64 and AMD64 systems tend to have this. It is likely to start
showing up in i386 systems if it isn't already on some of them.

Add structure definitions for the various items in a ACPI Multiple

o Use sysctl machdep.acpi_root to get the physical address of the
RSDP. Scan the first 1MB on i386 if the sysctl fails,
o Extend struct ACPIrsdp with the ACPI 2.0 fields which involves
changing a prior reserved field into the ACPI revision,
o Only calculate the RSDP checksum on the first 20 bytes to remain
compatible with ACPI 1.0 tables; we don't check the extended
checksum covering the whole table,
o Use the length field in the RSDP to map the RSDP into the address
space so that we don't have to know about future extensions here.

Use __packed.

Add support for decoding Buffer objects that contain PnP/ACPI resource
streams. Since the output is bulky, it's controlled by the '-r'
option.

Document this in the manpage, and clean up some awkward English a
little.

Fix UserTerms disassembling. Now that dumped ASL can be compiled with
ports/devel/acpitools (iasl).
- Merge AML parser to build ACPI namespace
- Comment header info. out so that ASL compiler ignore them
- Fix DSDT header size to be discarded when DSDT file is specified

- Fix some trivial typo (Concatenate and SizeOf)
- Remove DEBUG_FLAGS from Makefile (acpidump and amldb)

Remove dependence on old acpi driver from acpi userland tools.

- acpiconf Replace include files from old acpi driver to acpica driver.
New sleep type `4b' had been added (S4BIOS) for `-s' option.
Of course this has no effect because driver doesn't
support it for now :-)

- acpidump All needed structs in sys/dev/acpi/*.h had been merged
into local header file. No changes on its usage.
