      [PATCH] x86_64: Disable ACPI blacklist by year for now on x86-64 · 2eb1bdba
      由 Andi Kleen 提交于 
      ACPI is initialized very early on x86-64, before the DMI code is
initialized.  This means it would often discover a 0 year and then turn
off ACPI because it thought the BIOS was too old.  Some systems don't
boot without ACPI so this was a problem.

I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged.  For 2.6.16 let's just turn the
check off.  It never made much sense anyways because there are no x86-64
systems older than 2002 or so and they generally all have working ACPI.

      [PATCH] x86-64/i386: Use common X86_PM_TIMER option and make it EMBEDDED · e78256b8
      由 Andi Kleen 提交于 
      This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi

And since PM timer is needed for correct timing on a lot of systems
now (e.g. AMD dual cores) and we often get bug reports from people
who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had
this change before and it's a good thing.

I also fixed the description slightly to make this more clear.

      由 Bob Moore 提交于 
      Implemented support in the Resource Manager to allow
unresolved namestring references within resource package
objects for the _PRT method. This support is in addition
to the previously implemented unresolved reference
support within the AML parser. If the interpreter slack
mode is enabled (true on Linux unless acpi=strict),
these unresolved references will be passed through
to the caller as a NULL package entry.
http://bugzilla.kernel.org/show_bug.cgi?id=5741

Implemented and deployed new macros and functions for
error and warning messages across the subsystem. These
macros are simpler and generate less code than their
predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION,
ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_*
macros.

Implemented the acpi_cpu_flags type to simplify host OS
integration of the Acquire/Release Lock OSL interfaces.
Suggested by Steven Rostedt and Andrew Morton.

Fixed a problem where Alias ASL operators are sometimes
not correctly resolved. causing AE_AML_INTERNAL
http://bugzilla.kernel.org/show_bug.cgi?id=5189
http://bugzilla.kernel.org/show_bug.cgi?id=5674

Fixed several problems with the implementation of the
ConcatenateResTemplate ASL operator. As per the ACPI
specification, zero length buffers are now treated as a
single EndTag. One-length buffers always cause a fatal
exception. Non-zero length buffers that do not end with
a full 2-byte EndTag cause a fatal exception.

Fixed a possible structure overwrite in the
AcpiGetObjectInfo external interface. (With assistance
from Thomas Renninger)

      Added 2006 copyright.

At SuSE's suggestion, enabled all error messages
without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n

Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages
in the non-debug version of the ACPICA code (this has been
referred to as the "debug lite" option.) Over 200 cases
were converted to create a total of over 380 error/warning
messages across the ACPICA code. This increases the code
and data size of the default non-debug version by about 13K.
Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
The size of the debug version remains about the same.

      由 Bob Moore 提交于 
      Implemented optional support to allow unresolved names
within ASL Package objects. A null object is inserted in
the package when a named reference cannot be located in
the current namespace. Enabled via the interpreter slack
flag which Linux has enabled by default (acpi=strict
to disable slack).  This should eliminate AE_NOT_FOUND
exceptions seen on machines that contain such code.

Implemented an optimization to the initialization
sequence that can improve boot time. During ACPI device
initialization, the _STA method is now run if and only
if the _INI method exists. The _STA method is used to
determine if the device is present; An _INI can only be
run if _STA returns present, but it is a waste of time to
run the _STA method if the _INI does not exist. (Prototype
and assistance from Dong Wei)

Implemented use of the C99 uintptr_t for the pointer
casting macros if it is available in the current
compiler. Otherwise, the default (void *) cast is used
as before.

Fixed some possible memory leaks found within the
execution path of the Break, Continue, If, and CreateField
operators. (Valery Podrezov)

Fixed a problem introduced in the 20051202 release where
an exception is generated during method execution if a
control method attempts to declare another method.

      [PATCH] ACPI: fix sleeping whilst atomic warnings on resume · a64882e7
      由 Dave Jones 提交于 
      This has been broken for months.  On resume, we call acpi_pci_link_set()
with interrupts off, so we get a warning when we try to do a kmalloc of non
atomic memory.  The actual allocation is just 2 long's (plus extra byte for
some reason I can't fathom), so a simple conversion to GFP_ATOMIC is
probably the safest way to fix this.

The error looks like this..

      由 Bob Moore 提交于 
      Modified the parsing of control methods to no longer
create namespace objects during the first pass of the
parse. Objects are now created only during the execute
phase, at the moment the namespace creation operator
is encountered in the AML (Name, OperationRegion,
CreateByteField, etc.) This should eliminate ALREADY_EXISTS
exceptions seen on some machines where reentrant control
methods are protected by an AML mutex. The mutex will now
correctly block multiple threads from attempting to create
the same object more than once.

Increased the number of available Owner Ids for namespace
object tracking from 32 to 255. This should eliminate the
OWNER_ID_LIMIT exceptions seen on some machines with a
large number of ACPI tables (either static or dynamic).

Enhanced the namespace dump routine to output the owner
ID for each namespace object.

      由 Bob Moore 提交于 
      Fixed a problem in the AML parser where the method thread
count could be decremented below zero if any errors
occurred during the method parse phase. This should
eliminate AE_AML_METHOD_LIMIT exceptions seen on some
machines. This also fixed a related regression with the
mechanism that detects and corrects methods that cannot
properly handle reentrancy (related to the deployment of
the new OwnerId mechanism.)

Eliminated the pre-parsing of control methods (to detect
errors) during table load. Related to the problem above,
this was causing unwind issues if any errors occurred
during the parse, and it seemed to be overkill. A table
load should not be aborted if there are problems with
any single control method, thus rendering this feature
rather pointless.

Fixed a problem with the new table-driven resource manager
where an internal buffer overflow could occur for small
resource templates.

Implemented a new external interface, acpi_get_vendor_resource()
This interface will find and return a vendor-defined
resource descriptor within a _CRS or _PRS
method via an ACPI 3.0 UUID match. (from Bjorn Helgaas)

Removed the length limit (200) on string objects as
per the upcoming ACPI 3.0A specification. This affects
the following areas of the interpreter: 1) any implicit
conversion of a Buffer to a String, 2) a String object
result of the ASL Concatentate operator, 3) the String
object result of the ASL ToString operator.

      由 Bob Moore 提交于 
      Modified the subsystem initialization sequence to improve
GPE support. The GPE initialization has been split into
two parts in order to defer execution of the _PRW methods
(Power Resources for Wake) until after the hardware is
fully initialized and the SCI handler is installed. This
allows the _PRW methods to access fields protected by the
Global Lock. This will fix systems where a NO_GLOBAL_LOCK
exception has been seen during initialization.

Fixed a regression with the ConcatenateResTemplate()
ASL operator introduced in the 20051021 release.

Implemented support for "local" internal ACPI object
types within the debugger "Object" command and the
acpi_walk_namespace() external interfaces. These local
types include RegionFields, BankFields, IndexFields, Alias,
and reference objects.

Moved common AML resource handling code into a new file,
"utresrc.c". This code is shared by both the Resource
Manager and the AML Debugger.

      Implemented support for the EM64T and other x86_64
processors. This essentially entails recognizing
that these processors support non-aligned memory
transfers. Previously, all 64-bit processors were assumed
to lack hardware support for non-aligned transfers.

Completed conversion of the Resource Manager to nearly
full table-driven operation. Specifically, the resource
conversion code (convert AML to internal format and the
reverse) and the debug code to dump internal resource
descriptors are fully table-driven, reducing code and data
size and improving maintainability.

The OSL interfaces for Acquire and Release Lock now use a
64-bit flag word on 64-bit processors instead of a fixed
32-bit word. (Alexey Starikovskiy)

Implemented support within the resource conversion code
for the Type-Specific byte within the various ACPI 3.0
*WordSpace macros.

Fixed some issues within the resource conversion code for
the type-specific flags for both Memory and I/O address
resource descriptors. For Memory, implemented support
for the MTP and TTP flags. For I/O, split the TRS and TTP
flags into two separate fields.
