[ACPI] restore PCI Interrupt Link Devices upon resume
* register as as a sys_device so that we can get resume callbacks and
restore
interrupt routing state.
* add acpi_pci_link_resume(), which will be called when resuming from
a suspend
state that needs IRQ routing to be restored. This fixes issues
reported on
the mailing lists, e.g.:
http://marc.theaimsgroup.com/?l=acpi4linux&m=109142999328643&w=2
* rename setonboot --> initialized
* change to test acpi_noirq in init
We want to initialize everything on S3 resume in case the BIOS points
an
interrupt link somewhere we didn't expect. (Doing so avoids "missing
interrupt"
or "irq x: nobody cared" problems.) According to Len, past experience
has shown
that it's a good idea to initialize only devices that exist or were
explicitly
asked for, so we try to initialize only the IRQ's that were
previously
initialized at some point before suspend, by checking the
"initialized" flag.
This corresponds to links that have PCI devices attached. Everything
else, we
leave alone. Assuming the BIOS does the same thing on resume that it
did on
boot, this will leave all the unused links in the same state that
they were on
boot.
We are registered as a sysdev in order to do this work fairly early
during
resume, before devices are resumed; some devices may not call
pci_device_enable.
Previous "setonboot once" behavior is left in place, to be
conservative.

[ACPI] ACPICA 20040715 from Bob Moore
Restructured the internal HW GPE interfaces to pass/track
the current state of interrupts (enabled/disabled) in
order to avoid possible deadlock and increase flexibility
of the interfaces.
Implemented a "lexicographical compare" for String and
Buffer objects within the logical operators -- LGreater,
LLess, LGreaterEqual, and LLessEqual -- as per further
clarification to the ACPI specification. Behavior is
similar to C library "strcmp".
Completed a major reduction in CPU stack use for the
acpi_get_firmware_table external function. In the 32-bit
non-debug case, the stack use has been reduced from 168
bytes to 32 bytes.
Deployed a new run-time configuration flag,
acpi_gbl_enable_interpeter_slack, whose purpose is to allow
the AML interpreter to forgive certain bad AML constructs.
Default setting is FALSE.
Implemented the first use of acpi_gbl_enable_interpeter_slack
in the Field IO support code. If enabled, it allows field
access to go beyond the end of a region definition if the
field is within the region length rounded up to the next
access width boundary (a common coding error.)
Renamed OSD_HANDLER to acpi_osd_handler, and
OSD_EXECUTION_CALLBACK to acpi_osd_exec_callback for
consistency with other ACPI symbols. Also, these symbols
are lowercased by the latest version of the acpisrc tool.
The prototypes for the PCI interfaces in acpiosxf.h
have been updated to rename "register" to simply "reg"
to prevent certain compilers from complaining.

[ACPI] ACPICA 20040527 from Bob Moore
Completed a new design and implementation for EBDA
(Extended BIOS Data Area) support in the RSDP scan code.
The original code improperly scanned for the EBDA by simply
scanning from memory location 0 to 0x400. The correct
method is to first obtain the EBDA pointer from within
the BIOS data area, then scan 1K of memory starting at the
EBDA pointer. There appear to be few if any machines that
place the RSDP in the EBDA, however.

Integrated a fix for a possible fault during evaluation
of BufferField arguments. Obsolete code that was causing
the problem was removed. (Asus laptop boot crash)
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121760
Found and fixed a problem in the Field Support Code
where data could be corrupted on a bit field read that
starts on an aligned boundary but does not end on an
aligned boundary. Merged the read/write "datum length"
calculation code into a common procedure.

[ACPI] ACPICA 20040514 from Bob Moore
Fixed a problem where hardware GPE enable bits sometimes
not set properly during and after GPE method execution.
Result of ACPICA 20040427 changes.
Removed extra "clear all GPEs" when sleeping/waking.
Removed acpi_ht_enable_gpe and acpi_hw_disable_gpe, replaced
by the single acpi_hw_write_gpe_enable_reg. Changed a couple
of calls to the functions above to the new acpi_ev* calls
as appropriate.
ACPI_OS_NAME was removed from the OS-specific headers.
The default name is now "Microsoft Windows NT" for maximum
compatibility. However this can be changed by modifying
the acconfig.h file. Fixes EHCI probe issue:
http://bugme.osdl.org/show_bug.cgi?id=1762
Allow a single invocation of acpi_install_notify_handler
for a handler that traps both types of notifies (System,
Device). Use ACPI_ALL_NOTIFY flag.
Run _INI methods on ThermalZone objects. This is against
the ACPI specification, but there is apparently ASL code
in the field that has these _INI methods, and apparently
"other" AML interpreters execute them.
Performed a full 16/32/64 bit lint that resulted in some
small changes.
<len.brown@xxxxxxxxx> (04/05/07 1.1371.717.23)
[ACPI] ACPICA 20040427 from Bob Moore
Completed a major overhaul of the GPE handling within ACPI CA.
There are now three types of GPEs:
wake-only; runtime-only; combination wake/run.
The only GPEs allowed to be combination wake/run are for
button-style devices such as a control-method power button,
control-method sleep button, or a notebook lid switch.
GPEs that have an _Lxx or _Exx method and are not referenced
by any _PRW methods are marked for "runtime" and hardware enabled.
Any GPE that is referenced by a _PRW method is marked for "wake"
(and disabled at runtime). However, at sleep time, only those
GPEs that have been specifically enabled for wake via the
acpi_enable_gpe() interface will actually be hardware enabled.
A new external interface has been added, acpi_set_gpe_type()
that is meant to be used by device drivers to force a GPE
to a particular type. It will be especially useful for the
drivers for the button devices mentioned above.
Completed restructuring of the ACPI CA initialization sequence
so that default operation region handlers are installed
before GPEs are initialized and the _PRW methods are executed.
This will prevent errors when the _PRW methods attempt to
access system memory or I/O space.
GPE enable/disable no longer reads the GPE enable register.
We now keep the enable info for runtime and wake separate
and in the GPE_EVENT_INFO. We thus no longer depend on
the hardware to maintain these bits.
Always clear the wake status and fixed/GPE status bits
before sleep, even for state S5.
Improved the AML debugger output for displaying the
GPE blocks and their current status.
Added new strings for the _OSI method, of the form
"Windows 2001 SPx" where x = 0,1,2,3,4.
Fixed a problem where the physical address was incorrectly
calculated when the Load() operator was used to directly
load from an Operation Region (vs. loading from a Field object.)
Also added check for minimum table length for this case.
Fix for multiple mutex acquisition. Restore original thread
SyncLevel on mutex release.
Added ACPI_VALID_SXDS flag to the acpi_get_object_info interface
for consistency with the other fields returned.
Shrunk the ACPI_GPE_EVENT_INFO structure by 40%.
There is one such structure for each GPE in the system,
so the size of this structure is important.
CPU stack requirement reduction:
Cleaned up the method execution and object evaluation paths
so that now a parameter structure is passed, instead of copying
the various method parameters over and over again.
In evregion.c:
Correctly exit and reenter the interpreter region if and only
if dispatching an operation region request to a user-installed
handler. Do not exit/reenter when dispatching to a default
handler (e.g., default system memory or I/O handlers)
<len.brown@xxxxxxxxx> (04/05/07 1.1371.717.22)
[ACPI] ACPICA 20040402 from Bob Moore
Fixed an interpreter problem where an indirect store through an
ArgX parameter was incorrectly applying the "implicit conversion
rules" during the store. From the ACPI specification: "If the
target is a method local or argument (LocalX or ArgX), no
conversion is performed and the result is stored directly to the
target". The new behavior is to disable implicit conversion
during ALL stores to an ArgX.
Changed the behavior of the _PRW method scan to ignore any and
all errors returned by a given _PRW. This prevents the scan from
aborting from the failure of any single _PRW.
Moved the runtime configuration parameters from the global init
procedure to static variables in acglobal.h. This will allow the
host to override the default values easily.
