2008-07-07PCI ACPI: Rework PCI handling of wake-upRafael J. Wysocki
* Introduce function acpi_pm_device_sleep_wake() for enabling and disabling the system wake-up capability of devices that are power manageable by ACPI. * Introduce function acpi_bus_can_wakeup() allowing other (dependent) subsystems to check if ACPI is able to enable the system wake-up capability of given device. * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake(). * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and for the ACPI 'driver' make it use acpi_bus_can_wakeup(). * Move the PME# handlig code out of pci_enable_wake() and split it into two functions, pci_pme_capable() and pci_pme_active(), allowing the caller to check if given device is capable of generating PME# from given power state and to enable/disable the device's PME# functionality, respectively. * Modify pci_enable_wake() to use the new ACPI callbacks and the new PME#-related functions. * Drop the generic .platform_enable_wakeup() callback that is not used any more. * Introduce device_set_wakeup_capable() that will set the power.can_wakeup flag of given device. * Rework PCI device PM initialization so that, if given device is capable of generating wake-up events, either natively through the PME# mechanism, or with the help of the platform, its power.can_wakeup flag is set and its power.should_wakeup flag is unset as appropriate. * Make ACPI set the power.can_wakeup flag for devices found to be wake-up capable by it. * Make the ACPI wake-up code enable/disable GPEs for devices that have the wakeup.flags.prepared flag set (which means that their wake-up power has been enabled).

2008-04-26x86: validate against acpi motherboard resourcesRobert Hancock
This path adds validation of the MMCONFIG table against the ACPI reserved motherboard resources. If the MMCONFIG table is found to be reserved in ACPI, we don't bother checking the E820 table. The PCI Express firmware spec apparently tells BIOS developers that reservation in ACPI is required and E820 reservation is optional, so checking against ACPI first makes sense. Many BIOSes don't reserve the MMCONFIG region in E820 even though it is perfectly functional, the existing check needlessly disables MMCONFIG in these cases. In order to do this, MMCONFIG setup has been split into two phases. If PCI configuration type 1 is not available then MMCONFIG is enabled early as before. Otherwise, it is enabled later after the ACPI interpreter is enabled, since we need to be able to execute control methods in order to check the ACPI reserved resources. Presently this is just triggered off the end of ACPI interpreter initialization. There are a few other behavioral changes here: - Validate all MMCONFIG configurations provided, not just the first one. - Validate the entire required length of each configuration according to the provided ending bus number is reserved, not just the minimum required allocation. - Validate that the area is reserved even if we read it from the chipset directly and not from the MCFG table. This catches the case where the BIOS didn't set the location properly in the chipset and has mapped it over other things it shouldn't have. This also cleans up the MMCONFIG initialization functions so that they simply do nothing if MMCONFIG is not compiled in. Based on an original patch by Rajesh Shah from Intel.

2008-01-11PM: ACPI and APM must not be enabled at the same timeLen Brown
ACPI and APM used "pm_active" to guarantee that they would not be simultaneously active. But pm_active was recently moved under CONFIG_PM_LEGACY, so that without CONFIG_PM_LEGACY, pm_active became a NOP -- allowing ACPI and APM to both be simultaneously enabled. This caused unpredictable results, including boot hangs. Further, the code under CONFIG_PM_LEGACY is scheduled for removal. So replace pm_active with pm_flags. pm_flags depends only on CONFIG_PM, which is present for both CONFIG_APM and CONFIG_ACPI. http://bugzilla.kernel.org/show_bug.cgi?id=9194 Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Rafael J.

2007-08-23ACPI: don't duplicate input events on netlinkZhang Rui
The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events.

2006-06-14ACPI: ACPICA 20060421Bob Moore
Removed a device initialization optimization introduced in 20051216 where the _STA method was not run unless an _INI was also present for the same device. This optimization could cause problems because it could allow _INI methods to be run within a not-present device subtree (If a not-present device had no _INI, _STA would not be run, the not-present status would not be discovered, and the children of the device would be incorrectly traversed.) Implemented a new _STA optimization where namespace subtrees that do not contain _INI are identified and ignored during device initialization. Selectively running _STA can significantly improve boot time on large machines (with assistance from Len Brown.) Implemented support for the device initialization case where the returned _STA flags indicate a device not-present but functioning. In this case, _INI is not run, but the device children are examined for presence, as per the ACPI specification. Implemented an additional change to the IndexField support in order to conform to MS behavior. The value written to the Index Register is not simply a byte offset, it is a byte offset in units of the access width of the parent Index Field. (Fiodor Suietov) Defined and deployed a new OSL interface, acpi_os_validate_address(). This interface is called during the creation of all AML operation regions, and allows the host OS to exert control over what addresses it will allow the AML code to access. Operation Regions whose addresses are disallowed will cause a runtime exception when they are actually accessed (will not affect or abort table loading.) Defined and deployed a new OSL interface, acpi_os_validate_interface(). This interface allows the host OS to match the various "optional" interface/behavior strings for the _OSI predefined control method as appropriate (with assistance from Bjorn Helgaas.) Restructured and corrected various problems in the exception handling code paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod (with assistance from Takayoshi Kochi.) Modified the Linux source converter to ignore quoted string literals while converting identifiers from mixed to lower case. This will correct problems with the disassembler and other areas where such strings must not be modified. The ACPI_FUNCTION_* macros no longer require quotes around the function name. This allows the Linux source converter to convert the names, now that the converter ignores quoted strings.

2006-06-14ACPI: ACPICA 20060331Bob Moore
Implemented header file support for the following additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Implemented the use of a cache object for all internal namespace nodes. Since there are about 1000 static nodes in a typical system, this will decrease memory use for cache implementations that minimize per-allocation overhead (such as a slab allocator.) Removed the reference count mechanism for internal namespace nodes, since it was deemed unnecessary. This reduces the size of each namespace node by about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, and 32 bytes for the 64-bit case. Optimized several internal data structures to reduce object size on 64-bit platforms by packing data within the 64-bit alignment. This includes the frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static instances corresponding to the namespace objects. Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" and "Windows 2006". Split the allocation tracking mechanism out to a separate file, from utalloc.c to uttrack.c. This mechanism appears to be only useful for application-level code. Kernels may wish to not include uttrack.c in distributions. Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING macros.)
