2010-12-17ACPI: Execute _PRW for devices reported as inactive or not presentRafael J. Wysocki
If a device is reported as inactive or not present by its _STA control method, acpi_bus_check_add() skips it without evaluating its _PRW method. This leads to a problem when the device's _PRW method points to a GPE, because in that case the GPE may be enabled by ACPICA during the subsequent acpi_update_gpes() call which, in turn, may cause a GPE storm to appear. To avoid this issue, make acpi_bus_check_add() evaluate _PRW for inactive or not present devices and register the wakeup GPE information returned by them, so that acpi_update_gpes() does not enable their GPEs unnecessarily.

__get_cpu_var() can be replaced with this_cpu_read and will then use a single read instruction with implied address calculation to access the correct per cpu instance. However, the address of a per cpu variable passed to __this_cpu_read() cannot be determed (since its an implied address conversion through segment prefixes). Therefore apply this only to uses of __get_cpu_var where the addres of the variable is not used.

2010-12-14IPMI/ACPI: Add the IPMI opregion driver to enable ACPI to access BMC controllerZhao Yakui
ACPI 4.0 spec adds the ACPI IPMI opregion, which means that the ACPI AML code can also communicate with the BMC controller. This is to install the ACPI IPMI opregion and enable the ACPI to access the BMC controller through the IPMI message. It will create IPMI user interface for every IPMI device detected in ACPI namespace and install the corresponding IPMI opregion space handler. Then it can enable ACPI to access the BMC controller through the IPMI message. The following describes how to process the IPMI request in IPMI space handler: 1. format the IPMI message based on the request in AML code. IPMI system address. Now the address type is SYSTEM_INTERFACE_ADDR_TYPE IPMI net function & command IPMI message payload 2. send the IPMI message by using the function of ipmi_request_settime 3. wait for the completion of IPMI message. It can be done in different routes: One is in handled in IPMI user recv callback function. Another is handled in timeout function. 4. format the IPMI response and return it to ACPI AML code. At the same time it also addes the module dependency. The ACPI IPMI opregion will depend on the IPMI subsystem.

2010-12-13ACPI, APEI, Add APEI generic error status printing supportHuang Ying
In APEI, Hardware error information reported by firmware to Linux kernel is in the data structure of APEI generic error status (struct acpi_hes_generic_status). While now printk is used by Linux kernel to report hardware error information to user space. So, this patch adds printing support for the data structure, so that the corresponding hardware error information can be reported to user space via printk. PCIe AER information printing is not implemented yet. Will refactor the original PCIe AER information printing code to avoid code duplicating. The output format is as follow: <error record> := APEI generic hardware error status severity: <integer>, <severity string> section: <integer>, severity: <integer>, <severity string> flags: <integer> <section flags strings> fru_id: <uuid string> fru_text: <string> section_type: <section type string> <section data> <severity string>* := recoverable | fatal | corrected | info <section flags strings># := [primary][, containment warning][, reset][, threshold exceeded]\ [, resource not accessible][, latent error] <section type string> := generic processor error | memory error | \ PCIe error | unknown, <uuid string> <section data> := <generic processor section data> | <memory section data> | \ <pcie section data> | <null> <generic processor section data> := [processor_type: <integer>, <proc type string>] [processor_isa: <integer>, <proc isa string>] [error_type: <integer> <proc error type strings>] [operation: <integer>, <proc operation string>] [flags: <integer> <proc flags strings>] [level: <integer>] [version_info: <integer>] [processor_id: <integer>] [target_address: <integer>] [requestor_id: <integer>] [responder_id: <integer>] [IP: <integer>] <proc type string>* := IA32/X64 | IA64 <proc isa string>* := IA32 | IA64 | X64 <processor error type strings># := [cache error][, TLB error][, bus error][, micro-architectural error] <proc operation string>* := unknown or generic | data read | data write | \ instruction execution <proc flags strings># := [restartable][, precise IP][, overflow][, corrected] <memory section data> := [error_status: <integer>] [physical_address: <integer>] [physical_address_mask: <integer>] [node: <integer>] [card: <integer>] [module: <integer>] [bank: <integer>] [device: <integer>] [row: <integer>] [column: <integer>] [bit_position: <integer>] [requestor_id: <integer>] [responder_id: <integer>] [target_id: <integer>] [error_type: <integer>, <mem error type string>] <mem error type string>* := unknown | no error | single-bit ECC | multi-bit ECC | \ single-symbol chipkill ECC | multi-symbol chipkill ECC | master abort | \ target abort | parity error | watchdog timeout | invalid address | \ mirror Broken | memory sparing | scrub corrected error | \ scrub uncorrected error <pcie section data> := [port_type: <integer>, <pcie port type string>] [version: <integer>.<integer>] [command: <integer>, status: <integer>] [device_id: <integer>:<integer>:<integer>.<integer> slot: <integer> secondary_bus: <integer> vendor_id: <integer>, device_id: <integer> class_code: <integer>] [serial number: <integer>, <integer>] [bridge: secondary_status: <integer>, control: <integer>] <pcie port type string>* := PCIe end point | legacy PCI end point | \ unknown | unknown | root port | upstream switch port | \ downstream switch port | PCIe to PCI/PCI-X bridge | \ PCI/PCI-X to PCIe bridge | root complex integrated endpoint device | \ root complex event collector Where, [] designate corresponding content is optional All <field string> description with * has the following format: field: <integer>, <field string> Where value of <integer> should be the position of "string" in <field string> description.

commit b0ed7a91(ACPICA/ACPI: Add new host interfaces for _OSI suppor) introduced a regression that _OSI string setup fails. There are 2 paths to setup _OSI string. DMI: acpi_dmi_osi_linux -> set_osi_linux -> acpi_osi_setup -> copy _OSI string to osi_setup_string Boot command line: acpi_osi_setup -> copy _OSI string to osi_setup_string Later, acpi_osi_setup_late will be called to handle osi_setup_string. If _OSI string is "Linux" or "!Linux", then the call path is, acpi_osi_setup_late -> acpi_cmdline_osi_linux -> set_osi_linux -> acpi_osi_setup -> copy _OSI string to osi_setup_string This actually never installs _OSI string(acpi_install_interface not called), but just copy the _OSI string to osi_setup_string.

2010-10-26ACPI: install ACPI table handler before any dynamic tables being loadedZhang Rui
ACPI table sysfs I/F is broken by commit 78f1699659963fff97975df44db6d5dbe7218e55 Author: Alex Chiang <achiang@hp.com> Date: Sun Dec 20 12:19:09 2009 -0700 ACPI: processor: call _PDC early because dynamic SSDT tables may be loaded in _PDC, before installing the ACPI table handler. As a result, the sysfs I/F of these dynamic tables are located at /sys/firmware/acpi/tables instead of /sys/firmware/acpi/tables/dynamic, which is not true. Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(), so that the table handler is installed before any dynamic tables loaded. https://bugzilla.kernel.org/show_bug.cgi?id=21142 CC: Dennis Jansen <dennis.jansen@web.de> CC: Alex Chiang <achiang@hp.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
