This touches lots of files mainly because of how the io_apic nmi_watchdog was implemented. Now that the io_apic nmi_watchdog is forever gone, remove all its fingers. Most of this code was not being exercised by virtue of nmi_watchdog != NMI_IO_APIC, so there shouldn't be anything to risky here.

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. This patch fixes the regression.

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.

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.

Wysocki" Date: Fri, 17 Dec 2010 22:34:01 +0100 Subject: ACPI: Execute _PRW for devices reported as inactive or not present 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.

Wysocki" Date: Thu, 6 Jan 2011 23:32:23 +0100 Subject: ACPI / ACPICA: Fix global lock acquisition There are two problems with the ACPICA's current implementation of the global lock acquisition. First, acpi_ev_global_lock_handler(), which in fact is an interface to the outside of the kernel, doesn't validate its input, so it only works correctly if the other side (i.e. the ACPI firmware) is fully specification-compliant (as far as the global lock is concerned). Unfortunately, that's known not to be the case on some systems (i.e. we get spurious global lock signaling interrupts without the pending flag set on some systems). Second, acpi_ev_global_lock_handler() attempts to acquire the global lock on behalf of a thread waiting for it without checking if there actually is such a thread. Both of these shortcomings need to be addressed to prevent all possible race conditions from happening. Rework acpi_ev_global_lock_handler() so that it doesn't try to acquire the global lock and make it signal the availability of the global lock to the waiting thread instead. Make sure that the availability of the global lock can only be signaled when there is a thread waiting for it and that it can't be signaled more than once in a row (to keep acpi_gbl_global_lock_semaphore in balance).

Wysocki" Date: Thu, 6 Jan 2011 23:34:22 +0100 Subject: ACPI / PM: Use device wakeup flags for handling ACPI wakeup devices There are ACPI devices (buttons and the laptop lid) that can wake up the system from sleep states and have no "physical" companion devices. The ACPI subsystem uses two flags, wakeup.state.enabled and wakeup.flags.always_enabled, for handling those devices, but they are not accessible through the standard device wakeup infrastructure. User space can only control them via the /proc/acpi/wakeup interface that is not really convenient (e.g. the way in which devices are enabled to wake up the system is not portable between different systems, because it requires one to know the devices' "names" used in the system's ACPI tables). To address this problem, use standard device wakeup flags instead of the special ACPI flags for handling those devices.

Because the memory area used to transfer hardware error information from BIOS to Linux can be determined only in NMI, IRQ or timer handler, but general ioremap can not be used in atomic context, so a special version of atomic ioremap is implemented for that. Known issue: - Error information can not be printed for recoverable errors notified via NMI, because printk is not NMI-safe. Will fix this via delay printing to IRQ context via irq_work or make printk NMI-safe. v2: - adjust printk format per comments.

These objects are then used when setting and reading the power states of devices using the corresponding power resources. Unfortunately, acpi_power_driver is registered after acpi_scan_init() that may add devices using the power resources before acpi_power_driver has a chance to create struct acpi_power_resource objects for them (specifically, the power resources may be referred to during the scanning process through acpi_bus_get_power() before they have been initialized). As the first step towards fixing this issue, move the registration of acpi_power_driver into acpi_scan_init() so that power resource devices can be initialized by it as soon as they have been found in the namespace.

Before a cpuidle driver with one (C1, halt) state got registered Now the default_idle function will be used which finally uses the same idle call to enter sleep state (safe_halt()), but without registering a whole cpuidle driver. That means idle= param will always avoid cpuidle drivers to register with one exception (same behavior as before): idle=nomwait may still register acpi_idle cpuidle driver, but C1 will not use mwait, but hlt. This can be a workaround for IO based deeper sleep states where C1 mwait causes problems.

Bring the code ordering in acpi_pci_root_init() back to sanity. Additionally, make sure that hest_disable is set when acpi_disabled is set, which is going to prevent acpi_hest_parse(), that still may be executed for acpi_disabled=1 through aer_acpi_firmware_first(), from crashing because of uninitialized hest_tab.

b23fffd778c312b8fb258d342051fcbdf6712128 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 20 Jan 2011 13:14:10 -0800 Subject: ACPI / Battery: remove battery refresh on resume This partially reverts commit da8aeb92d4853f37e281f11fddf61f9c7d84c3cd ("ACPI / Battery: Update information on info notification and resume"), which causes a hang on resume on at least some machines. This bug was bisected on an ASUS EeePC 901, which hangs at resume time if we do that "acpi_battery_refresh(battery)" in the battery resume function. Rafael suspects we'll still need to refresh the sysfs files upon resume, but that that can be done from a PM notifier (that will run after thawing user space).

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

Wysocki" Date: Wed, 19 Jan 2011 22:27:14 +0100 Subject: ACPI: Introduce acpi_os_ioremap() Commit ca9b600be38c ("ACPI / PM: Make suspend_nvs_save() use acpi_os_map_memory()") attempted to prevent the code in osl.c and nvs.c from using different ioremap() variants by making the latter use acpi_os_map_memory() for mapping the NVS pages. However, that also requires acpi_os_unmap_memory() to be used for unmapping them, which causes synchronize_rcu() to be executed many times in a row unnecessarily and introduces substantial delays during resume on some systems. Instead of using acpi_os_map_memory() for mapping the NVS pages in nvs.c introduce acpi_os_ioremap() calling ioremap_cache() and make the code in both osl.c and nvs.c use it.

Wysocki" Date: Wed, 19 Jan 2011 22:27:55 +0100 Subject: ACPI / PM: Call suspend_nvs_free() earlier during resume It turns out that some device drivers map pages from the ACPI NVS region during resume using ioremap(), which conflicts with ioremap_cache() used for mapping those pages by the NVS save/restore code in nvs.c. Make the NVS pages mapped by the code in nvs.c be unmapped before device drivers' resume routines run. Signed-off-by: Rafael J.
