Subject: [GIT PATCH] ACPI patches for 2.6.25-rc0
Date: Thu, 7 Feb 2008 04:50:08 -0500	[thread overview]
Message-ID: <200802070450.09098.lenb@kernel.org> (raw)

Hi Linus,

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release

Hmmm, where to begin...
The standard platform specific driver updates, thinkpad, sony, asus
Thermal extensions to support Intel's new Menlo platform.
INITRAMFS DSDT override, a patch I resisted for years, but finally was convinced.
/sys/firmware/acpi/interrupts/ to see where your ACPI interrutps come from...
Initial WMI support -- Windows can run, but it can't hide...
video/brightness continues to mature...
cpuidle is now default enabled on ACPI configs
a bunch of bug fixes

This will update the files shown below.

thanks!

-Len

ps. individual patches are available on linux-acpi@vger.kernel.org
and a consolidated plain patch is available here:

        This patch contains the following possible cleanups:
        - make the following needlessly global code static:
          - drivers/acpi/bay.c:dev_attr_eject
          - drivers/acpi/bay.c:dev_attr_present
          - drivers/acpi/dock.c:dev_attr_docked
          - drivers/acpi/dock.c:dev_attr_flags
          - drivers/acpi/dock.c:dev_attr_uid
          - drivers/acpi/dock.c:dev_attr_undock
          - drivers/acpi/pci_bind.c:acpi_pci_unbind()
          - drivers/acpi/pci_link.c:acpi_link_lock
          - drivers/acpi/sbs.c:acpi_sbs_callback()
          - drivers/acpi/sbshc.c:acpi_smbus_transaction()
          - drivers/acpi/sleep/main.c:acpi_sleep_prepare()
        - #if 0 the following unused global functions:
          - drivers/acpi/numa.c:acpi_unmap_pxm_to_node()
        - remove the following unused EXPORT_SYMBOL's:
          - acpi_register_gsi
          - acpi_unregister_gsi
          - acpi_strict

    acpi_safe_halt() also does not enable interrupts on all return paths.

    ACPI: track opregion names to avoid driver resource conflicts.
    
    Small ACPICA extension to be able to store the name of operation regions in osl.c later
    
    In ACPI, AML can define accesses to IO ports and System Memory by Operation
    Regions.  Those are not registered as done by PNPACPI using resource templates
    (and _CRS/_SRS methods).
    
    The IO ports and System Memory regions may get accessed by arbitrary AML code.
     When native drivers are accessing the same resources bad things can happen
    (e.g.  a critical shutdown temperature of 3000 C every 2 months or so).
    
    It is not really possible to register the operation regions via
    request_resource, as they often overlap with pnp or other resources (e.g.
    statically setup IO resources below 0x100).
    
    This approach stores all Operation Region declarations (IO and System Memory
    only) at ACPI table parse time.  It offers a similar functionality like
    request_region and let drivers which are known to possibly use the same IO
    ports and Memory which are also often used by ACPI (hwmon and i2c) check for
    ACPI interference.
    
    A boot parameter acpi_enforce_resources=strict/lax/no is provided, which
    is default set to lax:
      - strict: let conflicting drivers fail to load with an error message
      - lax:    let conflicting driver work normal with a warning message
      - no:     no functional change at all
    Depending on the feedback and the kind of interferences we see, this
    should be set to strict at later time.
    
    Goal of this patch set is:
      - Identify ACPI interferences in bug reports (very hard to reproduce
        and to identify)
      - Find BIOSes for that an ACPI driver should exist for specific HW
        instead of a native one.
      - stability in general
    
    Provide acpi_check_{mem_}region.
    
    Drivers can additionally check against possible ACPI interference by also
    invoking this shortly before they call request_region.
    If -EBUSY is returned, the driver must not load.
    Use acpi_enforce_resources=strict/lax/no options to:
      - strict: let conflicting drivers fail to load with an error message
      - lax:    let conflicting driver work normal with a warning message
      - no:     no functional change at all

    ACPI: basic initramfs DSDT override support
    
    The basics of DSDT from initramfs. In case this option is selected,
    populate_rootfs() is called a bit earlier to have the initramfs content
    available during ACPI initialization.
    
    This is a very similar path to the one available at
    http://gaugusch.at/kernel.shtml but with some update in the
    documentation, default set to No and the change of populate_rootfs() the
    "Jeff Mahony way" (which avoids reading the initramfs twice).

    ACPI: WMI: Add ACPI-WMI mapping driver
    
    The following is an implementation of the Windows Management
    Instrumentation (WMI) ACPI interface mapper (PNP0C14).
    
    What it does:
    
    Parses the _WDG method and exports functions to process WMI method calls,
    data block query/ set commands (both based on GUID) and does basic event
    handling.
    
    How: WMI presents an in kernel interface here (essentially, a minimal
    wrapper around ACPI)
    
    (const char *guid assume the 36 character ASCII representation of
    a GUID - e.g. 67C3371D-95A3-4C37-BB61-DD47B491DAAB)
    
    wmi_evaluate_method(const char *guid, u8 instance, u32 method_id,
    const struct acpi_buffer *in, struct acpi_buffer *out)
    
    wmi_query_block(const char *guid, u8 instance,
    struct acpi_buffer *out)
    
    wmi_set_block(const char *guid, u38 instance,
    const struct acpi_buffer *in)
    
    wmi_install_notify_handler(acpi_notify_handler handler);
    
    wmi_remove_notify_handler(void);
    
    wmi_get_event_data(u32 event, struct acpi_buffer *out)
    
    wmi_has_guid(const char guid*)
    
    wmi_has_guid() is a helper function to find if a GUID exists or not on the
    system (a quick and easy way for WMI dependant drivers to see if the
    the method/ block they want exists, since GUIDs are supposed to be unique).
    
    Event handling - allow a WMI based driver to register a notifier handler
    for each GUID with WMI. When a notification is sent to a GUID in WMI, the
    handler registered with WMI is then called (it is left to the caller to
    ask for the WMI event data associated with the GUID, if needed).
    
    What it won't do:
    
    Unicode - The MS article[1] calls for converting between ASCII and Unicode (or
    vice versa) if a GUID is marked as "string". This is left up to the calling
    driver.
    
    Handle a MOF[1] - the WMI mapper just exports methods, data and events to
    userspace. MOF handling is down to userspace.
    
    Userspace interface - this will be added later.

    ===
    ChangeLog
    ==
    
    v1 (2007-10-02):
    
    * Initial release
    
    v2 (2007-10-05):
    
    * Cleaned up code - split up super "wmi_evaluate_block" -> each external
      symbol now handles its own ACPI calls, rather than handing off to
      a "super" method (and in turn, is a lot simpler to read)
    * Added a find_guid() symbol - return true if a given GUID exists on
      the system
    * wmi_* functions now return type acpi_status (since they are just
      fancy wrappers around acpi_evaluate_object())
    * Removed extra debug code
    
    v3 (2007-10-27)
    
    * More code clean up - now passes checkpatch.pl
    * Change data block calls - ref MS spec, method ID is not required for
      them, so drop it from the function parameters.
    * Const'ify guid in the function call parameters.
    * Fix _WDG buffer handling - copy the data to our own private structure.
    * Change WMI from tristate to bool - otherwise the external functions are
      not exported in linux/acpi.h if you try to build WMI as a module.
    * Fix more flag comparisons.
    * Add a maintainers entry - since I wrote this, I should take the blame
      for it.
    
    v4 (2007-10-30)
    
    * Add missing brace from after fixing checkpatch errors.
    * Rewrote event handling - allow external drivers to register with WMI to
      handle WMI events
    * Clean up flags and sanitise flag handling
    
    v5 (2007-11-03)
    
    * Add sysfs interface for userspace. Export events over netlink again.
    * Remove module left overs, fully convert to built-in driver.
    * Tweak in-kernel API to use u8 for instance, since this is what the GUID
      blocks use (so instance cannot be greater than u8).
    * Export wmi_get_event_data() for in kernel WMI drivers.
    
    v6 (2007-11-07)
    
    * Split out userspace into a different patch
    
    v7 (2007-11-20)
    
    * Fix driver to handle multiple PNP0C14 devices - store all GUIDs using
      the kernel's built in list functions, and just keep adding to the list
      every time we handle a PNP0C14 devices - GUIDs will always be unique,
      and WMI callers do not know or care about different devices.
    * Change WMI event handler registration to use its' own event handling
      struct; we should not pass an acpi_handle down to any WMI based drivers
      - they should be able to function with only the calls provided in WMI.
    * Update my e-mail address
    
    v8 (2007-11-28)
    
    * Convert back to a module.
    * Update Kconfig to default to building as a module.
    * Remove an erroneous printk.
    * Simply comments for string flag (since we now leave the handling to the
      caller).
    
    v9 (2007-12-07)
    
    * Add back missing MODULE_DEVICE_TABLE for autoloading
    * Checkpatch fixes
    
    v10 (2007-12-12)
    
    * Workaround broken GUIDs declared expensive without a WCxx method.
    * Minor cleanups
    
    v11 (2007-12-17)
    
    * More fixing for broken GUIDs declared expensive without a WCxx method.
    * Add basic EmbeddedControl region handling.
    
    v12 (2007-12-18)
    
    * Changed EC region handling code, as per Alexey's comments.
    
    v13 (2007-12-27)
    
    * Changed event handling so that we can have one event handler registered
      per GUID, as per Matthew Garrett's suggestion.
    
    v14 (2008-01-12)
    
    * Remove ACPI debug statements
    
    v15 (2008-02-01)
    
    * Replace two remaining 'x == NULL' type tests with '!x'
    
    v16 (2008-02-05)
    
    * Change MAINTAINERS entry, as I am not, and never have been, paid to work
      on WMI
    * Remove 'default' line from Kconfig

    ACPI: Update the t-state for every affected cpu when t-state is changed
    
    According to ACPI spec, the _TSD object provides T-state control cross
    logical processor dependency information to OSPM. So the t-state
    coordination should be considered when T-state for one cpu is changed.
    
    According to ACPI spec, three types of coordination are defined.
    SW_ALL, SW_ANY and HW_ALL.
    
    SW_ALL: it means that OSPM needs to initiate T-state transition on
    all processors in the domain. It is necessary to call throttling set function
    for all affected cpus.
    
    SW_ANY: it means that OSPM may initiate T-state transition on any processor in
    the domain.
    
    HW_ALL: Spec only says that hardware will perform the coordination and doesn't
    recommend how OSPM coordinate T-state among the affected cpus. So it is treated
    as the type of SW_ALL. It means that OSPM needs to initiate t-state transition
    on all the processors in the domain.

    ACPI : Add T-state event notifier function
    
    The t-state coordination should be considered when T-state for one cpu
    is changed.It means that OSPM should select one proper target T-state for
    the all affected cpus before updating T-state.
    
    So the function of acpi_processor_throttling_notifier is added.
    Before updating T-state it can be called for all  the affected cpus to get
    the proper target T-state, which can meet the requirement of thermal, user and
    _TPC. After updating T-state, it can be called to update T-state flag.

    ACPI : Update T-state coordination after getting _TSD info
    
    Accordint to ACPI spec, the _TSD object provides T-state control cross
    logical processor dependency information to OSPM.
    After the _TSD data for all cpus are obtained, OSPM will set up
    the T-state coordination between CPUs.
    
    Of course if the _TSD doesn't exist or _TSD data is incorrect , it is
    assumed that there is no T-state coordination and T-state is changed
    independently.
    
    Now there is no proper solution to update T-state coordination after
    one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

    Vendors often ship machines with a choice of integrated or discrete

    module will locate devices that may not exist on this specific platform.
    Attempt to determine whether the device exists or not, and abort the
    device creation if it doesn't.

    ACPI: register ACPI Processor as generic thermal cooling device
    
    Register ACPI processor as thermal cooling devices.
    A combination of processor T-state and P-state are used for thermal throttling.
    the processor will reduce the frequency first and then set the T-state.
    
    we use cpufreq_thermal_reduction_pctg to calculate the cpufreq limit,
    and call cpufreq_verify_with_limit to set the cpufreq limit.
    if cpufreq driver is loaded, then we have four cooling state for cpufreq control.
    cooling state 0: cpufreq limit == max_freq
    cooling state 1: cpufreq limit == max_freq * 80%
    cooling state 2: cpufreq limit == max_freq * 60%
    cooling state 3: cpufreq limit == max_freq * 40%
    
    after the cpufreq limit is set to 40 percentage of the max_freq,
    we use T-state for cooling.
    
    eg. a processor has P-state support, and it has 8 T-state (T0-T7),
    the max_state of the proceesor is 10:
    
    state	cpufreq-limit  T-state
    0:	max_freq	T0
    1:	max_freq * 80%	T0
    2:	max_freq * 60%	T0
    3:	max_freq * 40%	T0
    4:	max_freq * 40%	T1
    5:	max_freq * 40%	T2
    6:	max_freq * 40%	T3
    7:	max_freq * 40%	T4
    8:	max_freq * 40%	T5
    9:	max_freq * 40%	T6
    10:	max_freq * 40%	T7

    re-evaluate _PSV and _ACx methods upon notification 0x81
    re-evaluate _PSL and _ALx and _TZD upon notificaiton 0x82.
    But the current code re-evaluates all the trip points for 0x81 while
    only re-evaluates _TZD for 0x82.
    
    Fix this violation of ACPI spec.
    
    TODO: devices in _PSL, _ALx and _TZD may change after a notification 0x82.

    The sysfs backlight class provides no mechanism for querying the

    we can't provide that information to userspace, instead collapse the

    ACPI: thinkpad-acpi: wakeup on hotunplug reporting
    
    Handle some HKEY events that the firmware uses to report the reason for a
    wake up, and to also notify that the system could go back to sleep (if it
    woke up just to eject something from the bay, or to undock).
    
    The driver will report the reason of the last wake up in the sysfs
    attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up
    event", 1 for "bay ejection request" and 2 for "undock request".
    
    The firmware will also report if the operation that triggered the wake up
    has been completed, by issuing an HKEY 0x3003 or 0x4003 event.  If the
    operation fails, no event is sent.  When such a hotunplug sucessfull
    notification is issued, the driver sets the attribute
    "wakeup_hotunplug_complete" to 1.
    
    While the firmware does tell us whether we are waking from a suspend or
    hibernation scenario, the Linux way of hibernating makes this information
    not reliable, and therefore it is not reported.
    
    The idea is that if any of these attributes are non-zero, userspace might
    want to do something at the end of the "wake up from sleep" procedures,
    such as offering to send the machine back into sleep as soon as it is safe
    to do so.

    ACPI: thinkpad-acpi: add CMOS NVRAM polling for hot keys (v9)
    
    Older ThinkPad models do not export some of the hot keys over the
    event-based ACPI hot key interface.  For these models, one has to poll
    the CMOS NVRAM to check the key state at a rate faster than the expected
    rate at which the user might repeatedly press the same hot key.
    
    This patch implements this functionality for many of the hotkeys in a
    transparent way: hot keys will now Just Work, and the driver knows the
    best approach (events or NVRAM polling) to employ, based on the
    HKEY.MHKA ACPI method.
    
    Also, the driver can turn off the polling when there are no users for
    the hot keys that need such polling.
    
    The NVRAM-based hot keys of the A3x series that have never been
    implemented by later models are not supported, to avoid changes in the
    keymap of the input devices that could cause headaches in the future.
    
    There is a Kconfig option to avoid compiling the NVRAM polling code, as
    it is not very small, and unlikely to be useful on any ThinkPad newer
    than a T40, X31 or R52.
    
    This feature is based on a previous effort by Richard Hughes.

    ACPI: thinkpad-acpi: refactor hotkey_get and hotkey_set (v2)
    
    Refactor and organize the code a bit for the NVRAM polling support:
    
    1. Split hotkey_get/set into hotkey_status_get/set and hotkey_mask_get/set;
    2. Cache the status of hot key mask for later driver use;
    3. Make sure the cache of hot key mask is refreshed when needed;
    4. log a printk notice when the firmware doesn't set the hot key
       mask to exactly what we asked it to;
    5. Add proper locking to the data structures.
    
    Only (4) should be user-noticeable, but there is a chance (5) fixes
    some unknown/unreported race conditions.

    Publish the requirements for keymap changes.  This is a documentation

    Currently, people look at the thinkpad-acpi default keymaps, and think:
    "modifying this is a trivial thing, it can't break systems, and there are
    keys defined for foo and bar, but the driver has them as KEY_RESERVED.
    Must have been an oversight, let me change it."
    
    And since they never get to see the bug reports, because they are not
    really a part of the Linux ThinkPad users community (linux-thinkpad
    mailinglist, thinkwiki wiki, thinkpad forums) and laptop users are slow
    to complain to distros about any breakages...

    big sec, min, hr, mo, day and yr are counted twice to get reasonable

    In additon, /proc/acpi/alarm can set a related value which can be
    specified as YYYY years MM months DD days HH hours MM minutes SS
    senconds, it isn't a date, so you can specify as +0000-00-00 96:00:00

    ACPI: tables: complete searching upon RSDP w/ bad checksum.
    
    ACPI tables follow a tree structure in memory.
    The root of the tree is the RSDP (Root System Description Pointer).
    
    To find the RSDP, the OS searches for the signature "RSD PTR "
    in well known physical memory locations.  Then the OS computes
    a table checksum to verify that the signature is really part
    of a valid table header.
    
    Some systems have a proper signature but an invalid checksum;
    followed elsewhere by a proper signature with valid checksum.
    
    http://bugzilla.kernel.org/show_bug.cgi?id=9444
    
    The Linux RSDP scanning code bailed out on those systems
    and as a result they booted with ACPI disabled.
    
    Fix this by deleting the Linux RSDP scanning code and
    plugging in the ACPICA RSDP scanning code.

    cpuidle: default processor.latency_factor=2
    
    More aggressively request deep C-states.
    
    Note that the job of the OS is to minimize latency
    impact to expected break events such as interrupts.
    
    It is not the job of the OS to try to calculate if
    the C-state will reach energy break-even.
    The platform doesn't give the OS enough information
    for it to make that calculation.  Thus, it is up
    to the platform to decide if it is worth it to
    go as deep as the OS requested it to, or if it
    should internally demote to a more shallow C-state.
    
    But the converse is not true.  The platform can not
    promote into a deeper C-state than the OS requested
    else it may violate latency constraints.  So it is
    important that the OS be aggressive in giving the
    platform permission to enter deep C-states.

    Level GPE should not be enabled until all work caused by it is done,
    e.g. all Notify() methods are completed.
    This can be accomplished by appending enable_gpe function to the end
    of notify queue.

    Revert "speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1"
    
    For P4 model < 2, The MSR_FBC_REGISTER_ID ratio is undefined.
    Revert the commit that was added to handle that case,
    as it results in random MHz displayed.  Something else will
    have to be done to properly handle model < 2.

    //    [PATCH] speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1
    //
    //    The Pentium4 models 0&1 have a longer MSR_EBC_FREQUENCY_ID register as the
    //    models 2&3, so the bit shift must be bigger.

    ACPI: disable stray GPE, prevent ACPI interrupt storm
    
    GPEs are disabled depending on their type --
    WAKE, WAKE_RUN, and RUNTIME.  An error is returned
    if we are asked to disable a GPE that has no type.
    
    But at least one system exists that enables a GPE from AML
    that is not the EC GPE, and has no _Lxx/_Exx AML handler,
    and is thus never initialized.
    
    In this case, when an external CRT is plugged in,
    the GPE fires, we attempt to disable the GPE,
    but instead just return an error.
    So the GPE stays asserted and an ACPI interrupt storm follows.
    
    The fix is to disable a firing GPE,
    even if it comes from outer space.

    ACPI: CONFIG_CPU_IDLE=ACPI by default
    
    In Linux-2.6.24, CPU_IDLE went upstream, default =n.
    For Linux-2.6.25, enable it by default on ACPI systems.
    For Linux-2.6.26, we plan to enable it always on ACPI systems.

    ACPI: add control method tracing support
    
    Add debug tracing support during certain AML method execution.
    
    Four more module parameters are created under /sys/module/acpi/parameters/:
    trace_method_name:	the AML method name that user wants to trace
    
    trace_debug_layer:	the temporary debug_layer used when tracing the method.
    			Using 0xffffffff by default if it is 0.
    
    trace_debug_level:	the temporary debug_level used when tracing the method.
    			Using 0x00ffffff by default if it is 0.
    
    trace_state:		The status of the tracing feature.
    			"enabled" means this feature is enabled
    			and the AML method is traced every time it's executed.
    			"1" means this feature is enabled and the AML method
    			will only be traced during the next execution.
    			"disabled" means this feature is disabled.
    			Users can enable/disable this debug tracing feature by
    			"echo string > /sys/module/acpi/parameters/trace_state".
    			"string" should be one of "enable", "disable" and "1".
