Anyway, this completes the ACPICA changes we started for this release. The bulk of the platform driver updates should be in here, though I do expect some smaller updates still. I also expect some ACPI bug fixes which are now percolating. This will update the files shown below. thanks! -- Len Brown Intel Open Source Technology Center ps. individual patches are available on linux-acpi@vger.kernel.org and a consolidated plain patch is available here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/2.6.32/acpi-release-20091214-2.6.32.diff.gz Documentation/acpi/method-customizing.txt | 66 ++ Documentation/feature-removal-schedule.txt | 19 + Documentation/laptops/thinkpad-acpi.txt | 114 ++- Documentation/thermal/sysfs-api.txt | 1 + arch/x86/kernel/acpi/cstate.c | 2 +- drivers/acpi/acpi_pad.c | 3 +- drivers/acpi/acpica/acnamesp.h | 9 +- drivers/acpi/acpica/acobject.h | 6 +- drivers/acpi/acpica/dsmethod.c | 2 +- drivers/acpi/acpica/dswload.c | 64 +- drivers/acpi/acpica/evregion.c | 4 +- drivers/acpi/acpica/evrgnini.c | 15 + drivers/acpi/acpica/evxface.c | 4 +- drivers/acpi/acpica/evxfevnt.c | 4 +- drivers/acpi/acpica/evxfregn.c | 4 +- drivers/acpi/acpica/exmutex.c | 18 +- drivers/acpi/acpica/nsaccess.c | 2 +- drivers/acpi/acpica/nsdump.c | 2 +- drivers/acpi/acpica/nseval.c | 18 + drivers/acpi/acpica/nsnames.c | 2 +- drivers/acpi/acpica/nspredef.c | 93 +-- drivers/acpi/acpica/nsrepair.c | 447 ++++++++-- drivers/acpi/acpica/nsrepair2.c | 195 +++- drivers/acpi/acpica/nsutils.c | 57 +- drivers/acpi/acpica/nsxfeval.c | 10 +- drivers/acpi/acpica/nsxfname.c | 10 +- drivers/acpi/acpica/nsxfobj.c | 14 +- drivers/acpi/acpica/psxface.c | 3 +- drivers/acpi/acpica/rsxface.c | 2 +- drivers/acpi/acpica/utcopy.c | 27 +- drivers/acpi/battery.c | 2 +- drivers/acpi/bus.c | 148 +++ drivers/acpi/button.c | 7 + drivers/acpi/debug.c | 84 ++- drivers/acpi/dock.c | 261 ++---- drivers/acpi/fan.c | 2 +- drivers/acpi/numa.c | 21 +- drivers/acpi/osl.c | 2 +- drivers/acpi/pci_root.c | 76 +-- drivers/acpi/processor_core.c | 10 +- drivers/acpi/processor_idle.c | 11 +- drivers/acpi/processor_perflib.c | 50 +- drivers/acpi/thermal.c | 7 + drivers/char/ipmi/ipmi_si_intf.c | 118 +++- drivers/misc/Kconfig | 13 -

The RFKill switch brute force pulls out the USB device when flipped to 'off', but it doesn't automatically re-enable it. Without this driver, the Bluetooth is gone until after a reboot on my Portege R500.

It can be enabled at module load time by a module parameter (volume_control=1). The audio control mixer that thinkpad-acpi interacts with is fully functional without any drivers, and operated by hotkeys. The idea behind the console audio control is that the human operator is the only one that can interact with it. The ThinkVantage suite in Windows does not allow any software-based overrides, and only does OSD (on-screen-display) functions. The Linux driver will, with the addition of the ALSA interface, try to follow and enforce the ThinkVantage UI design: The user is supposed to use the keyboard hotkeys to interact with the console audio control. The kernel and the desktop environment is supposed to cooperate to provide proper user feedback through on-screen-display functions. Distros are urged to not to enable volume control by default. Enabling this must be a local admin's decision. This is the reason why there is no Kconfig option. Keep in mind that all ThinkPads have a normal, main mixer (AC97 or HDA) for regular software-based audio control. We are not talking about that mixer here. Advanced users are, of course, free to enable volume control and do as they please.

Newer Lenovo models only have the mute gate function, and leave the volume control to the HDA mixer. Until a way to automatically query the firmware about its audio control capabilities is discovered (there might not be any), use a white/black list. We will likely need to ask T60 (old and new model) and Z60/Z61 users whether they have volume control to populate the black/white list. Meanwhile, provide a volume_capabilities parameter that can be used to override the defaults.

Change the driver to stop issuing SMIs, and just drive the EC directly to the desired level (DSDTs seem to confirm this will work even on very old models like the 570 and 600e/x). We checkpoint directly to NVRAM (this can be turned off) at suspend/shutdown/driver unload, which from what I can see in tbp, should also work on every ThinkPad.

Also, a new ACPI-WMI event type (called KeyIDList) with a value of 0x0010 is defined. Any BIOS containing 0xB2 table will send hotkey notifications using KeyIDList event. This is Rezwanul's patch, updated to ensure that brightness events are not sent if the backlight is controlled via ACPI and with the default keycode for the display output switching altered to match desktop expectations.

Instead, they should extract the data they need either from a "driver data" parameter, or the "driver data" field of the object which they operate on. The "eeepc" variable can then be removed. In practice, drivers under "drivers/platform" can get away without using driver data, because it doesn't make sense to have more than one instance of them. However this makes it harder to review them for correctness. This is especially true for core ACPI developers who have not previously been exposed to this anti-pattern :-). This will serve as an example of best practice for new driver writers (whether they find it themselves, or have it pointed out during review :-). The hwmon sub-device is a special case. It uses ec_{read,write} which are defined to communicate with the (first) EC, so it does not require any driver data. It should still only be instantiated in the context of an ASUS010 device because we don't have a safe way to probe for it.

Replace the "hotk" names used throughout the driver with some slightly more appropriate names. The actual strings used in kernel messages and sysfs are left unchanged. e.g. EEEPC_HOTK_FILE -> EEEPC_LAPTOP_FILE EEEPC_HOTK_HID -> EEEPC_ACPI_HID eeepc_hotk_notify -> eeepc_acpi_notify struct eeepc_hotk -> struct eeepc_laptop ehotk -> eeepc I'm about to refactor the entire driver to remove the global "ehotk" variable, and I don't wish to add "struct eeepc_hotk *ehotk" to functions which have nothing to do with hotkeys. Also - fix the name of "eepc_get_entry_by_keycode()" - remove the unused definition of NOTIFY_WLAN_ON.

Move e.g. backlight_ops to follow the functions it refers to, and remove the forward declarations. The code itself should remain unchanged.

So for consistency it should use ec_read() to read values. The extra layers of indirection used did not add any value. This may mean we no longer take the ACPI global lock for such reads (if the EC operation region requires the lock and the EC does not). But there is no point locking each one-byte read individually, when write operations do not use the lock at all.

Fix eeepc_get_fan_ctrl() to return 2 for automatic fan control. Setting "1" for manual control is already consistent with the documentation, so this remains unchanged. Let's preserve the ABI for this specific driver, so that writing "0" will still invoke automatic control. (The documentation says setting "0" should leave the fan at full speed all the time. This mode is not directly supported by our hardware. Full speed is rather noisy on my 701 and the automatic control has never used it. If you really want this e.g. to prolong the life of an EeePC used as a server, you can always use manual mode. hwmon has always been fairly machine-specific, and you're in a tiny minority (or elite :-). I'm sure you're smart enough to notice that the fan doesn't turn on to full speed when you try this mode, either by ear or checking fan_input1. We could even claim to be honouring the spirit of the documentation. "0" really means "safe mode". EeePCs default to automatic mode, ie that is what Asus will actually test. Since we do not provide any way to tamper with the temperature threshold, automatic mode _is_ the safe option).

Change thinkpad-acpi to ask the firmware to resume with the radios in the last state. This fixes the Bluetooth and WWAN rfkill switches. Note that it means we respect the firmware's oddities. Should the user toggle the hardware rfkill switch on and off, it might cause the radios to resume enabled. UWB is an unknown quantity since it has nowhere the same level of firmware support (no control over state storage in NVRAM, for example), and might need further fixing. Testers welcome. This change fixes a regression from 2.6.30.

The current driver default was reported to not work at all. This bug can be worked around by the "brightness_mode=3" module parameter. Change the default of the R50e and R51 2xxx models (which use the same EC firmware, 1V) to TPACPI_BRGHT_Q_EC, but keep TPACPI_BRGHT_Q_ASK set for now, as I'd like to get more reports. This fixes a regression caused by commit 59fe4fe34d7afdf63208124f313be9056feaa2f4, "thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAM" Kernel 2.6.31 also needs this fix.

The _OST contains two arguments: The first is the PERFORMANCE notificatin event. The second is the status of _PPC object. OSPM will convey the _PPC evaluation status to the platform. Of course when the module parameter of "ignore_ppc" is added, OSPM won't evaluate the _PPC object. But it will call the _OST object. At the same time the _OST object will be evaluated only when the PERFORMANCE notification event is received.

It also gives the impression to the user that he can change the polling interval through proc, while in fact he can't. Also, unset passive_delay when the forced passive trip point is unbound to allow polling to be disabled.
