* classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliasesThadeu Lima de Souza Cascardo2010-04-01
| | | | | | | | | | | | | | | | commit 02e77a55f7b7e36888e39c62439fedb90ae4e808 upstream. Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we create a table containing all ids to export to get a module alias for each one. This will fix automatic loading of the driver when one of the ACPI devices is not present (like the accelerometer, which is not present in some models).

* thinkpad-acpi: lock down video output state accessHenrique de Moraes Holschuh2010-03-15
| | | | | | | | | | | | | | | | | | | | | commit b525c06cdbd8a3963f0173ccd23f9147d4c384b5 upstream. Given the right combination of ThinkPad and X.org, just reading the video output control state is enough to hard-crash X.org. Until the day I somehow find out a model or BIOS cut date to not provide this feature to ThinkPads that can do video switching through X RandR, change permissions so that only processes with CAP_SYS_ADMIN can access any sort of video output control state. This bug could be considered a local DoS I suppose, as it allows any non-privledged local user to cause some versions of X.org to hard-crash some ThinkPads.

* thinkpad-acpi: fix bluetooth/wwan resumeHenrique de Moraes Holschuh2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | commit 08fedfc903c78e380b0baa7b57c52d367794d0a5 upstream. Studying the DSDTs of various thinkpads, it looks like bit 3 of the argument to SBDC and SWAN is not "set radio to last state on resume". Rather, it seems to be "if this bit is set, enable radio on resume, otherwise disable it on resume". So, the proper way to prepare the radios for S3 suspend is: disable radio and clear bit 3 on the SBDC/SWAN call to to resume with radio disabled, and enable radio and set bit 3 on the SBDC/SWAN call to resume with the radio enabled. Also, for persistent devices, the rfkill core does not restore state, so we really need to get the firmware to do the right thing. We don't sync the radio state on suspend, instead we trust the BIOS to not do anything weird if we never touched the radio state since boot. Time will tell if that's a wise way of doing things...

* thinkpad-acpi: make driver events work in NVRAM poll modeHenrique de Moraes Holschuh2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | commit 7f0cf712a74fcc3ad21f0bde95bd32c2f2cc3888 upstream. Thadeu Lima de Souza Cascardo reports this: Brightness notification does not work until the user writes to hotkey_mask attribute. That's because the polling thread will only run if hotkey_user_mask is set and someone is reading the input device or if hotkey_driver_mask is set. In this second case, this condition is not tested after the mask is changed, because the brightness and volume drivers are started after the hotkey drivers. Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so that the poller kthread will be started when needed.

* thinkpad-acpi: document HKEY event 3006Henrique de Moraes Holschuh2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | | commit bf8b29c8f7f8269e99eca8b19048ed5b34b51810 upstream. Event 0x3006 is used to help power management of the ODD in the UltraBay. The EC generates this event when the ODD eject button is pressed (even if the bay is powered down). Normally, Linux doesn't need this as we keep the SATA link powered up (which wastes power). The EC powers up the bay by itself when the ODD eject button is pressed, and the SATA PHY reports the hotplug. However, we could also power that SATA link down (and for that matter, also power down the Ultrabay) if the ODD is left idle for a while with no disk inside, and use event 0x3006 to know when we need that SATA link powered back up. For now, just stop asking for more information when event 0x3006 is seen, there is no point in pestering users about it anymore.

Clemens Ladisch reports that thinkpad-acpi improperly implements the ALSA API, and always returns 0 for success for the "put" callbacks while the API requires it to return "1" when the control value has been changed in the hardware/firmware.

* | eeepc-laptop: disable cpu speed control on EeePC 701Alan Jenkins2010-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EeePC 4G ("701") implements CFVS, but it is not supported by the pre-installed OS, and the original option to change it in the BIOS setup screen was removed in later versions. Judging by the lack of "Super Hybrid Engine" on Asus product pages, this applies to all "701" models (4G/4G Surf/2G Surf). So Asus made a deliberate decision not to support it on this model. We have several reports that using it can cause the system to hang [1]. That said, it does not happen all the time. Some users do not experience it at all (and apparently wish to continue "right-clocking"). Check for the EeePC 701 using DMI. If met, then disable writes to the "cpufv" sysfs attribute and log an explanatory message. Add a "cpufv_disabled" attribute which allow users to override this policy. Writing to this attribute will log a second message. The sysfs attribute is more useful than a module option, because it makes it easier for userspace scripts to provide consistent behaviour (according to user configuration), regardless of whether the kernel includes this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vaio Type X and possibly other new models use F135 as the radio frequency controlling function attached to the SNC device. In the indexed table this corresponds to 0x0135 (surpise!). Signed-off-by: Mattia Dongili <malattia@linux.it> Signed-off-by: Len Brown <len.brown@intel.com>
