| | | | | | | | | | | Copying to local variable is actually not neccessary, if all we need to do is snprintf(). This also removes problem where devname could be missing zero termination.

* | Documenation/laptops: rename and update hpfall.cPali Rohár2014-07-122-16/+47
|/ | | | | | | | | | | | | | | | Dell kernel driver dell-smo8800 provides same freefall interface as hp_accel so program hpfall.c works also on Dell laptops. So rename it to freefall.c. Dell driver does not provide hp::hddprotect led so make sure that freefall.c works also if hp::hddprotect does not exist in sysfs. Additionally write info to syslog.

* to fix scancodes returned by sony-laptop driverJohn Hughes2012-03-201-0/+5
| | | | | | | | | | | | | | | | | | | | Fix scancodes returned by driver to match scancodes used to remap keys. (Before the patch FN/E returned scancode 0x1B, but to remap scancode 0x14 had to be used). The scancodes returned by the sony-laptop driver for function keys did not match the scancodes used to remap keys. Also, since the scancode was sent to the input subsystem after the mapped keysym the /lib/udev/keymap utility was confused about which scancode to report for which keysym. This patch fixes the driver so the correct scancode is shown for each key. It also adds to the documentation a description of where to find the scancodes.

* thinkpad-acpi: handle HKEY 0x4010, 0x4011 eventsHenrique de Moraes Holschuh2011-07-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle events 0x4010 and 0x4011 so that we do not pester users about them. These events report when the thinkpad is docked/undocked to a native hotplug dock (i.e. one that does not need ACPI handling, nor is represented in the ACPI device tree). Such docks are based on USB 2.0/3.0, and also work as port replicators. We really want a proper dock class to report these, or at least new input EV_SW events. Since it is not clear which one to use yet, keep reporting them as vendor-specific ThinkPad events. WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the vendor-specific events will be REMOVED as soon as generic events are made available (duplicate events are a big problem), with an appropriate update to the thinkpad-acpi sysfs/event ABI versioning. Userspace is already prepared to provide easy backwards compatibility for such changes when convenient to the distro (see acpi-fakekey). * Event 0x4010: docking to hotplug dock/port replicator * Event 0x4011: undocking from hotplug dock/port replicator Typical usecase would be to trigger display reconfiguration. Reports mention T410, T510, and series 3 docks/port replicators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle some user interface events from the newer Lenovo models. We are likely to do something smart with these events in the future, for now, hide the ones we are already certain about from the user and userspace both. * Events 0x6000 and 0x6005 are key-related. 0x6005 is not properly identified yet. Ignore these events, and do not report them. * Event 0x6040 has not been properly identified yet, and we don't know if it is important (looks like it isn't, but still...). Keep reporting it. * Change the message the driver outputs on unknown 0x6xxx events, as all recent events are not related to thermal alarms. Degrade log level from ALERT to WARNING. Thanks to all users who reported these events or asked about them in a number of mailing lists. Your help is highly appreciated, even if I did took a lot of time to act on them. For that I apologise. I will list those that identified the reasons for the events as "reported-by", and I apologise in advance if I leave anyone out: it was not done on purpose, I made the mistake of not properly tagging all event report emails separately, and might have missed some.

|/ | | | | | | | | | | | | | | | | | 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: disable volume controlHenrique de Moraes Holschuh2009-12-151-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disable volume control by default. 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.

| | | | | | | | | | | | | | | | | | | | Lenovo removed the extra mixer since the T61 and thereabouts. 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.

| | | | | | | | | | | | | | | | | | | I don't trust the coupled EC writes and SMI calls the current volume control code does very much, although it is exactly what the IBM DSDTs seem to do (they never do more than a single step though). 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.

Handle better the second-gen firmware, which has no HKEY mask support but does report FN+F3, FN+F4 and FN+F12 without the need for NVRAM polling. a) always make the mask-related attributes available in sysfs; b) use DMI quirks to detect the second-gen firmware; c) properly report that FN+F3, FN+F4 and FN+F12 are enabled, and available even on mask-less second-gen firmware; 2. Decouple the issuing of hotkey events towards userspace from their reception from the firmware. ALSA mixer and brightness event reporting support will need this feature. 3. Clean up the mess in the hotkey driver a great deal. It is still very convoluted, and wants a full refactoring into a proper event API interface, but that is not going to happen today. 4. Fully reset firmware interface on resume (restore hotkey mask and status). 5. Stop losing polled events for no good reason when changing the mask and poll frequencies. We will still lose them when the hotkey_source_mask is changed, as well as any that happened between driver suspend and driver resume. The hotkey subdriver now has the notion of user-space-visible hotkey event mask, as well as of the set of "hotkey" events the driver needs (because brightness/volume change reports are not just keypress reports in most ThinkPad models). With this rewrite, the ABI level is bumped to 0x020500 should userspace need to know it is dealing with the updated hotkey subdriver.
