* ACPI: thinkpad-acpi: add poll() support to some sysfs attributesHenrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | Implement poll()/select() support through sysfs_notify() for some key attributes which userspace might want to poll() or select() on. In order to let userspace know poll()/select() support is available for an attribute, the thinkpad-acpi sysfs interface version is also bumped up. Further changes that add poll()/select() capabilities to any pre-existing attributes will also increment the sysfs interface version.

* ACPI: thinkpad-acpi: silence _sta warningHenrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | When both CONFIG_THINKPAD_ACPI_DOCK and CONFIG_THINKPAD_ACPI_BAY are undefined, _sta is not used and that causes a gcc warning. Fix it (and I think this is a regression, I am pretty sure I fixed this once before, sorry about that). Issue reported by: Pritt Laes.

* ACPI: thinkpad-acpi: wakeup on hotunplug reportingHenrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: cleanup hotkey_notify and HKEY log messagesHenrique de Moraes Holschuh2008-02-01

Also, document event 0x5010 (brightness changed notification) and do not log it as an unknown event (even if we do not use it for anything right now).

* ACPI: thinkpad-acpi: bump up version to 0.18Henrique de Moraes Holschuh2008-02-01

* ACPI: thinkpad-acpi: add CMOS NVRAM polling for hot keys (v9)Henrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)Henrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | | | | | 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.

* ACPI: thinkpad-acpi: document keymap gotcha's (v2)Henrique de Moraes Holschuh2008-02-01
| | | | | | | | | | | | | | | | | | Publish the requirements for keymap changes. This is a documentation change, only. 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...
