* intel_ips: blacklist HP ProBook laptopsTakashi Iwai2012-07-23
| | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1026850 commit 88ca518b0bb4161e5f20f8a1d9cc477cae294e54 upstream. intel_ips driver spews the warning message "ME failed to update for more than 1s, likely hung" at each second endlessly on HP ProBook laptops with IronLake. As this has never worked, better to blacklist the driver for now.

* sony-laptop: Enable keyboard backlight by defaultJosh Boyer2012-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1002880 commit 6fe6ae56a7cebaebc2e6daa11c423e4692f9b592 upstream. When the keyboard backlight support was originally added, the commit said to default it to on with a 10 second timeout. That actually wasn't the case, as the default value is commented out for the kbd_backlight parameter. Because it is a static variable, it gets set to 0 by default without some other form of initialization. However, it seems the function to set the value wasn't actually called immediately, so whatever state the keyboard was in initially would remain. Then commit df410d522410e67660 was introduced during the 2.6.39 timeframe to immediately set whatever value was present (as well as attempt to restore/reset the state on module removal or resume). That seems to have now forced the light off immediately when the module is loaded unless the option kbd_backlight=1 is specified. Let's enable it by default again (for the first time).

We have several reports which says acer-wmi is loaded on ideapads and register rfkill for wifi which can not be unblocked.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no wifi rfkill capability, there are reports which says acer-wmi also block wireless on Thinkpad E520/E420.

* Platform: Detect samsung laptop quirk when initial level is zeroJohn Serock2011-12-12
| | | | | | | | | | | | | | | | | | | | | | | | This patch depends on the "Platform: Brightness quirk for samsung laptop driver" patch from Jason Stubbs. This patch adds a check for an initial brightness level of 0; if the level is 0, this patch changes the brightness level to 1 before the driver attempts to detect the brightness quirk. The Samsung N150 netbook experiences the brightness quirk. Without Jason's patch, the only brightness levels available on the N150 are 0, 1, and 8. This patch ensures that, when the initial brightness level is 0, the samsang-laptop driver detects the brightness quirk on the N150, thereby making brightness levels 0 through 8 available.

* Platform: Brightness quirk for samsung laptop driverJason Stubbs2011-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | On some Samsung laptops the brightness regulation works slightly different. All SABI commands except for set_brightness work as expected. The behaviour of set_brightness is as follows: - Setting a new brightness will only step one level toward the new brightness level. For example, setting a level of 5 when the current level is 2 will result in a brightness level of 3. - A spurious KEY_BRIGHTNESS_UP or KEY_BRIGHTNESS_DOWN event is also generated along with the change in brightness. - Neither of the above two issues occur when changing from/to brightness level 0. This patch adds detection and a non-intrusive workaround for the above issues.

The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7. This patch fixes the above issue as well as a miscalculation that would occur in the case of min_brightness > 1.

* thinkpad-acpi: handle HKEY 0x4010, 0x4011 eventsHenrique de Moraes Holschuh2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* acer-wmi: Only update rfkill status for associated hotkey eventsSeth Forshee2011-07-07
| | | | | | | | | | | | acer-wmi is indiscriminately using the device state from hotkey events to update the various rfkill states. On the Aspire 1830 this can result in a soft block on the wlan when the touchpad hotkey is pressed, as it is reporting a non-zero device state that does not reflect the wireless status. To fix this, only update rfkill states when a wlan or bluetooth hotkey is pressed. Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
