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...

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.

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.

It adds wireless radio and bluetooth control, and on some laptops, exposes the mail LED and LCD backlight. v1: * Initial release v2: * Replace left over ACPI references with WMI * Add GUID based autoloading (depends on future work to WMI) * Add DMI based autoloading (backup solution until WMI sysfs/ class work is available) * Checkpatch fixes v3: * Add new EC quirks for Aspire 3100 & 5100, and Extensa 5220 v4: * Simplified internal handling of WMID and AMW0 devices * Add autodetection for bluetooth and maximum brightness on AMW0 V2 and WMID laptops. v5: * Add EC quirk for Medion MD 98000 * Add autodetection for AMW0, and mail LED on AMW0 and AMW0 V2. * Improve error handling * Fix AMW0 V2 bluetooth and wireless, by using both WMID and AMW0 methods to ensure that the correct value is always set. v6: * Fix 'use before initialisation' bug with quirks. v7 * Fix bug on AMW0 where acer-wmi would exit if a mail LED was not detected. * Add Acer Aspire 9110 mail LED support * Fix section mismatch warnings Signed-off-by: Carlos Corbacho CC: Matthew Garrett Signed-off-by: Len Brown --- drivers/misc/Kconfig | 16 + drivers/misc/Makefile | 1 + drivers/misc/acer-wmi.c | 1109 +++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 1126 insertions(+) create mode 100644 drivers/misc/acer-wmi.c (limited to 'drivers/misc') diff --git a/drivers/misc/Kconfig b/drivers/misc/Kconfig index b5e67c0ff43..35d2c22c5d2 100644 --- a/drivers/misc/Kconfig +++ b/drivers/misc/Kconfig @@ -92,6 +92,22 @@ config TIFM_7XX1 To compile this driver as a module, choose M here: the module will be called tifm_7xx1. +config ACER_WMI + tristate "Acer WMI Laptop Extras (EXPERIMENTAL)" + depends on X86 + depends on EXPERIMENTAL + depends on ACPI + depends on ACPI_WMI + depends on LEDS_CLASS + depends on BACKLIGHT_CLASS_DEVICE + ---help--- + This is a driver for newer Acer (and Wistron) laptops.
