* eeepc-wmi: never load if legacy device is enabledCorentin Chary2011-01-07
| | | | | | | | | | | | | | If legacy device (SB.ATKD - ASUS010) used by eeepc-laptop is enabled, don't allow eeepc-wmi to load because: - eeepc-laptop may be loaded, and can conflict with eeepc-wmi (they both try to register eeepc::touchpad led for example). - the WMI interface is inteded to be used when the OS is not detected as Win 7. And when this is the case, the ASUS010 device is disabled. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

* eeepc-wmi: add debugfs entriesCorentin Chary2011-01-07
| | | | | | | | | | | | | | eeepc-wmi/ - debugfs root directory dev_id - current dev_id ctrl_param - current ctrl_param devs - call DEVS(dev_id, ctrl_param) and print result dsts - call DSTS(dev_id) and print result DEVS and DSTS are the main functions used in eeepc-wmi, this will allow to test new features without patching the drivers.

| | | | | | | | | | wimax support is missing because I don't have any DSDT with WMI and wimax support. Most of the code comes from eeepc-laptop. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

* eeepc-wmi: rework eeepc_wmi_init and eeepc_wmi_exitCorentin Chary2011-01-07
| | | | | | | | | | | | | | | | | The old code was using platform_driver.probe to initialize eeepc_wmi context. That's a mistake because if probe fail, eeepc_platform_register() won't tell anyone, and chaos will happen. Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(), and try to use the static platform_device only in eeepc_wmi_init() and eeepc_wmi_exit() The code is now very similar to eeepc-laptop, except eeepc_laptop_add and eeepc_laptop_remove are called from acpi_driver, not module init/exit functions, but WMI doesn't provide such functionalities (yet ?).

* eeepc-wmi: Add cpufv sysfs interfaceChris Bagwell2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | eeepc-laptop provides a sysfs interface to read and control what it calls cpufv. When WMI is enabled, the ACPI interface changes slightly and becames a write-only control with 3 valid values. Expose cpufv again to allow for user space utils that can extended battery life noticably and come a little closer to parity with eeepc-laptop. Write-only is OK for most user space apps because read status was mostly used to prevent unneeded mode changes. Since this same check to ignore changes to same mode also exists in the DSDT then it was wasted ACPI call. acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's read support of cpufv for debugging things such as behaviour during resume. This patch was tested with EEE PC 1005PE by monitoring powertop output while writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of an 1201NL and comparing it to 1005PE's DSDT.

* eeepc-wmi: add additional hotkeysChris Bagwell2010-10-21
| | | | | | | | | | | | | Added 4 hotkeys using same keymap values as eeepc-latop. These are mousepad toggle, resolution change, screen off, and task manager. These were tested on 1005PE and are the Fn-F3, F4, F7, and F9, respectively. Also, added a new hot key for power toggles (Fn-Space on 1005PE) and is meant to drive cpufv interface from userspace.
