* eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary2011-03-281-0/+162
| | | | | | | | | | | | | | | | | | | New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.

* eeepc-wmi: serialize access to wmi methodCorentin Chary2011-03-281-6/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | \AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

* eeepc-wmi: add hotplug code for Eeepc 1000HCorentin Chary2011-03-281-1/+273
| | | | | | | | | | | | | | Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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 Bagwell2010-10-211-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
