| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This warning confuses users, who think it is an error. Not detecting the mail LED simply means it isn't there, so let's not unduly panic users. Signed-off-by: Carlos Corbacho <carlos@strangeworlds.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>
| | | * acer-wmi: Rename mail LED correctly & remove hardcoded colourCarlos Corbacho2008-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mail LED name for acer-wmi currently hardcodes in the colour as green. This is wrong, since many of the newer laptops now come with an orange LED, and we have no way of telling what colour is used on a given system. Also, rename the mail LED to be inline with the current recommendations of the LED class documentation.

Add an attribute to report this information, "hotkey_tablet_mode". This attribute has poll()/select() support, and can be used along with EV_SW SW_TABLET_MODE to hook userspace to tablet events.

Document these events, and avoid nasty messages when they happen. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

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.
