* rfkill: add default global states (v2)Henrique de Moraes Holschuh2008-08-222-12/+116
| | | | | | | | | | | | | | | | | | | Add a second set of global states, "rfkill_default_states", to track the state that will be used when the first rfkill class of a given type is registered, and also to save "undo" information when rfkill_epo is called. Add a new exported function, rfkill_set_default(), which can be used by platform drivers to restore radio state saved by the platform across reboots or shutdown. Also, fix rfkill_epo to properly update rfkill_states, but still preserve a copy of the state so that we can undo the effect of rfkill_epo later if we want to. Add rfkill_restore_states() to restore rfkill_states from the copy. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rfkill: query EV_SW states when rfkill-input (re)?connects to a input deviceHenrique de Moraes Holschuh2008-08-011-15/+39
| | | | | | | | | | | | | | | | Every time a new input device that is capable of one of the rfkill EV_SW events (currently only SW_RFKILL_ALL) is connected to rfkill-input, we must check the states of the input EV_SW switches and take action. Otherwise, we will ignore the initial switch state. We also need to re-check the states of the EV_SW switches after a device that was under an exclusive grab is released back to us, since we got no input events from that device while it was grabbed.

| | | | | | | | | | | | | | | | | There are two mutexes in rfkill: rfkill->mutex, which protects some of the fields of a rfkill struct, and is also used for callback serialization. rfkill_mutex, which protects the global state, the list of registered rfkill structs and rfkill->claim. Make sure to use the correct mutex, and to not miss locking rfkill->mutex even when we already took rfkill_mutex.

* rfkill: fix led-trigger unregister order in error unwindHenrique de Moraes Holschuh2008-07-291-2/+4
| | | | | | | | | | | | | | | | | | rfkill needs to unregister the led trigger AFTER a call to rfkill_remove_switch(), otherwise it will not update the LED state, possibly leaving it ON when it should be OFF. To make led-trigger unregistering safer, guard against unregistering a trigger twice, and also against issuing trigger events to a led trigger that was unregistered. This makes the error unwind paths more resilient. Refer to "rfkill: Register LED triggers before registering switch".

* rfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switchHenrique de Moraes Holschuh2008-07-081-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | rfkill_add_switch() calls rfkill_toggle_radio() to set the state of a recently registered rfkill class to the current global state [for that rfkill->type]. The rfkill_toggle_radio() call is going to error out if the hardware is RFKILL_STATE_HARD_BLOCKED, and the global state is RFKILL_STATE_UNBLOCKED. That is a quite normal situation which I missed to account for. As things stand, the error return from rfkill_toggle_radio ends up causing rfkill_register to bail out with an error (de-registering the new switch in the process), which is Not Nice. Change rfkill_add_switch() to not return errors because of a failed call to rfkill_toggle_radio(). We can go back to returning errors again (if that's indeed the right thing to do) if we define the exact error codes the rfkill->toggle_radio callbacks are to return in each situation, so that we can ignore the right ones only.

* rfkill: rename the rfkill_state states and add block-locked stateHenrique de Moraes Holschuh2008-06-262-28/+76
| | | | | | | | | | | | | | | | | | | | | | | | | The current naming of rfkill_state causes a lot of confusion: not only the "kill" in rfkill suggests negative logic, but also the fact that rfkill cannot turn anything on (it can just force something off or stop forcing something off) is often forgotten. Rename RFKILL_STATE_OFF to RFKILL_STATE_SOFT_BLOCKED (transmitter is blocked and will not operate; state can be changed by a toggle_radio request), and RFKILL_STATE_ON to RFKILL_STATE_UNBLOCKED (transmitter is not blocked, and may operate). Also, add a new third state, RFKILL_STATE_HARD_BLOCKED (transmitter is blocked and will not operate; state cannot be changed through a toggle_radio request), which is used by drivers to indicate a wireless transmiter was blocked by a hardware rfkill line that accepts no overrides. Keep the old names as #defines, but document them as deprecated. This way, drivers can be converted to the new names *and* verified to actually use rfkill correctly one by one.

| | | | | | | | | | | | | | | | SW_RFKILL_ALL is the "emergency power-off all radios" input event. It must be handled, and must always do the same thing as far as the rfkill system is concerned: all transmitters are to go *immediately* offline. For safety, do NOT allow userspace to override EV_SW SW_RFKILL_ALL OFF. As long as rfkill-input is loaded, that event will *always* be processed, and it will *always* force all rfkill switches to disable all wireless transmitters, regardless of user_claim attribute or anything else.

Userspace should use these events for OSD/status report applications and rfkill GUI frontends. HAL might want to broadcast them over DBUS, for example. It might be also useful for userspace implementations of rfkill-input, or to use HAL as the platform driver which promotes rfkill switch change events into input events (to synchronize all other switches) when necessary for platforms that lack a convenient platform-specific kernel module to do it.

* rfkill: add read-write rfkill switch supportHenrique de Moraes Holschuh2008-06-261-3/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, rfkill support for read/write rfkill switches is hacked through a round-trip over the input layer and rfkill-input to let a driver sync rfkill->state to hardware changes. This is buggy and sub-optimal. It causes real problems. It is best to think of the rfkill class as supporting only write-only switches at the moment. In order to implement the read/write functionality properly: Add a get_state() hook that is called by the class every time it needs to fetch the current state of the switch. Add a call to this hook every time the *current* state of the radio plays a role in a decision. Also add a force_state() method that can be used to forcefully syncronize the class' idea of the current state of the switch. This allows for a faster implementation of the read/write functionality, as a driver which get events on switch changes can avoid the need for a get_state() hook. If the get_state() hook is left as NULL, current behaviour is maintained, so this change is fully backwards compatible with the current rfkill drivers. For hardware that issues events when the rfkill state changes, leave get_state() NULL in the rfkill struct, set the initial state properly before registering with the rfkill class, and use the force_state() method in the driver to keep the rfkill interface up-to-date. get_state() can be called by the class from atomic context. It must not sleep. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: John W.

* rfkill: add parameter to disable radios by defaultHenrique de Moraes Holschuh2008-06-261-1/+10
| | | | | | | | | | | | | | | | | Currently, radios are always enabled when their rfkill interface is registered. This is not optimal, the safest state for a radio is to be offline unless the user turns it on. Add a module parameter that causes all radios to be disabled when their rfkill interface is registered. The module default is not changed so unless the parameter is used, radios will still be forced to their enabled state when they are registered. The new rfkill module parameter is called "default_state". Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.
