2009-06-26eeepc-laptop: Register as a pci-hotplug deviceCorentin Chary
The eee contains a logically (but not physically) hotpluggable PCIe slot. Currently this is handled by adding or removing the PCI device in response to rfkill events, but if a user has forced pciehp to bind to it (with the force=1 argument) then both drivers will try to handle the event and hilarity (in the form of oopses) will ensue. This can be avoided by having eee-laptop register the slot as a hotplug slot. Only one of pciehp and eee-laptop will successfully register this, avoiding the problem.

2009-06-19eeepc-laptop: read rfkill soft-blocked state on resumeAlan Jenkins
This will respect state changes over hibernation, e.g. if the user disables the wireless in the BIOS setup screen. It reveals an issue where ACPI silently kills the wireless on suspend. Normally, the BIOS restores the correct state from non-volatile storage on boot. But when hibernation is aborted, the wireless would remain killed. Fortunately we can work around this in the resume handler by simply writing back the same value we read from NVS. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-06-19rfkill: don't restore software blocked state on persistent devicesAlan Jenkins
The setting of the "persistent" flag is also made more explicit using a new rfkill_init_sw_state() function, instead of special-casing rfkill_set_sw_state() when it is called before registration. Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification.

2009-06-18thinkpad-acpi: support the second fan on the X61Henrique de Moraes Holschuh
Support reading the tachometer of the auxiliary fan of a X60/X61. It was found out by sheer luck, that bit 0 of EC register 0x31 (formely HBRV) selects which fan is active for tachometer readings through EC 0x84/0x085: 0 for fan1, 1 for fan2. Many thanks to Christoph Kl??nter, to Whoopie, and to weasel, who helped confirm that behaviour. Fan control through EC HFSP applies to both fans equally, regardless of the state of bit 0 of EC 0x31. That matches the way the DSDT uses HFSP. In order to better support the secondary fan, export a second tachometer over hwmon, and add defensive measures to make sure we are reading the correct tachometer. Support for the second fan is whitelist-based, as I have not found anything obvious to look for in the DSDT to detect the presence of the second fan.

2009-06-18thinkpad-acpi: forbid the use of HBRV on Lenovo ThinkPadsHenrique de Moraes Holschuh
Forcing thinkpad-acpi to do EC-based brightness control (HBRV) on a X61 has very... interesting effects, instead of doing nothing (since it doesn't have EC-based backlight control), it causes "weirdness" in the fan tachometer readings, for example. This means the EC register that used to be HBRV has been reused by Lenovo for something else, but they didn't remove it from the DSDT. Make sure the documentation reflects this data, and forbid the user from forcing the driver to access HBRV on Lenovo ThinkPads.

This patch adds a .notify() method. The presence of .notify() causes Linux/ACPI to manage event handlers and notify handlers on our behalf, so we don't have to install and remove them ourselves. This driver relies on seeing system notify events, not device-specific ones (because it used ACPI_SYSTEM_NOTIFY).

2009-06-10rfkill: remove set_global_sw_stateAlan Jenkins
rfkill_set_global_sw_state() (previously rfkill_set_default()) will no longer be exported by the rewritten rfkill core. Instead, platform drivers which can provide persistent soft-rfkill state across power-down/reboot should indicate their initial state by calling rfkill_set_sw_state() before registration. Otherwise, they will be initialized to a default value during registration by a set_block call. We remove existing calls to rfkill_set_sw_state() which happen before registration, since these had no effect in the old model. If these drivers do have persistent state, the calls can be put back (subject to testing :-). This affects hp-wmi and acer-wmi. Drivers with persistent state will affect the global state only if rfkill-input is enabled. This is required, otherwise booting with wireless soft-blocked and pressing the wireless-toggle key once would have no apparent effect. This special case will be removed in future along with rfkill-input, in favour of a more flexible userspace daemon (see Documentation/feature-removal-schedule.txt). Now rfkill_global_states[n].def is only used to preserve global states over EPO, it is renamed to ".sav".

Preset 1 is the default setting with default clocks and voltage. The new eeepc-laptop driver doesn't support it anymore. The attached patch adds support for it to eeepc-laptop.

2009-05-14eeepc-laptop: Work around rfkill firmware bugAlan Jenkins
1) Buggy firmware can change the RFKILL state by itself. This is easily detected. The RFKILL API states that in such cases, we should call rfkill_force_state() to notify the core. I have reported the bug to Asus. I believe this is the right thing to do for robustness, even if this particular firmware bug is fixed. 2) The same bug causes the wireless toggle key to be reported as 0x11 instead of 0x10. 0x11 is otherwise unused, so it should be safe to add this as a new keycode. The bug is triggered by removing the laptop battery while hibernated. On resume, the wireless toggle key causes the firmware to toggle the wireless state itself. (Also, the key is reported as 0x11 when the current wireless state is OFF). This is very poor behaviour because the OS can't predict whether the firmware is controlling the RFKILL state. Without this workaround, the bug means users have to press the wireless toggle key twice to enable, due to the OS/firmware conflict. (Assuming rfkill-input or equivalent is being used). The workaround avoids this. I believe that acpid scripts which toggle the value of the sysfs state file when the toggle key is pressed will be rendered ineffective by the bug, regardless of this workaround. If they simply toggle the state, when the firmware has already toggled it, then you will never see a state change. Tested on "EEEPC 4G" only.

2009-05-14eeepc-laptop: report brightness control events via the input layerDarren Salt
This maps the brightness control events to one of two keys, either KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed. Some mapping has to be done due to the fact that the BIOS reports them as <base value> + <current brightness index>; the selection is done according to the sign of the change in brightness (if this is 0, no keypress is reported).

2009-05-14eeepc-laptop: fix wlan rfkill state change during initAlan Jenkins
When an rfkill device is registered, the rfkill core will change its state to the system default. So we need to prepare for state changes *before* we register it. That means installing the eeepc-specific ACPI callback which handles the hotplug of the wireless network adaptor. This problem doesn't occur during normal operation. You have to 1) Boot with wireless enabled. eeepc-laptop should load automatically. 2) modprobe -r eeepc-laptop 3) modprobe eeepc-laptop On boot, the default rfkill state will be set to enabled. With the current core code, step 2) will disable the wireless. Therefore in step 3), the wireless will change state during registration, from disabled to enabled. But without this fix, the PCI device for the wireless adaptor will not appear.
