* | misc: add HP WMI laptop extras driverMatthew Garrett2008-07-253-0/+507
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver adds support for reading and configuring certain information on modern HP laptops with WMI BIOS interfaces. It supports enabling and disabling the ambient light sensor, querying attached displays and hard drive temperature, sending events on docking and querying the state of the dock and toggling the state of the wifi, bluetooth and wwan hardware via rfkill. It also makes the little "(i)" button work on machines that send that via WMI rather than via the keyboard controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a read/write rfkill interface to the bluetooth radio switch on the bluetooth submodule, and one for the wireless wan radio switch to the wan submodule. Since rfkill does care for when a switch changes state, use WLSW notifications to also check if the WWAN or Bluetooth switches did not change state (due to them being slaves of WLSW in firmware/hardware, but that reality not being always properly exported by the thinkpad firmware).

| * | ACPI: thinkpad-acpi: WLSW overrides other rfkill switchesHenrique de Moraes Holschuh2008-07-211-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ThinkPads where the WLSW switch exists, the firmware or the hardware ANDs the WLSW state with the device-specific switches (WWAN, Bluetooth). It is downright impossible to enable WWAN or Bluetooth when WLSW is blocking the radios. This reality does not necessarily carry over to the WWAN and Bluetooth firmware interfaces, though... so the state thinkpad-acpi was reporting could be incorrect. Tie the three switches in the driver so that we keep their state sane. When WLSL is off, force the other switches to off as well. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>

| | | | | | | | | | | | | | | | | | | | | Add a debugfs file for showing the full results of the method we use to detect devices on WMID laptops. This should be useful in the case that a Linux user gets an Acer laptop with 3G support (and/ or people who enjoy ripping their wireless cards out) so we can get some feedback on how this value changes in these cases. (At the moment, we always enable the wireless and 3G control. In the case of the former, this is fairly safe. In the case of the latter though, trying to toggle this device if it doesn't exist on a laptop causes ACPI warnings/ errors). To summarise: If you have an Acer laptop with a built in 3G card, please report back the value from this file.

This can be disabled using a module parameter if it causes issues with models which handle these keys transparently in the BIOS. * Actions of additional hotkeys found on some Fujitsu models (eg: the suspend key and the dedicated "power on passphrase" keys) are broadcast to userspace. * An alternative brightness control method used by some Fujitsu models (for example, the S6410) is now supported, enabling software brightness controls on models using this method. * DMI-based module aliases are configured for the S6410 and S7020. * The current LCD brightness after booting should now be reflected in the standard backlight interface sysfs file (previously it was always set to 0). The platform brightness sysfs interface has always been fine. Thanks go to Peter Gruber who provided a significant portion of this code and tested various iterations of the patch on his S6410.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The less tested codepaths for LED handling, used on ThinkPads 570, 600e/x, 770e, 770x, A21e, A2xm/p, T20-22, X20 and maybe a few others, would write data to kernel memory it had no business touching, for leds number 3 and above. If one is lucky, that illegal write would cause an OOPS, but chances are it would silently corrupt a byte. The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add sysfs led class support to thinkpad leds (v3.2)". Fix the bug by refactoring the entire code to be far more obvious on what it wants to do. Also do some defensive "constification". Issue reported by Karol Lewandowski <lmctlx@gmail.com> (he's an lucky guy and got an OOPS instead of silent corruption :-) ). Root cause of the OOPS identified by Adrian Bunk <bunk@kernel.org>.

| * | kgdbts: Use HW breakpoints with CONFIG_DEBUG_RODATAJason Wessel2008-05-281-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever CONFIG_DEBUG_RODATA is set in the kernel config many kernel text sections become read-only, and the use of software breakpoints in the kgdb tests will cause the kernel to fail to complete the start up. Until such time that there is an official API for modifying read-only text sections hardware breakpoints must be used to run the do_fork or sys_open tests or the tests get skipped.

| | | | | | | | | | | | Make XP return values more generic to XP and not so tied to XPC by changing enum xpc_retval to xp_retval, along with changing return value prefixes from xpc to xp. Also, cleanup a comment block that referenced some of these return values as well as the handling of BTE related return values.

* kgdb: 1000 loops for the single step test in kgdbtsJason Wessel2008-05-051-2/+13
| | | | | | | | | | | | | The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.
