| * ACPI: dock: add access to ACPI docking station UIDIlya A. Volynets-Evenbakh2007-03-09
| | | | | | | | | | | | | | | | | | | | It is useful to know whether your laptop is docked or not, but it is even more useful to know which docking station it's docked to. Attached patch adds "uid" file to sysfs. Tested on Dell Latitude D600 with D/Dock. Patch is against official 2.6.20 release. Signed-off-by: Len Brown <len.brown@intel.com>

| * | | ACPI: prevent ACPI quirk warning mass spamming in logsThierry Vignaud2007-04-25

The ATI quirk below probably needs a similar "fix" but I don't have the hardware to test. Btw arch/x86_64/kernel/early-quirks.c::nvidia_bugs() would probably need to be synced (but I don't have an x86_64 NVidia motherboard to boot test it).

| * | | ACPI: make /proc/acpi/wakeup more usefulDavid Brownell2007-04-25

Example: Device S-state Status Sysfs node PCI0 S4 disabled no-bus:pci0000:00 PS2M S4 disabled pnp:00:05 PS2K S4 disabled pnp:00:06 UAR1 S4 disabled pnp:00:08 USB1 S3 disabled pci:0000:00:03.0 USB2 S3 disabled pci:0000:00:03.1 USB3 S3 disabled USB4 S3 disabled pci:0000:00:03.3 S139 S4 disabled LAN S4 disabled pci:0000:00:04.0 MDM S4 disabled AUD S4 disabled pci:0000:00:02.7 SLPB S4 *enabled Eventually this file should be removed, but until then it's almost the only way we have to tell how the relevant ACPI tables are broken (and cope). In that example, two devices don't actually exist (USB3, S139), one can't issue wakeup events (PCI0), and two seem harmlessly (?) confused (MDM and AUD are the same PCI device, but it's the _modem_ that does wake-on-ring). In particular, we need to be sure driver model nodes are properly hooked up before we can get rid of this ACPI-only interface for wakeup events.

There is a good chance he is quite correct on this, especially if someone decides to use that interface in applets and users are not aware of its risks. This patch adds a master switch to thinkpad-acpi that enables or disables the entire fan-control feature as a module parameter: "fan_control". It defaults to disabled. Set it to non-zero to enable fan control. Also, the patch removes the expermiental status from fan control, since it is stable enough to not be called experimental, and the master switch makes it safe enough to do so.

If the EC ignores the AUTO or FULL-SPEED bits, it will pay attention to the lower three bits that set the fan level. And as thinkpad-acpi was leaving these set to zero, it would stop(!) the fan, which is Not A Good Thing. So, as a safety net, we now make sure to also set the fan level part of the HFSP register to speed 7 for full-speed, and a minimum of speed 4 for auto mode.

Also, fix some stray "thermal" files in the fan procfs description that have been there forever, and officially support "full-speed" as the name for the PWM-disabled state of the fan controller to keep it in line with the hwmon interface. It is much better a name for that mode than the unobvious "disengaged" anyway. Change the procfs interface to also accept full-speed as a fan level, but still report it as disengaged for backwards compatibility.

Sensors that are not available return -ENXIO when accessed. Up to 16 thermal sensors are supported on new firmware (but nobody has reported a ThinkPad with more than 12 sensors so far), and 8 sensors are supported on older firmware. Thermal sensor mapping is model-specific. Precision varies, it is 1 degree Celcius on new ThinkPads, but higher on some older models.
