* | hwmon: Add Asus ATK0110 supportLuca Tettamanti2009-04-071-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | Asus boards have an ACPI interface for interacting with the hwmon (fan, temperatures, voltages) subsystem; this driver exposes the relevant information via the standard sysfs interface. There are two different ACPI interfaces: - an old one (based on RVLT/RFAN/RTMP) - a new one (GGRP/GITM) Both may be present but there a few cases (my board, sigh) where the new interface is just an empty stub; the driver defaults to the old one when both are present. The old interface has received a considerable testing, but I'm still awaiting confirmation from my tester that the new one is working as expected (hence the debug code is still enabled). Currently all the attributes are read-only, though a (partial) control should be possible with a bit more work.

* ACPI: support acpi_device_ops .notify methodsBjorn Helgaas2009-04-052-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for ACPI device driver .notify() methods. If such a method is present, Linux/ACPI installs a handler for device notifications (but not for system notifications such as Bus Check, Device Check, etc). When a device notification occurs, Linux/ACPI passes it on to the driver's .notify() method. In most cases, this removes the need for drivers to install their own handlers for device-specific notifications. For fixed hardware devices like some power and sleep buttons, there's no notification value because there's no control method to execute a Notify opcode. When a fixed hardware device generates an event, we handle it the same as a regular device notification, except we send a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff range used by Notify opcodes. Several drivers install their own handlers for system Bus Check and Device Check notifications so they can support hot-plug. This patch doesn't affect that usage. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Reviewed-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | Bit 11 in intel PDC definitions is meant for OS capability to handle hardware coordination of P-states. In Linux we have always supported hwardware coordination of P-states. Just let the BIOSes know that we support it, by setting this bit. Some BIOSes use this bit to choose between hardware or software coordination and without this change below, BIOSes switch to software coordination, which is not very optimal in terms of power consumption and extra wakeups from idle.
