2009-04-22ACPI: delete obsolete "bus master activity" proc fieldLen Brown1-1/+0
Linux-2.6.29 deleted the legacy ACPI idle handler, leaving the CPU_IDLE handler, which does not track bus master activity. So delete the unused bm_activity field -- it is confusing to print an always zero value. This patch could break programs that parse /proc/acpi/processor/*/power, since it deletes this line from that file: bus master activity: 00000000 http://bugzilla.kernel.org/show_bug.cgi?id=13145 is not fixed by this patch, but provoked this patch.

2009-04-07hwmon: Add Asus ATK0110 supportLuca Tettamanti1-2/+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.

2009-04-05ACPI: support acpi_device_ops .notify methodsBjorn Helgaas2-0/+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>

to prevent wrongly overwriting fixmap that still want to use. ACPI used to rely on low mappings being all linearly mapped and grew a habit: it never really unmapped certain kinds of tables after use.

2009-02-07ACPI: Enable bit 11 in _PDC to advertise hw coordPallipadi, Venkatesh1-0/+2
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.
