% Hot Keys, Video Control, Suspend/Resume, Oh
% My! -- Recent advances and current challenges in Linux/ACPI
%
% Len Brown (len.brown@intel.com)
*ACPI (Advanced Configuration and Power
Interface) is an open industry specification
establishing industry-standard interfaces for
OS-directed configuration and power management
on laptops, desktops, and servers.
ACPI enables new power management technology
to evolve independently in operating systems
and hardware while ensuring that they continue
to work together.
This paper begins with a brief overview
of ACPI features, a description of the
Linux/ACPI implementation, and the state of
Linux/ACPI deployment.
Detailed discussion of key technical areas
follows, highlighting recent progress in Linux
as well as current and future challenges. The
focus areas this year include plug-and-play
configuration; processor power management;
CPU, IO and memory hot-plug; laptop hot-keys;
video control and suspend/resume. In addition,
the ACPI 3.0 specification was published after
OLS last year, so we're now able to discuss
Linux's response to {ACPI 3.0} in some detail.
