*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.
