*Ö÷Ì⣺ACPI in Linux - Myths vs Reality
*Ö÷½²ÈË£º Len Brown £¨Intel¹«Ë¾Äں˴óʦ£©
*ÄÚÈݼò½é£º
Major Linux distributors have been shipping ACPI in
Linux for several years, yet mis-perceptions about ACPI
persist in the Linux community. This talk addresses
the most common myths about ACPI in Linux.

*Ö÷Ì⣺Kernel-mode video driver for Linux
*Ö÷½²ÈË£º Jesse Barness £¨Intel¹«Ë¾Äں˴óʦ£©
*ÄÚÈݼò½é£º
This talk will focus on the Linux graphics space, providing an overview
of the current state of affairs, and the author's efforts to improve
them. We'll cover, in-depth, attempts to redesign the kernel's
graphics subsystem to improve user's suspend/resume, panic, and
graphics configuration experience. This will include an overview of
the current pieces of the graphics puzzle (e.g. kernel DRM, fb layer,
vgacon, X server, etc.), how they fit together (or not), and what can
be done to make them play together nicely (like centralizing important
functions in kernel space), with an eye toward the DRM modesetting
tree, which includes significant new kernel functionality and userspace
APIs to take advantage of it. Particular attention will be paid to
initial graphics discovery and configuration, modesetting, and memory
management
*Ö÷½²È˼ò½é£º
Jesse is a long time Linux and open source contributor. He is perhaps
best known for his role as Linux platform maintainer for SGI's Altix
line of Itanium based computers, in which he contributed significantly
to Linux scalability efforts, APIs for driver optimization, and new
userspace interfaces to allow user level drivers like X to be easily
ported to exotic platforms.
Jesse currently works at Intel's Open source Technology Center (OTC),
where he collaborates with other OTC developers on developing software
and drivers for Intel's graphics chips and platform architecture.
Current tasks include improve graphics on Linux, reducing power
consumption, and working on platform architecture for future Intel
Products
