Title: A Preview Of Kernel-Based Mode-Setting ( -at -) Phoronix

Summary: "There are many new and innovative features brewing within the

X.Org development community right now -- among the many are Gallium3D,

the TTM memory manager, and MPX (Multi-Pointer X) -- but one of the

features that has risen towards the top of the list and delivers visible

benefits to the end-user is kernel-based mode-setting. As implied by its

name, kernel mode-setting involves moving the mode-setting code for

video adapters from the user-space X server drivers into the Linux

kernel. This may seem like an uninteresting topic for end-users, but

having the mode-setting done in the kernel allows for a cleaner and

richer boot process, improved suspend and resume support, and more

reliable VT switching (along with other advantages). Kernel mode-setting

isn't yet in the mainline Linux kernel nor is the API for it frozen, but

Fedora 9 shipping next month will be the first major distribution

carrying this initial support. In this article we're looking more

closely at kernel mode-setting with the Intel X.Org driver as well as

showing videos of kernel-based mode-setting in action."
