A Preview Of Kernel-Based Mode-Setting

[ Thanks to Michael Larabel for this

“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…”
