Linux "Now that the kernel mode-setting page-flipping for the ATI Radeon DRM kernel module has been merged into the Linux 2.6.38 kernel and the respective bits have been set in the xf86-video-ati DDX, we're in the process of running new open-source ATI graphics benchmarks under Linux. Our initial results (included in this article) show these latest improvements to cause some major performance boosts for the open-source ATI driver as it nears the level of performance of the proprietary Catalyst driver."

"Modsetting in the kernel is KMS.

No, KMS is one possible implementation of doing modesetting in the kernel. Nvidia uses another, their own. Wayland doesn't care how the mode is set, just that it is set.
Exactly. KMS is used to name 2 separate things here: it literally stands for Kernel Mode Setting, but it also is the name of the implementation the OSS drivers use.

There can be many different implementations of KMS - the OSS drivers use one called "KMS" while the proprietary drivers implement their own versions in their kernel modules.

Wayland requires an implementation of KMS, but it won't specifically require the same one that the OSS drivers are currently using.
