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.
