    Thanks, Yoshi. I followed the link. I still don't fully dig it. If this is residing in the kernel, how is it different from other drivers/components? To be specific, if someone want to access the new KMS or TTM in user space, can they just do it? If so, how is this different from being a proper driver/kernel component?

    Many thanks!
    Think you will need to enable the development/experimental driver config option when configuring the kernel.

      yes, this is pretty much successor to the experimental drivers, that were available in the kernels some releases ago. experimental however, didn't really work out - quite a lot of features were left in experimental for too long and its meaning diminished over time.

      user accepting to use staging drivers must be prepared for missing features, crashes and random operation.

      staging is sort of a testbed for new drivers, and new technologies inside the kernel. it can also contain the code that does not yet meet kernel quality standards (e.g. in case of drm/ttm pull there are reports of possible security holes in the current code).

      if somebody wants to take them for a spin, they just need to change few variables in kernel config and rebuild it. this removes the need to throw multiple patches from different sources against the kernel just take some new drivers for a spin.
