    Phoronix: Kepler Clock Gating Queued In Nouveau DRM, Lowering Power Use

    Red Hat's Lyude Paul has been spending the past number of weeks working out clock-gating support for NVIDIA Kepler GPUs with the open-source Nouveau DRM kernel driver...

    kudos, hardware reverse engineering and driver development is a tough job, …

      Cool, I might finally be able to replace binary nvidia's driver with nouveau on 5 year old laptop.

        Why nvidia doesn't support open source drivers? For me, it's no go for nvidia.

          They want to keep full control of their hardware. If they are the ones making the driver they control where and when and how their hardware can be used. Like for example locking down features in driver while the hardware technically supports them.

            They could have just as easily given us nothing and left us with the same compromising situation we're in with WiFi hardware support, except in an even more critical hardware category. I think we should take what we can get.

              Wait, what? they basically have given us nothing, and left us with a binary blob wrapping windows driver just like ndiswrapper. If you want an open system, choose hardware that is natively supported by open source, and do not accept binary only windows blobs at the core.

                I didn't chose Linux to "take what I can get", sorry.

                They either opensource or I'm using their cards only on Windows.

                  Meaning, never. I don't use windows on my personal machines. I don't buy nvidia.

                    NVidia does have an open source driver, called nvgpu. I think it mostly targets Android. Though being typical NVidia, they ignore everyone else when working on it.
