    Default Nouveau Advances NVIDIA NVF0/GK110 Support

    Phoronix: Nouveau Advances NVIDIA NVF0/GK110 Support

    The open-source reverse-engineered Nouveau driver now has 2D EXA acceleration and X-Video support for NVIDIA's "NVF0" or better known as the GK110 GPU found in the NVIDIA GeForce TITAN and GeForce GTX 780. Updates to the Nouveau DRM and Mesa Gallium3D driver have also arrived...

    Their wiki page doesn't have any "NVF0" nouveau code name.

    Thank you very much to the developers for this great effort on developing this driver!

    There's also RFC-level patches on the mesa-dev list today to add compute support for NVC0 (GeForce 400/500-series)... I'm sure there'll probably be a couple rounds of revisions, but progress is progress.

    This level of compute support is jus barely sufficient to read some registers and store the result in a buffer. That's it. Nothing to see here.

    However, reading some performance counters on NVIDIA cards is already possible on nve4 and support is being broaden thanks to Samuel's GSoC project. We are getting there!

    Nouveau for a 1300 USD graphics card?

    Who needs this project anyway? Same as AMD open source drivers?

    Both project will never be in good shape when needed most, compared to binary and EVERYONE and their dog know it.
    AMD made clear, they won't care for performance of OSS drivers.
    Nvidia doesn't even release documentation.

    Anyone who is paranoid enough would have Intel by now.
    Why even bother?

    Sounds like trolling, i know, but i want to know.

    AMD do care about performance of their open source drivers. What they said is that they would be happy if their open source drivers gave ~70% of the performance of the closed source drivers. It's not that they don't care, it's that their open source team has limited resources, and above that level of performance the performance increase that results from a fixed time investment decreases significantly.

    AMDs open source drivers have top-notch support for new kernels and X.org versions, whereas the binary driver does not - it often lags months behind. They also work out of the box, which simplifies things for the end user. The 2D performance is also better than their closed source driver (so I've heard - I don't use the closed driver).

    Now that UVD and power management code have been released, the open source drivers are set to be a very compelling alternative to the binary (though admittedly we need to wait for kernel 3.11 for power management). The open source driver also supports more hardware: binary supports HD 5000 series and newer, whereas the open source drivers support pretty much everything from the Radeon X800.

    Radeon with kernel 3.11 will be perfect for everything up to RadeonSI, they already match / get close to the performance of the closed source driver in a lot of cases, have UVD support, HDMI audio support, 3.11 brings Dynamic Power Management. The only thing missing is CrossFire. Radeon also supports the newest kernels and X-servers automatically, Catalyst lags behind by MONTHS supporting those.

    Intel is intel.. its the only game in town so thats it.

    Nouveau is screwed, sorry, but its true. I'm not sure how they are ever going to keep up with Nvidia or even get close enough to really make a big dent... combine that with the fact that Nvidia releases new drivers that support the newest kernels and X-servers sometimes before said kernels and X servers are even released, you can't even use that as a reason.


    Radeon matters and has a use.
    Intel definitely matters.
    Nouveau, I respect them for trying and DO wish them the best of luck, but I just don't see how they are gonna pull it off...

    Default If Nouveau didn't exist

    If Nouveau didn't exist, any distro using Gnome-shell, Unity, or Cinnamon would not open the desktop or open it in LLVMpipe on any computer with an Nividia card. I still remember Red Hat saying they could not make GNOME 3 the default on Fedora until Nouveau was able to open it on most machines that came with Nvidia cards.

    Nouveau is a hell of a lot faster than LLVMpipe. Not to rag on LLVMpipe either: if they didn't exist one mistake that fucks up your regular driver (say while you install that closed driver) and you would have to have a backup DE installed just to use X! If that happened with no wired internet access, on a new install, most users would get chicken and egg, needing X to connect to the network and the network to download a DE that would work and let them run X.

    Radeon, BTW, is good enough for my HD6750 to beat any graphics Intel makes. The only thing Nouveau needs to do the same is to figure out the reclocking issue, based on some tests comparing to AMD Evergreen set to the "mid" old-style power profile for similar clocks.Not only that, for what Intel costs I can have bulldozer and an HD6750, and get them from a manufacturer not as deeply embedded in the whole "Wintel" monopoly scheme.
