    Phoronix: The X.Org Foundation Is Funding Work To Improve Nouveau Re-Clocking

    The X.Org Foundation has decided to fund an Endless Vacation of Code project to improve the support for the Nouveau driver's re-clocking of several generations of NVIDIA GPUs...

    I'm very impressed with the AMD open source drivers, but I would also love to see Nouveau become equally as good.

      What job does Roy Spliet have that he can take 12 weeks off to work on this? Either he's self-employed or has a very understanding employer.

          PhD-seeking to be precise. X.org EVoC for me is a great opportunity to bridge this gap and focus my attention solely on nouveau.

            It'd be nice if noveau was equally as good as the radeon or intel drivers, but honestly I don't really care, because the closed source drivers are more than good enough if you care about gaming. For me, as long as the hardware performs the way it should (or close enough) and if I don't have to pay extra to make them work then I'm satisfied. With AMD the situation is a little different - their catalyst drivers aren't that great, so its nice having an alternative that is quickly improving. It feels like the radeon driver progression has been slowing down a bit but I have a good feeling that they're working on something big. They've got a good team.

              The radeon drivers are great (foss that is,) I have really benefited from their improvement over the last 4 years; i only hope that attempts like this can make take the nouveau project ahead. The nouveau team has been doing great things lately, and we all know the reclocking is the big ticket item holding back adoption.

              The vendor drivers may be good enough for you but I hate all the extra effort it takes to use them, and the periodic breakage that comes from them. Try using an alt. Kernel and it only get's worse. Another pending issue is xwayland support.

              I am excited by this work, even though my current card is one that is reported to already work with the existing reclocking effort.

                It depends on what you do. If you go out of your way to install the latest drivers on a distro like ubuntu, you're going to have a bad time. Stick with what your distro recommends and there's no effort involved, especially with nvidia. I've heard countless complaints about setting up catalyst and I really wonder what people are doing wrong to have such a hard time. I don't use catalyst anymore though, for reasons such as disk space, KDE "fluidity", future wayland support, and the fact that (so far) the Heaven benchmark is the only thing I have that takes advantage of crossfire.

                  While I think contributions to opensource software all in all is a good thing, aren't this kind of sponsored projects sending the signal to Intel and AMD that companies are rewarded for their opensource-hostile strategies rather than condemned?

                    It's a better idea to not put people with NVIDIA graphic cards “on the side of the road”. Supporting a proprietary format is fine, see LibreOffice or GIMP supporting .doc or .psd more or less well. It's much better than using the proprietary software.

                    Both AMD and Intel are actually hostile to free/libre software, outside of the graphics area.

                      Yeah but eg re-clocking is afaik something that AMD invested a lot of time and money to get for opensource drivers. Some manager *might* interpret that as no point investing because X.org Foundation will invest in competitors to get similar functionality anyway.

                        This should bring Nouveau to parity with r600

                        I think it was last summer that I tested the Radeon HD6750 and the GTS450 back to back on open drivers, and got performance roughly in proportion to clock speed in Scorched3d and in Critter. Scorched3d performance had risen from maybe 11-15 fps to about 33, and I was only getting 50-60 with the AMD card on max clocks. This was with no reclocking on the Nvidia card, something that had patially worked in 2011 but with a minimal effect on performance due to the lack of memory reclocking.

                        That GTS450, BTW is a good card for Nouveau as it stands. It's boot clocks are around 450 MHZ, making an used one bought cheap the equivalent of a smaller card running at higher clocks in both power use and performance. Mine never got over 40C in Nouveau, even with a resistor slowing down the fan to keep it quiet. The larger cards reportedly have far worse performance issues, due to lower boot clocks. I've never owned one of the larger cards, however.

                        Honestly no game I was using last Summer would I see any difference between it and my good radeon if I did not call the fps display. Scorched3 now has some bigger maps that can bog down the Radeon, however, so this has presumably changed. Also, for some reason that Nvidia card, on Nouveau and only on Nouveau outperformed every other card/driver combo I tried on Kdenlive video editing timeline playback. It handled transitions with almost no lag, even the heaviest of them.

                        Don't write off Nouveau: if this reclocking work is sucessful we will have 4 times as many good Linux graphics cards in existing circulation, as Nvidia is reported to sell about 3x as many cards as AMD. We will have four first rate drivers: Intel, Nouveau, R600, and RadeonSI, covering almost all x86 compatable hardware made since 2008.

                          I have two 9600GTs, I'd be willing to donate one (or both if that's somehow useful). Just give me an address and some way to feel it's legitimate.

                            Intel contributes to quite a few open-source projects, and that includes being one of the top contributors to the Linux kernel. I'm not sure what kind of mental gymnastics you're doing to classify them as hostile to open-source.

                              His comment was so stupid I ended up passively ignoring it... Just a couple AMD contributions if their own word isn't good enough:
