    Phoronix: Part 2 Of Nouveau Saga: The Microcode

    Following a feature-packed DRM pull request this morning for the Linux 2.6.33 kernel, Linus Torvalds became frustrated that the Nouveau driver for supporting NVIDIA hardware was still not to be found in this most recent pull request. Linus wants Nouveau in the mainline kernel especially as Red Hat has already been shipping this free software driver in Fedora for two releases. Only a few hours have passed since that second news article, but more messages surrounding the Nouveau status have been sent on the kernel mailing list and dri-devel...

    I thought the whole point of reverse engineering this ting from the ground up was so that we wouldn't have to deal with issues like this...

      Will nvidia respond? How might they respond? Will power users move away from ubuntu in 2010 because its lagging in this department? Or perhaps using nouveau will not be desirable until ubuntu 10.10? Perhaps at ubuntu 10.10 the kernel / X / driver situation will be perfected and we will all use nouveau and have blazing fast tear free rendering, flicker free booting incredible gaming performance as we flip between quake wars 2 and google chrome on our multicore 64 bit beast machines. Perhaps with virtualbox direct3d support thru gallium we can have a 4x4 cube wall of virtualized windows guests on our 16 core, 32gig ram monsterbox running every quake version and call of duty version ever made and 1080p video decoding on the other side, all balanced perfectly with the CFS scheduler, or perhaps kernel patching will return and we all will use the BFS and jenx adxobe will finally balance the CFQ so well that all those games can load levels at the same time from our SSD drive arrays as we are backing up our complete FLAC discography of all recorded works ever made to our vulcan database exabyte western digital NAS android cell phones. Only time will tell.

        Linus should get off his high horse

        the project is open source. Linus should stop being a brat and get off his high horse and do the work himself if he is so concerned about it. He shouldn't be yelling at the community, especially since most of them aren't paid.

        He should probably be worried about the shitty state of the entire graphics stack on linux more than one piece of DRM code. Xorg and mesa are in a poor state and are continuously falling short of goals.

          I don't think you will see that with nouveau. But with ati's oss implementation you might.

            Would it be likely that nVidia have patents or licensed code in the microcode?

              That could very well be the case...as there might even be 3rd party code contained in the microcode. That would have to be determined by nVidia though. If they cannot license the microcode, then most likely it is due to 3rd party licenses.

                Two things:

                1) Linus only deals with the kernel level parts of the stack, which is exactly what he is complaining about

                2) Most of the people he yells at are paid to work on it.

                  Repeat after me:

                  "I will not link to SourceForge mailing list archives."

                  They are crap to navigate. In fact, I have no idea how I can easily go to previous/next message in the thread there.

                      Personally, I'm glad that finally someone steps up and asks the nouveau guys to get their act together.
                      As brilliant as they are at hacking away sophisticated code and understanding complex hardware, they suck at "public relations".

                        They had an act? I thought they just floated around banging out code for with no real notice of improvements to anyone... :P

                          Reverse engineering does not protect you as far as possible patent restrictions. If nvidia for example has a patent on a process and that the reversed engineered firmware duplicates obtained in a clean room environment, from scratch or copying knowingly or not, it may very well infringe on patents made by nvidia or partners they license from. A simplified example:

                          Two guys are inventors, they both are developing mouse traps. Guy A has a piece of wood, a spring, and some stiff wire and comes up with the spring trap and patents it. Guy B with the same materials without even knowing it has already been patented comes up with a design looking very similar in looks and functionality and uses the same principals. Guy B is in patent infringement if he tries to market it (price really isn't a issue here, could be a freebie or charging for it).

                          Bottom line is patent infringement, no matter if it is ignorant of the patent or not, is still illegal in the eyes of patent law.

                            I think this is the closest you can get

                              Nouveau doesn't owe anybody anything. All but one of the regular contributors are working on it IN THEIR SPARE TIME, and the one who isn't is busy writing a lot of code. Everybody who uses it and updates it on a regular basis definitely sees the progress, even on the Gallium side. Anyone who wants to use it is free to do so, it's fairly easy to install. That just leaves the people in the peanut gallery who apparently don't use it and who complain that they don't know what's going on and somehow think that "public relations" is a worthwhile thing for VOLUNTEERS to spend their already limited time on. Some of these people even write articles without even asking the Nouveau folks what they've been up to! Last I heard "public relations" wasn't a synonym for "writing code" or "reverse-engineering" or any of the other things that are far higher on the priority scale for a small project of mostly volunteers.
