Hi List! Recently on the [SLE] (SuSE Linux English Mailing list) there were discussions over Xgl, and I was bashing ATI and specially nvidia (I have a TNT2, sorry).
But, this got my attention, and I don't know nothing about this subject: ------------->>> Quote "The DRI/UtahGLX support for nVidia is pretty much NV0x only (maybe NV10/15 limitedly) and _lacks_ features for compiz last time I checked. Those developments were based on -- and I wish more people knew this -- nVidia's *100% SOURCE CODE RELEASE WITH OPENGL/GLX ACCELERATION!* Yes, nVidia released 100% of the source code in the XFree86 3.3.x days, changing identifiers and other things to protect IP. Unfortunately, it didn't stop the lawyers from Intel, Microsoft and others from sending cease'n desist letters. That's when nVidia decided to move the 3D code to an unified model across all OSes, with a dynamic loader. Intel's IP is at the heart of ATI and nVidia's kernel driver. IP Intel itself won't release for its own Linux drivers, but key to the unified model. Long story." /Quote ------------->>> This is me :) On Tue, 2006-05-23 at 10:08 -0300, Alvaro Kuolas wrote: > > What's wrong with you people! > > Were is your GNU GPL spirit? > And this is the Quote: "It's called intellectual property (IP). IP is _always_ going to be an issue with GPUs (Graphical Processing Unit), _period_. Today's GPUs are _more_powerful_ than CPUs. It's like having a CPU with specialized vector units. And must is driven in specialized software. A lot of that IP is either Intel's or, increasingly via cross-licensing agreements, Microsoft. An additional problem at the _hardware_ level is the Intel platform design itself. The reason why ATI and nVidia need kernel drivers is largely Intel's fault. Intel continues to have _no_ "system" interconnect and connects the GPU via an "peripheral" interconnect. So it has to use hacks in software for coherency between the GPU and CPUs. If we all used AMD HyperTransport eXtension (HTX) for GPUs like we do Infiniband and select other expansions, then we wouldn't have a problem. But as of right now, except for a few non-commodity, multi-GPU, specialized systems, HTX isn't available for GPUs. And that's not likely to change with Intel's control over the GPU industry -- especially when it comes to IP." /Quote ------------->>> Sorry to bring this subject on the mailing list, but This is true? I though that Intel is the most open with its GPUs. ATI is with it's "hands tide" because they bought FireGL (and a lot of "IP" that can't be "disclosed"), I don't know for nvidia. thanks() -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
