Hi, just a question. If I had two systems, one with nouveau and the other with nvidia. And then I valgrind glxgears, for example. Would valgrind's output: 1- be the same in both systems? 2- be as much close as possible in both systems (the differences being due to implementations in the proprietary driver which are not implemented in nouveau) ? 3- or would it be entirely different in both systems? Thanks in advance for any help.. -------------- next part -------------- An HTML attachment was scrubbed...

Ideally valgrind output for both should be identical -- no leaks :) Are you asking about valgrind-mmt perhaps? The nouveau driver's GL implementation is going to be rather different from NVIDIA's in many many respects, both at the micro level (e.g. order of state being emitted and when that's done), to the entire approach to e.g. fbo flipping and lots of other things.

I'm sorry for my ignorance but I must ask. When you wrote: "The nouveau driver's GL implementation is going to be rather different from NVIDIA's in many..." Do you mean that valgrind-mmt will output differently in nouveau drivers'GL and NVIDIA's driver? Again, thanks for any help. 2015-04-24 10:34 GMT-04:00 Ilia Mirkin <imirkin at alum.mit.edu>:> Ideally valgrind output for both should be identical -- no leaks :) > > Are you asking about valgrind-mmt perhaps?
