Nouveau for RandR 1.2 is getting better one step at a time while debugging has become a bit more difficult due to changes in the API for DRM. Also happening for the Nouveau project are two new scripts that were entered into the SourceForge CVS: crashdump and createdump. Crashdump collects all helpful information about a X11 crash (similar to the ATI and NVIDIA bug collection tools). Createdump on the other hand automates the process of running renouveau carrying everything out from downloading it to running the tests and then archiving the results of the renouveau tests.
Reverse engineering of the G84 GPU is also underway but it's expected to take a while; 2D for G80 cards should be working though. The Nouveau project also ran into another man that was working on reverse engineering the G70 and G80 series graphics cards and didn't know about the Nouveau driver, but now they may join forces. Help is still needed for more MMIO dumps on cards not properly handling glxgears along with the testing of the crashdump and createdump scripts. Discuss NVIDIA Linux in the Phoronix Forums.
