Re: We want nvidia linux powerpc drivers !!
Reverse engineering is not an acceptable solution.
If NVIDIA want to keep the IP rights to their entire driver, they should then release well written hardware specifications documenting their older GPUs. From there, people will be able to write legal, IP compatible drivers for any architecture.
Writing documentation isn't cheap, I'll accept that, but neither is maintaining a driver.
Chinese Wall method is too complicated and would take too long, for a GPU.
