No, at least the 3D parts obviously have to be different, and IIRC Adam Kirchhoff tried the R200 microcode without success even for just 2D. > > > I might have some success in figuring out CP sequences and present the > > > result as a user-space library, but I doubt I will have time to dig > > > inside Mesa. > > > > We have the docs, no need to guess... note that unprivileged user space > > processes can't emit CP commands directly but can only use higher level > > ioctls geared towards the 3D driver.
