hmm...sorry, what is the advantage of using your own module over using unix local sockets (or even FIFOs). If both ends of the communication are in userspace, I wonder if a custom kernel module will be faster than unix sockets?

EDIT: current issue: GL_INVALID_OPERATION, this error comes from the blob drivers when the chroot calls glCopyTexImage2D, what is weird though, i added printfs in the decoder methods and it seems glCopyTexImage2D is never called on the host
