same system "image" at the same time.
In fact, I'm trying to support multiprocessing in an experimental architecture
of Microblazes on an FPGA. There isn't (HW) cache coherency and RAM is
accessed through per processor dedicated buses, thus shared access locking
must be realized either in a software manner or through a dedicated hardware mutex.

work? What specifically do you find lacking?
greg k-h
No doubt that the ultimate documentation is the code but still allow me
to consider that a higher level overview, abstracting code intricacies is
helpful.
