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. > > > and some info > > on kernel internals with respect to the booting > > process, scheduling/migration etc. > > > > I've been looking around for relevant documenta- > > tion but found little to none. > > Is the code not enough documentation for you for doing your porting > work?
