Ok, so uio can also be used as an acronym for "user mode I/O". UIO is a thing in of it's self and it not necessarily related to the PRU's in any other way. Other than *someone* back in the era of the beaglebone white wrote a user mode driver using UIO for the PRU's. Anyway, to truly understand what the deal is. I would recommend to you to search the web for anything / everything UIO, and just start reading. The funny thing is that UIO was originally intended to help people create generic PCI card drivers . . . obviously its adapted since. remoteproc ( and rpmsg, etc ) is newer technology, which again really has nothing to do specifically with the PRU. From my understanding of what I've read. remoteproc is really much better used in a situation where you have a generic multi core processor, cores that would normally run Linux. Instead however, remoteproc makes it possible to say run one or more of those cores bare metal. Which quite honestly is a very good thing ( depending ). In my own personal. . . I think they're both great, but that uio is a much better place to be for the beaglebone PRU's. In the future, where teh Begleboard X15 is concerned. remoteproc may actually be the best place to be. Due to the fact that the X15 will have 4 different core types on the single die. Application cores, PRU's IPU's and DSP's . . .
