MUSE: MTD in Userspace, or How to Extend FUSE for Fun and Profit

on YouTube ↗36m

" summary

A new interface called MUSE: MTD in userspace extends FUSE to expose MTD drivers in userspace, implementing MTD operations over the FUSE request/response protocol. It demonstrates a userspace UBI/UBIFS simulator for testing, shows how to map kernel MTD ops to FUSE messages, and describes handling concurrent writes, partitioning, and crash testing with four test images. Code hooks and the exact request/structure mappings needed to build this are shown.
