Giving Rust a chance for in-kernel codecs

This talk will show how it is possible to write Rust code in the kernel without a binding layer, and how this drastically reduces the number of Rust abstractions needed, with a focus on V4L2 codec drivers and  libraries. It will present a strategy wherein only a few critical functions are converted to Rust while accounting for the role of the “cbindgen” tool in keeping ABI compatibility. The source code of a previously submitted proof-of-concept will be used to provide examples.
