Rust in V4L2: a status report
summary
A patchset with initial Rust patchset yields Rust abstractions for V4L2: vb2 queue/allocations, V4L2 ioctls and format enumeration, device probe and a sample module that prints when an ioctl is processed. The proposal builds a virtual stateless codec driver (viso-like, minus debug hooks) to exercise M2M, media-controller and vb2 abstractions so real drivers can reuse them. Maintainers raise review bandwidth and C API lifetime concerns; mitigation includes compile-time detection, experimental Kconfig, a Collabora maintenance branch and an offered maintainer commitment.
