[$] Getting PCI driver abstractions upstream

Danilo Krummrich gave a talk at Kangrejos 2024 focusing on the question of howthe Rust-for-Linux project could improve at getting device and driverabstractions upstream. As a case study, he used some of his recent work thatattempts to make it possible to write a PCI driver entirely in Rust. Therewasn't time to go into as much detail as he would have liked, but he diddemonstrate that it is possible to interface with the kernel's module loader ina way that is much harder toscrew up than the current standard approach in C.
