[$] What the Nova GPU driver needs

In March, Danilo Krummrich announced the new
Nova GPU driver — a successor to Nouveau for controlling NVIDIA GPUs.
At Kangrejos 2024, Krummrich gave a
presentation about what it is, why it's needed, and where it's
going next. Hearing about the needs of the driver provoked extended discussion
on related topics, including what level of safety is reasonable to expect from
drivers, given that they must interact with the hardware.
