The DMA peripheral is used to perform memory transfers in parallel to the work of the processor (the execution of the main program). A DMA transfer is more or less equivalent to spawning a thread (see thread::spawn) to do a memcpy. We'll use the fork-join model to illustrate the requirements of a memory safe API.

2025年2月7日 · 该系列添加了一个小的Rust模块，为驱动程序提供了足够的支持来设置一致性映射（在缓存一致性内存中的长期映射）。 这项工作只涵盖了DMA API的一部分，但对于较简单的设备来说已经足够。 即将推出的驱动程序将需要这些抽象接口到位。 然而， Christoph Hellwig （他在DMA映射层方面做了大量工作）拒绝了这一提交，并附上了完整的消息：“请不要在内核/dma中添加Rust代码”（尽管该补丁并未在该目录中添加任何代码）。 在被追问时，他补充说，开发者 …

A little DMA cheat for Rust. Some basic functions. A basic and easy to update SDK. As Facepunch are claiming to take a heavier stance against content that infringes upon their copyright; I have removed the images of the cheat from the repo. It no longer contains any media from their game, therefore no more copyrighted material.
