While the Intel HW may not existing til 2006. A number of embedded SoC processors have had general purpose DMA engines on them for some time that these APIs may be useful for.

Indeed, in a previous life I had to implement a generic DMA api for the SH4 family of processors for use by things like IDE controllers. I even implemented a user space interface for controlling DMA for user-space apps.

ppc4xx is one example - ppc4xx_dma is in need of a reworking anyway. I've recently discovered this in implementing DMA support for MTD devices - having a generic DMA engine API would also help here.

Side note: I love it when people start talking about amazingly cool technology that Intel apparently will revolutionise the world with, when it's been done for years and years already :-)
