evaluate ETH DMA design #84

Use VolatileCell along the lines of stb32-usbd and check what evolves around best practices of DMA/uninit, (MaybeUninit, compiler_fence).

@jordens I believe this can be closed since we're using stm32h7-ethernet

jordens commented 4 years ago

I don't think so. stm32h7-ethernet doesn't mark the descriptors as VolatileCells either. It doesn't differ from my old code in that respect AFAICT.

ryan-summers commented 4 years ago

What I mean is that this issue isn't necessary suitable for this repository anymore, but rather the linked stm32h7x-ethernet crate since we don't implement any ethernet DMA functionality here after the HAL refactor.

jordens commented 4 years ago

Oh yes. Right. Somebody with a sound understanding of this should move it over to stm32h7-ethernet if appropriate.
