Best way to implement dynamic memory allocation for DMA transfers

[danieldanino17]

Hi, I'm new to Zephyr and I'm trying to figure out the best way to implement dynamic memory allocation for DMA transfers.

I've seen that Zephyr offers several ways to allocate memory dynamically, but it's a bit overwhelming and I'm not sure which approach is suitable for DMA.

All the DMA examples I’ve come across use statically allocated arrays, and I haven’t found any that demonstrate dynamic memory allocation.

I'm interested in how to handle both contiguous and scatter-gather memory allocations for DMA. Any guidance or examples would be greatly appreciated.
