DMA UserSpace application

NPal.2 · ‎2021-08-02

Hi all,

I am trying to write a linux user-space application where in i am taking data from an external MCU processing it and sending it to another thread. My question here is how can make use of DMA in the user-space to make it more efficient?

How can i eliminate busy looping / waiting for transfer scenarios in user-space?

Thanks,

Nipun Pal
