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
