Use of QDMA for ls1046A in linux userspace

[sbozkurt]

Hi,

I developed a device driver in linux kernel space that uses DMA engine and fsl-qdma.c for DMA transfers.

So my question is without device driver that I created is that possible to develop device driver in linux user space that achives DMA transfer using QDMA without the need of developing device driver in kernel space? Or more generally, is that possible to achive DMA transfers from user space without any development in kernel space?

Best Regards...

yes, customer can refer dpdk codes, qdma driver is implemented in dpdk which is user space solution.
