This patch adds supporting utility functions
for selftest. The intention is to share the self
test code between different drivers.
Supported test cases include:
1. dma_map_single
2. streaming DMA
3. coherent DMA
4. scatter-gather DMA
This seems quite similar to dmatest, any reason why you cannot use/enhance
that?
Dmatest is a standalone kernel module intended for stress testing DMA
engines from userspace with N number of threads and M size combinations etc.
This one; on the other hand, is selftest to verify hardware is working
as expected during power up.
Almost all DMA engine drivers come with some sort of selftest code
called from probe. I followed the same design pattern.
I think the goal is to remove the duplicate self test code in all
drivers over time.
