dmatest: Simple DMA memcpy test client
This client tests DMA memcpy using various lengths and various offsets into the source and destination buffers. It will initialize both buffers with a repeatable pattern and verify that the DMA engine copies the requested region and nothing more. It will also verify that the bytes aren't swapped around, and that the source buffer isn't modified. The dmatest module can be configured to test a specific device, a specific channel. It can also test multiple channels at the same time, and it can start multiple threads competing for the same channel. Changes since v2: * Support testing multiple channels at the same time * Support testing with multiple threads competing for the same channel * Use counting test patterns in order to catch byte ordering issues Changes since v1: * Remove extra dashes around "help" * Remove "default n" from Kconfig * Turn TEST_BUF_SIZE into a module parameter * Return DMA_NAK instead of DMA_DUP * Print unhandled events * Support testing specific channels and devices * Move to the end of the Makefile Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
