Abstract
The disclosed embodiments provide a system that uses a DMA engine to automatically validate DMA data paths for a computing device. During operation, the system configures the DMA engine to perform a programmable DMA operation that generates a sequence of memory accesses which validate the memory subsystem and DMA paths of the computing device. For instance, the operation may include a sequence of reads and/or writes that generate sufficient data traffic to exercise the computing device's I/O controller interface and DMA data paths to memory to a specified level. The system initiates this programmable DMA operation, and then checks outputs for the operation to confirm that the operation executed successfully.
