My project requires high DMA speeds even when the device is down with no connections. Right now I have tried and got around 20-30MB/s or read fails. This is not enough, and with another card I was getting about 200MB/s. Is there anywhere in the driver source code that could be limiting/blocking the DMA reads that is controlled by the device's memory mapped space? I have looked so far and have only found logic that controls DMA while the device is active with a connection.
Thanks.
