DMA write: size of the data larger than 2KB #69

Closed wawade closed 6 years ago

wawade commented 6 years ago

Hello, I have a problem when I call ib_write_lat with data size larger than 2KB. Then the program will be blocked with no return. But for ibv_rc_pingpong, the problem does not exist. So I am wondering if write DMA is correct for softRoce or some special configuration is necessary. Similar DMA write problem can be viewed also in my application. I am looking forward to your reply.
