Hello, I use ddi_dma_mem_alloc to allocate receive ring buffer and set device register the physical address of these receive buffer. After writing data to the receive buffer, the device will send a message to host the physical address where the received data was written(in host memory pre-allocated receive ring buffer). Right now, there are some strange issues, so, I want to verify whether device writes to correct address.
I am wondering if it is possible to map physical address back to virtual? Wendy This message posted from opensolaris.org _______________________________________________ networking-discuss mailing list [email protected]
