Hi, I was going through the mr.c file as part of understanding WRITE_MTT command in the mlx4 code. I could see that instead of issuing the WRITE_MTT HCR command, in case of SRIOV, we're directly accessing the ICM space for the MTT Table, taking the ownership and updating it. We're doing this using dma_sync_single_for_cpu and dma_sync_single_for_cpu. I was curious as to why this approach was chosen instead of using the HCR command. Can anyone please explain the reason/motivation behind this approach? Thanks so much, Best Regards, Marc -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
