The upstream mlx4 driver does not support reg_phys_mr. Are there any plans to add support for this verb?
The reg_phys_mr verb was made optional a while back: http://lists.openfabrics.org/pipermail/general/2008-April/048715.html making dma_mr the only required kernel memory registration mode. As a result, kernel ULPs don't have a guaranteed mechanism for creating MRs of limited size and fine-grained permissions since both reg_phys_mr and fast_reg_mr are optional. Since all HW providers except mlx4 support reg_phys_mr, providing a reg_phys_mr implementation would fix this. -james _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
