This patch extends HCA_CAP and SQ Context structs available in PRM. This fields allow checking if NIC supports storing hairpin SQ's WQ buffer in host memory and configuring such memory placement. HCA capabilities are extended with the following fields: - hairpin_sq_wq_in_host_mem - If set, then NIC supports using host memory as a backing storage for hairpin SQ's WQ buffer. - hairpin_sq_wqe_bb_size - Indicates the required size of SQ WQE basic block. SQ Context is extended with hairpin_wq_buffer_type which informs NIC where SQ's WQ buffer will be stored. This field can take the following values: - MLX5_SQC_HAIRPIN_WQ_BUFFER_TYPE_INTERNAL_BUFFER - WQ buffer will be stored in unlocked device memory. - MLX5_SQC_HAIRPIN_WQ_BUFFER_TYPE_HOST_MEMORY - WQ buffer will be stored in host memory. Buffer is provided by PMD. Signed-off-by: Dariusz Sosnowski <dsosnowski@nvidia.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com> |
