From: Saeed Mahameed <hidden>
Date: 2016-10-25 15:05:43
Also in:
linux-rdma
Subsystem:
mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, the rest · Maintainers:
Leon Romanovsky, Saeed Mahameed, Tariq Toukan, Mark Bloch, Linus Torvalds
From: Artemy Kovalyov <redacted>
Add to struct mlx5_ifc_cmd_hca_cap_bits capability bits
indicating related value/field is supported:
* fixed_buffer_size - MLX5_MKC_ACCESS_MODE_KSM
* umr_extended_translation_offset -translation_offset_42_16
in UMR ctrl segment
* null_mkey - null_mkey in QUERY_SPECIAL_CONTEXTS
Add MLX5_MKC_ACCESS_MODE_KSM enum value
Add null_mkey field to struct mlx5_ifc_query_special_contexts_out_bits
