The kernel and user create QP flows have very little common code, separate them to simplify the future work of creating per-type create_*_qp() functions. Link: https://lore.kernel.org/r/20200427154636.381474-29-leon@kernel.orgReviewed-by:

XRC_TGT QP doesn't fail into kernel or user flow separation. It is initiated by the user, but is created through in-kernel verbs flow and doesn't have PD and udata in similar way to kernel QPs. So let's separate creation of that QP type from the common flow. Link: https://lore.kernel.org/r/20200427154636.381474-28-leon@kernel.orgReviewed-by:

Instead of keeping special field to separate kernel/user create/destroy flows, rely on existence of udata pointer. All allocation flows are using kzalloc() and leave uninitialized pointers as NULL which makes MLX5_QP_EMPTY and MLX5_QP_KERNEL flows to be the same.

QP type is stored in the IB/core QP struct, but it doesn't have all the needed information, like internal QP type used in the driver itself. Update mlx5_ib to have cached QP type which includes both IBTA and Mellanox specific one. Such change allows us to make even further cleanup of QP creation flow.

Leon Romanovsky says: ==================== This is first part of series which tries to return some sanity to mlx5_ib_create_qp() function. Such refactoring is required to make extension of that function with less worries of breaking driver. Extra goal of such refactoring is to ensure that QP is allocated at the beginning of function and released at the end. It will allow us to move QP allocation to be under IB/core responsibility. ==================== Based on the mlx5-next branch at git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Due to dependencies * branch 'mlx5_ib_qp_refactor_1': (66 commits) RDMA/mlx5: Process all vendor flags in one place RDMA/mlx5: Return all configured create flags through query QP RDMA/mlx5: Change scatter CQE flag to be set like other vendor flags RDMA/mlx5: Use flags_en mechanism to mark QP created with WQE signature RDMA/mlx5: Process create QP flags in one place RDMA/mlx5: Delete create QP flags obfuscation RDMA/mlx5: Initial separation of RAW_PACKET QP from common flow RDMA/mlx5: Remove second copy from user for non RSS RAW QPs RDMA/mlx5: Move DRIVER QP flags check into separate function RDMA/mlx5: Update all DRIVER QP places to use QP subtype RDMA/mlx5: Split scatter CQE configuration for DCT QP RDMA/mlx5: Separate create QP flows to be based on type RDMA/mlx5: Set QP subtype immediately when it is known RDMA/mlx5: Avoid setting redundant NULL for XRC QPs RDMA/mlx5: Prepare QP allocation for future removal RDMA/mlx5: Perform check if QP creation flow is valid RDMA/mlx5: Delete impossible GSI port check RDMA/mlx5: Organize QP types checks in one place Signed-off-by:

MLX5_QP_FLAG_SIGNATURE is exposed to the users but in the kernel the create_qp flow treated it differently from other MLX5_QP_FLAG_*s. Fix it by ditching wq_sig boolean variable and use general flag_en mechanism. Link: https://lore.kernel.org/r/20200427154636.381474-16-leon@kernel.orgReviewed-by:

create_flags is checked in too many places and scattered across all the code, consolidate all the checks inside one function, so we will be easily see the flow. As part of such change, delete unreachable code, because IB/core is responsible sanitize the input. Link: https://lore.kernel.org/r/20200427154636.381474-15-leon@kernel.orgReviewed-by:

There is no need to delay QP subtype assignment to the end of the create_qp() function and it is better to move it to be immediately after it is checked so we would be able to rewrite later checks to be based on it and not on over-written struct ib_qp_init_attr.
