We modify the signature API to allow usage of some new execution parameters relevant to data integrity feature. This patch modifies ib_sig_domain structure by: - Deprecate DIF type in signature API (operation will be determined by the parameters alone, no DIF type awareness) - Add APPTAG check bitmask (for input domain) - Add REFTAG remap (increment) flag for each domain - Add APPTAG/REFTAG escape options for each domain The mlx5 driver is modified to follow the new parameters in HW signature setup. At the moment the callers (iser/isert) hard-code new parameters (by DIF type). In the future, callers will retrieve them from the scsi command structure.

* | mlx5: Move pci device handling from mlx5_ib to mlx5_coreJack Morgenstein2014-07-307-305/+196Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for a new mlx5 device which is VPI (i.e., ports can be either IB or ETH), move the pci device functionality from mlx5_ib to mlx5_core. This involves the following changes: 1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev is now an independent structure maintained by mlx5_core. mlx5_ib_dev now has a pointer to that struct. This requires changing a lot of places where the core_dev struct was accessed via mlx5_ib_dev (now, this needs to be a pointer dereference). 2. All PCI initializations are now done in mlx5_core. Thus, it is now mlx5_core which does pci_register_device (and not mlx5_ib, as was previously). 3. mlx5_ib now registers itself with mlx5_core as an "interface" driver. This is very similar to the mechanism employed for the mlx4 (ConnectX) driver. Once the HCA is initialized (by mlx5_core), it invokes the interface drivers to do their initializations. 4. There is a new event handler which the core registers: mlx5_core_event(). This event handler invokes the event handlers registered by the interfaces.

| * IB/mlx5: Support IB_WR_REG_SIG_MRSagi Grimberg2014-03-071-0/+422
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements IB_WR_REG_SIG_MR posted by the user. Baisically this WR involves 3 WQEs in order to prepare and properly register the signature layout: 1. post UMR WR to register the sig_mr in one of two possible ways: * In case the user registered a single MR for data so the UMR data segment consists of: - single klm (data MR) passed by the user - BSF with signature attributes requested by the user. * In case the user registered 2 MRs, one for data and one for protection, the UMR consists of: - strided block format which includes data and protection MRs and their repetitive block format. - BSF with signature attributes requested by the user. 2. post SET_PSV in order to set the memory domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. 3. post SET_PSV in order to set the wire domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. * After this compound WR we place a small fence for next WR to come. This patch also introduces some helper functions to set the BSF correctly and determining the signature format selectors.

| | | | | | | | | | | | | | | | | | | | | | get_umr_flags helper function might be used for types of access modes other than ACCESS_MODE_MTT, such as ACCESS_MODE_KLM. So remove it from helper, and callers will add their own access mode flag. This commit does not add/change functionality.

| * IB/mlx5: Initialize mlx5_ib_qp signature-related membersSagi Grimberg2014-03-072-3/+12
| | | | | | | | | | | | | | | | | | | | | | If user requested signature enable we initialize relevant mlx5_ib_qp members. We mark the qp as sig_enable and we increase the effective SQ size, but still limit the user max_send_wr to original size computed. We also allow the create_qp routine to accept sig_enable create flag. Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
| * mlx5: Implement create_mr and destroy_mrSagi Grimberg2014-03-073-0/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support create_mr and destroy_mr verbs. Creating ib_mr may be done for either ib_mr that will register regular page lists like alloc_fast_reg_mr routine, or indirect ib_mrs that can register other (pre-registered) ib_mrs in an indirect manner. In addition user may request signature enable, that will mean that the created ib_mr may be attached with signature attributes (BSF, PSVs). Currently we only allow direct/indirect registration modes.

| | | | | | | | | | | | | | | | | | | | | | This patch refactors the IB core umem code and vendor drivers to use a linear (chained) SG table instead of chunk list.

* IB/mlx5: Fix binary compatibility with libmlx5Eli Cohen2014-02-073-4/+32
| | | | | | | | | | | | | | | | Commit c1be5232d21d ("Fix micro UAR allocator") broke binary compatibility between libmlx5 and mlx5_ib since it defines a different value to the number of micro UARs per page, leading to wrong calculation in libmlx5. This patch defines struct mlx5_ib_alloc_ucontext_req_v2 as an extension to struct mlx5_ib_alloc_ucontext_req. The extended size is determined in mlx5_ib_alloc_ucontext() and in case of old library we use uuarn 0 which works fine -- this is acheived due to create_user_qp() falling back from high to medium then to low class where low class will return 0. For new libraries we use the more sophisticated allocation algorithm.

When dealing with L2 Ethernet, we should use smac, dmac, vlan ID and priority in a similar manner that the IB L2 (and the L4 PKEY) attributes are used. Thus, those attributes were added to the following structures: * ib_ah_attr - added dmac * ib_qp_attr - added smac and vlan_id, (sl remains vlan priority) * ib_wc - added smac, vlan_id * ib_sa_path_rec - added smac, dmac, vlan_id * cm_av - added smac and vlan_id For the path record structure, extra care was taken to avoid the new fields when packing it into wire format, so we don't break the IB CM and SA wire protocol. On the active side, the CM fills. its internal structures from the path provided by the ULP. We add there taking the ETH L2 attributes and placing them into the CM Address Handle (struct cm_av). On the passive side, the CM fills its internal structures from the WC associated with the REQ message. We add there taking the ETH L2 attributes from the WC. When the HW driver provides the required ETH L2 attributes in the WC, they set the IB_WC_WITH_SMAC and IB_WC_WITH_VLAN flags. The IB core code checks for the presence of these flags, and in their absence does address resolution from the ib_init_ah_from_wc() helper function. ib_modify_qp_is_ok is also updated to consider the link layer. Some parameters are mandatory for Ethernet link layer, while they are irrelevant for IB. Vendor drivers are modified to support the new function signature.
