Today we have single function which is used when we add an IB interface, break this function into multiple functions. Create stages and a generic mechanism to execute each stage. This is in preparation for RDMA/IB representors which might not need all stages or will do things differently in some of the stages. This patch doesn't change any functionality. Signed-off-by:

When debugging issues with RC QPs, it is useful to know if a QP has an associated RQ or SRQ, the size of the RQ, and any RNR timeout values. Add the necessary information to the QP stats output. Reviewed-by:

It needs to create eight reserve QPs for resolving a bug of hip06. When deregistering mr, it will issue a rdma write for every reserve QPs. When modify qp from init to rtr, it needs to set the value of dest_qp_num. Otherwise, it will lead an error of freeing mr. Signed-off-by:

This patch fixes the usage with sr_max filed and rr_max of qp context when modify qp. Its modifications include: 1. Adjust location of filling sr_max filed of qpc 2. Only assign the number of responder resource if IB_QP_MAX_DEST_RD_ATOMIC bit is set 3. Only assign the number of outstanding resource if IB_QP_MAX_QP_RD_ATOMIC 4. Fix the assgin algorithms for the field of sr_max and rr_max of qp context Signed-off-by:

This patch exposes the option to dynamic allocates a UAR, this functionality will be used in downstream patch in this series as part of QP creation. Specifically, the user space driver asks for a UAR allocation in a given page index, upon success this UAR and its bfregs can be used as part of QP creation by the user space driver. To enable allocating more than 256 UARs the page index is encoded in an extra one byte just after the command byte. Signed-off-by:

This patch extends the alloc context flow to be prepared for working with dynamic UAR allocations. Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed. Downstream patches from this series will enable the dynamic allocation and the association as part of QP creation. Signed-off-by:

ibmr.device is being set only after ib_alloc_mr() is (successfully) complete. Therefore, in case mlx5_core_create_mkey() return with error, the error flow calls mlx5_free_priv_descs() which uses ibmr.device (which doesn't exist yet), causing a NULL dereference oops. To fix this, the IB device should be set in the mr struct earlier stage (e.g. prior to calling mlx5_core_create_mkey()).
