In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.

For example, users might want to restrict the driver to some specified subset of the cores so that they can appropriately partition processes, irq handlers, and work threads. To allow the user to fine tune system affinity settings new sysfs attributes are introduced per sdma engine. This patch adds a new attribute type for sdma engine and a new cpu_list attribute. When the user writes a cpu range to the cpu_list attribute the driver will create an internal cpu->sdma map, which will be used later as a look-up table to choose an optimal engine for a user requests.

A packet causes a defered ack to be pended by putting the QP into an rcd queue. A return from the driver interrupt processing will process that rcd queue of QPs and attempt to do a direct send of the ack. At this point no locks are held and the above QP could now be put in the reset state in the qp destroy logic. A refcount protects the QP while it is in the rcd queue so it isn't going anywhere yet. If the direct send fails to allocate a pio buffer, hfi1_schedule_send() is called to trigger sending an ack from the send engine. There is no state test in that code path. The refcount is then dropped from the driver.c caller potentially allowing the qp destroy to continue from its refcount wait in parallel with the workqueue scheduling of the qp.

When a relatively large number of QPs (within that range) is used, the test can fail because the number of CQ entries needed exceeds the limit set by the driver. This patch increases the default setting of max_cqes from 0x2FFFF (196607) to 0x2FFFFF(3145727), which is sufficient to cover the maximum number needed by the ib_write_bw test (2097152). The default setting of max_qps is also increased from 16384 to 32768 to allow the test to run successfully with 16383 or 16384 QPs.

We acquire the lock to get hfi1_affinity_node entry, unlock, and then use the entry without the lock held. With more functions being added, which access and modify the entries, this can lead to race conditions. This patch makes this locking scheme more consistent. It changes the spinlock to mutex. Since all the code is executed in a user process context there is no need for a spinlock. This also allows to keep the lock not only while we look up for the node affinity entry, but over the whole section where the entry is being used.

Each user packet may use multiple SDMA descriptors to fill the send buffer. The field seqsubmitted in struct user_sdma_request counts the number of user packets submitted to an SDMA engine. Sometimes, the intermediate count may not be updated properly. However, once all the packets' descriptors are successfully submitted to the SDMA engine, the final count is updated correctly. But, if only some of the packets are submitted to the engine due to an error, the intermediate count doesn't reflect the partial number of packets submitted to the SDMA engine. This can cause a hang later in the code as the count of packets submitted to the SDMA engine doesn't match the the count of packets processed by the SDMA engine.
