Update the counter interface for multiple ports. Some counter sets always comes from the primary device. Port specific counters should be accessed per mlx5_core_dev not always through the IB master mdev. Signed-off-by:

Port operations must be routed to their native mlx5_core_dev. A multiport RoCE device registers itself as having 2 ports even before a 2nd port is affiliated. If an unaffilated port is queried use capability information from the master port, these values are the same. Signed-off-by:

Because mlx5_ib_event can be called from atomic context move event handling onto a workqueue. A mutex lock is required to get the IB device for slave ports, so move event processing onto a work queue. When an IB event is received, check if the mlx5_core_dev is a slave port, if so attempt to get the IB device it's affiliated with. If found process the event for that device, otherwise return.

When mlx5_ib_add is called determine if the mlx5 core device being added is capable of dual port RoCE operation. If it is, determine whether it is a master device or a slave device using the num_vhca_ports and affiliate_nic_vport_criteria capabilities. If the device is a slave, attempt to find a master device to affiliate it with. Devices that can be affiliated will share a system image guid. If none are found place it on a list of unaffiliated ports. If a master is found bind the port to it by configuring the port affiliation in the NIC vport context. Similarly when mlx5_ib_remove is called determine the port type. If it's a slave port, unaffiliate it from the master device, otherwise just remove it from the unaffiliated port list. The IB device is registered as a multiport device, even if a 2nd port is not available for affiliation. When the 2nd port is affiliated later the GID cache must be refreshed in order to get the default GIDs for the 2nd port in the cache. Export roce_rescan_device to provide a mechanism to refresh the cache after a new port is bound. In a multiport configuration all IB object (QP, MR, PD, etc) related commands should flow through the master mlx5_core_dev, other commands must be sent to the slave port mlx5_core_mdev, an interface is provide to get the correct mdev for non IB object commands.

Generate a unique 128bit identifier for each host and pass that value to firmware in the INIT_HCA command if it reports the sw_owner_id capability. Each device bound to the mlx5_core driver will have the same software owner ID. In subsequent patches mlx5_core devices will be bound via a new VPort command so that they can operate together under a single InfiniBand device. Only devices that have the same software owner ID can be bound, to prevent traffic intended for one host arriving at another. The INIT_HCA command length was expanded by 128 bits. The command length is provided as an input FW commands. Older FW does not have a problem receiving this command in the new longer form. Signed-off-by:

There are two potential problems with the existing implementation. 1. Enable and disable can race after the atomic operations. 2. If a command fails the refcount is left in an inconsistent state. Introduce a lock and perform error checking. Fixes: a6f7d2af ("net/mlx5: Add support for multiple RoCE enable") Signed-off-by:

A DC Target (DCT) QP is represented in the hardware as a unique object. This object is created by CREATE_DCT command and destroyed by DESTROY_DCT command. However, in the driver we describe it as a QP. The hardware command that creates a DCT needs parameters that the verb create_qp() does not provide. Those remaining parameters are provided with the call to the verb modify_qp(). Therefore we delay the actual creation of a DCT in the hardware until the stage of modify_qp() to RTR. A support for query_qp() was added as well. It uses QUERY_DCT command to retrieve the applicable fields. Signed-off-by:

DC Initiator (DCI) QP is represented like any other QP in the hardware. However, like any other transport QP there are attributes and settings that are special to DCI QP and needs specific attention and care. Make necessary changes to configure DCI QP. Signed-off-by:

Moni Shoua authored
The QP type IB_QPT_DRIVER doesn't describe the transport or the service that the QP provides but those are known only to the hardware driver. The actual type of the QP is stored in the hardware driver context (i.e. mlx5_qp) under the field qp_sub_type. Take the real QP type and any extra data that is required to create the QP from the driver channel and modify the QP initial attributes before continuing with create_qp(). Downstream patches from this series will add support for both DCI and DCT driver QPs. Signed-off-by:
-
Moni Shoua authored
Vendors can implement type of QPs that are not described in the InfiniBand specification. To still be able to use the IB/core layer services (e.g. user object management) without tainting this layer with driver proprietary logic, a new QP type is added - IB_QPT_DRIVER. This will be a general QP type that the core layer doesn't know about its true nature. When a command like create_qp() is passed to a hardware driver the extra data that is required is taken from the driver channel. Downstream patches from this series will use that QP type in the mlx5 driver. Signed-off-by:

Reporting that a device doesn't support RoCE seems like a valuable piece of information to have when trying to determine why a driver is not binding to a device. Better to report this at info log level instead of requiring a user to enable all debug messages in the driver. Signed-off-by:

This patch adds static trace for RNRNAK timer. Currently the output from hrtimer static trace only shows the addresses of hrtimers in the system and there is no easy way to correlate an RNRNAK timer with its entries in the hrtimer trace. This patch adds the correlation among a QP, its RNRNAK timer, and its entries in the hrtimer trace. This correlation will be enormously helpful when debugging RNRNAK related issues. In addition, this patch cleans up rvt_stop_rnr_timer() to be void while here. Reviewed-by:

The get_unit_name() function crafts a string based on the device name and the device unit number. It then stores this in a static variable. This has concurrency issues as can be seen with this log: hfi1 0000:02:00.0: hfi1_1: read_idle_message: read idle message 0x203 hfi1 0000:01:00.0: hfi1_1: read_idle_message: read idle message 0x203 The PCI device ID (0000:02:00.0 vs. 0000:01:00.0) is correct for the message, but the device string hfi1_1 is incorrect (it should be hfi1_0 for the second log message). Remove get_unit_name() function. Instead, use the rvt accessor rvt_get_ibdev_name() to get the IB name string. Clean up any hfi1_early_xx calls that can now use the new path. QIB has the same (qib_get_unit_name()) issue. Updating as necessary. Remove qib_get_unit_name() function. Update log message that has redundant device name. Reviewed-by:

CQ allocation does not ensure that completion queue entries and the completion queue structure are allocated on the correct numa node. Fix by allocating the rvt_cq and kernel CQ entries on the device node, leaving the user CQ entries on the default local node. Also ensure CQ resizes use the correct allocator when extending a CQ.

When an 8051 command times out, the entire DC block is restarted. During the restart, the host interface version bit is set, which calls do_8051_command() recursively. The host version bit needs to be set before the link moves into polling, so the host version bit can be set in set_local_link_attributes() instead. Thus, the 8051 command functions can be simplied as a non-locking version (dd->dc8051_lock) of those functions are no longer needed.
