* IB/core: Fix typo in the name of the tag-matching cap structLeon Romanovsky2017-09-251-1/+1
| | | | | | | | | | | | | The tag matching functionality is implemented by mlx5 driver by extending XRQ, however this internal kernel information was exposed to user space applications with *xrq* name instead of *tm*. This patch renames *xrq* to *tm* to handle that.

* IB/core: Add completion queue (cq) object actionsMatan Barak2017-08-311-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding CQ ioctl actions: 1. create_cq 2. destroy_cq This requires adding the following: 1. A specification describing the method a. Handler b. Attributes specification Each attribute is one of the following: a. PTR_IN - input data Note: This could be encoded inlined for data < 64bit b. PTR_OUT - response data c. IDR - idr based object d. FD - fd based object Blobs attributes (clauses a and b) contain their type, while objects specifications (clauses c and d) contains the expected object type (for example, the given id should be UVERBS_TYPE_PD) and the required access (READ, WRITE, NEW or DESTROY). If a NEW is required, the new object's id will be assigned to this attribute. All attributes could get UA_FLAGS attribute. Currently we support stating that an attribute is mandatory or that the specification size corresponds to a lower bound (and that this attribute could be extended). We currently add both default attributes and the two generic UHW_IN and UHW_OUT driver specific attributes. 2. Handler A handler gets a uverbs_attr_bundle. The handler developer uses uverbs_attr_get to fetch an attribute of a given id. Each of these attribute groups correspond to the specification group defined in the action (clauses 1.b and 1.c respectively). The indices of these arrays corresponds to the attribute ids declared in the specifications (clause 2). The handler is quite simple. It assumes the infrastructure fetched all objects and locked, created or destroyed them as required by the specification. Pointer (or blob) attributes were validated to match their required sizes. After the handler finished, the infrastructure commits or rollbacks the objects.

* IB/core: Add legacy driver's user-dataMatan Barak2017-08-311-0/+10
| | | | | | | | | | | | | | | | | In this phase, we don't want to change all the drivers to use flexible driver's specific attributes. Therefore, we add two default attributes: UHW_IN and UHW_OUT. These attributes are optional in some methods and they encode the driver specific command data. We add a function that extract this data and creates the legacy udata over it. Driver's data should start from UVERBS_UDATA_DRIVER_DATA_FLAG. This turns on the first bit of the namespace, indicating this attribute belongs to the driver's namespace.

* IB/core: Add new ioctl interfaceMatan Barak2017-08-311-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this ioctl interface, processing the command starts from properties of the command and fetching the appropriate user objects before calling the handler. Parsing and validation is done according to a specifier declared by the driver's code. In the driver, all supported objects are declared. These objects are separated to different object namepsaces. Dividing objects to namespaces is done at initialization by using the higher bits of the object ids. This initialization can mix objects declared in different places to one parsing tree using in this ioctl interface. For each object we list all supported methods. Similarly to objects, methods are separated to method namespaces too. Namespacing is done similarly to the objects case. This could be used in order to add methods to an existing object. Each method has a specific handler, which could be either a default handler or a driver specific handler. Along with the handler, a bunch of attributes are specified as well. Similarly to objects and method, attributes are namespaced and hashed by their ids at initialization too. All supported attributes are subject to automatic fetching and validation. These attributes include the command, response and the method's related objects' ids. When these entities (objects, methods and attributes) are used, the high bits of the entities ids are used in order to calculate the hash bucket index. Then, these high bits are masked out in order to have a zero based index. Since we use these high bits for both bucketing and namespacing, we get a compact representation and O(1) array access. This is mandatory for efficient dispatching. Each attribute has a type (PTR_IN, PTR_OUT, IDR and FD) and a length. Attributes could be validated through some attributes, like: (*) Minimum size / Exact size (*) Fops for FD (*) Object type for IDR If an IDR/fd attribute is specified, the kernel also states the object type and the required access (NEW, WRITE, READ or DESTROY). All uobject/fd management is done automatically by the infrastructure, meaning - the infrastructure will fail concurrent commands that at least one of them requires concurrent access (WRITE/DESTROY), synchronize actions with device removals (dissociate context events) and take care of reference counting (increase/decrease) for concurrent actions invocation. The reference counts on the actual kernel objects shall be handled by the handlers. objects +--------+ | | | | methods +--------+ | | ns method method_spec +-----+ |len | +--------+ +------+[d]+-------+ +----------------+[d]+------------+ |attr1+-> |type | | object +> |method+-> | spec +-> + attr_buckets +-> |default_chain+--> +-----+ |idr_type| +--------+ +------+ |handler| | | +------------+ |attr2| |access | | | | | +-------+ +----------------+ |driver chain| +-----+ +--------+ | | | | +------------+ | | +------+ | | | | | | | | | | | | | | | | | | | | +--------+ [d] = Hash ids to groups using the high order bits The right types table is also chosen by using the high bits from the ids. Currently we have either default or driver specific groups. Once validation and object fetching (or creation) completed, we call the handler: int (*handler)(struct ib_device *ib_dev, struct ib_uverbs_file *ufile, struct uverbs_attr_bundle *ctx); ctx bundles attributes of different namespaces. Each element there is an array of attributes which corresponds to one namespaces of attributes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new defines to rdma_netlink.h, so the RDMA configuration tool will be able to communicate with RDMA subsystem by using the shared defines. The addition of new client (NLDEV) revealed the fact that we exposed by mistake the RDMA_NL_I40IW define which is not backed by any RDMA netlink by now and it won't be exposed in the future too. So this patch reuses the value and deletes the old defines. The NLDEV operates with objects. The struct ib_device has two straightforward objects: device itself and ports of that device. This brings us to propose the following commands to work on those objects: * RDMA_NLDEV_CMD_{GET,SET,NEW,DEL} - works on ib_device itself * RDMA_NLDEV_CMD_PORT_{GET,SET,NEW,DEL} - works on ports of specific ib_device Those commands receive/return the device index (RDMA_NLDEV_ATTR_DEV_INDEX) and port index (RDMA_NLDEV_ATTR_PORT_INDEX). For device object accesses, the RDMA_NLDEV_ATTR_PORT_INDEX will return the maximum number of ports for specific ib_device and for port access the actual port index. The port index starts from 1 to follow RDMA/core internal semantics and the sysfs exposed knobs.

The base IB object to enable RSS functionality is a WQ (i.e. ib_wq). This patch implements the related WQ verbs as of create, modify and destroy. In downstream patches the WQ will be used as part of an indirection table (i.e. ib_rwq_ind_table) to enable RSS QP creation. Notes: ConnectX-3 hardware requires consecutive WQNs list as receive descriptor queues for the RSS QP. Hence, the driver manages consecutive ranges lists per context which the user must respect. Destroying the WQ does not return its WQN back to its range for reusing. However, destroying all WQs from the same range releases the range and in turn releases its WQNs for reusing. Since the WQ object is not a natural object in the hardware, the driver implements the WQ by the hardware QP. As such, the WQ inherits its port from its RSS QP parent upon its RST->INIT transition and by that time its state is applied to the hardware.
