Associates a counters with a flow when IB_FLOW_SPEC_ACTION_COUNT is part of the flow specifications. The counters user space placements of location and description (index, description) pairs are passed as private data of the counters flow specification. Reviewed-by:

This patch implements the device counters create and destroy APIs and introducing some internal management structures. Downstream patches in this series will add the functionality to support flow counters binding and reading. Reviewed-by:

The struct ib_uverbs_flow_spec_action_count associates a counters object with the flow. Post this association the flow counters can be read via the counters object. Reviewed-by:

A counters object could be attached to flow on creation by providing the counter specification action. General counters description which count packets and bytes are introduced, downstream patches from this series will use them as part of flow counters binding. In addition, increase number of flow specifications supported layers to 10 upon adding count specification and for the previously added drop specification. Reviewed-by:

This patch exposes the read counters verb to user space applications. By that verb the user can read the hardware counters which are associated with the counters object. The application needs to provide a sufficient memory to hold the statistics. Reviewed-by:

Raed Salem authored
The user supplies counters instance and a reference to an output array of uint64_t. The driver reads the hardware counters values and writes them to the output index location in the user supplied array. All counters values are represented as uint64_t types. To be able to successfully read the data the counters must be first bound to an IB object. Downstream patches will present binding method for flow counters. Reviewed-by:

User space application which uses counters functionality, is expected to allocate/release the counters resources by calling create/destroy verbs and in turn get a unique handle that can be used to attach the counters to its counted type. Reviewed-by:

Raed Salem authored
A verbs application may need to get statistics and info on various aspects of a verb object (e.g. Flow, QP, ...), in general case the application will state which object's counters its interested in (we refer to this action as attach), bind this new counters object to the appropriate verb object and on later stage read their values using the counters object. This series introduces a general API for counters object that may accumulate any ib object counters type, bound and read on demand. Counters instance is allocated on an IB context and belongs to that context. Upon successful creation the counters can be bound to a verbs object so that hardware counter instances can be created and read. Downstream patches in this series will introduce the attach, bind and the read functionality. Counters instance can be de-allocated, upon successful destruction the related hardware resources are released. Prior to destroy call the user must first make sure that the counters is not being used by any IB object, e.g. not attached to any of its counted type otherwise an EBUSY error is invoked.

The source e-switch owner allows a vport on one e-switch port be associated with a rule defined on the second port e-switch. The role of the source eswitch owner valid bit in the flow group is to allow the firmware fail driver attempts to wild card the source eswitch match field. If this bit is not set, the firmware ignores the source eswitch owner field totally. Signed-off-by:

Roi Dayan authored
When merged e-switch is supported, the per-port e-switch is logically merged into one e-switch that spans both physical ports and all the VFs. Under merged eswitch, both the matching on source vport and setting destination vport can have a 2nd attribute which is the vhca id of the eswitch owner. For example: esw0: {match: <src vport=1 owner=0> action: fwd to <dst vport=7, owner=1>} is a flow set on eswitch0 matching on source vport=1 from his eswitch and the action being fwd to dest vport=7 of eswitch1.

Technically we hit it a couple of merges ago already if you count all the tag objects, but now it reaches 6M+ objects reachable from HEAD. I was joking around that that's when I should switch to 5.0, because 3.0 happened at the 2M mark, and 4.0 happened at 4M objects.
