From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Changelog v0->v1: * Decouple from DevX submission * Use uverbs_attr_get_obj at counters read method * Added define for max read buffer size (MAX_COUNTERS_BUFF_SIZE) * Removed the struct mlx5_ib_flow_counter basic_flow_cnts and the related structs used, used define instead * Took Matan's patch from DevX * uverbs_free_counters removed void* casting * Added check to bound ncounters value (added define * Changed user supplied data buffer structure to be array of struct <desc,index> pair (applied this change to user space also) Not changed: * UAPI files * Addition of uhw to flow Thanks ---------------------------------------------------------------------- >From Raed: This series comes to allow user space applications to monitor real time traffic activity and events of the verbs objects it manages, e.g.: ibv_qp, ibv_wq, ibv_flow. This API enables generic counters creation and define mapping to association with a verbs object, current mlx5 driver using this API for flow counters. With this API, an application can monitor the entire life cycle of object activity, defined here as a static counters attachment. This API also allows dynamic counters monitoring of measurement points for a partial period in the verbs object life cycle. In addition it presents the implementation of the generic counters interface. This will be achieved by extending flow creation by adding a new flow count specification type which allows the user to associate a previously created flow counters using the generic verbs counters interface to the created flow, once associated the user could read statistics by using the read function of the generic counters interface. The API includes: 1. create and destroyed API of a new counters objects 2. read the counters values from HW Note: Attaching API to allow application to define the measurement points per objects is a user space only API and this data is passed to kernel when the counted object (e.g. flow) is created with the counters object.
