net/mlx5: Set software owner ID during init HCA

2018-01-08T18:42:20+00:00

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.

IB/mlx5: Extend UAR stuff to support dynamic allocation

2017-12-28T18:33:14+00:00

This patch extends the alloc context flow to be prepared for working with dynamic UAR allocations. Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed. Downstream patches from this series will enable the dynamic allocation and the association as part of QP creation.
