Tony Nguyen says: ==================== Add RDMA support for Intel IPU E2000 in idpf Tatyana Nikolova says: This idpf patch series is the second part of the staged submission for introducing RDMA RoCEv2 support for the IPU E2000 line of products, referred to as GEN3. To support RDMA GEN3 devices, the idpf driver uses common definitions of the IIDC interface and implements specific device functionality in iidc_rdma_idpf.h. The IPU model can host one or more logical network endpoints called vPorts per PCI function that are flexibly associated with a physical port or an internal communication port. Other features as it pertains to GEN3 devices include: * MMIO learning * RDMA capability negotiation * RDMA vectors discovery between idpf and control plane These patches are split from the submission "Add RDMA support for Intel IPU E2000 (GEN3)" [1]. The patches have been tested on a range of hosts and platforms with a variety of general RDMA applications which include standalone verbs (rping, perftest, etc.), storage and HPC applications.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
