One of the steps in ODP page fault handler for WQEs is to read a WQE from a QP send queue or receive queue buffer at a specific index. Since the implementation of this buffer is different between kernel and user QP the implementation of the handler needs to be aware of that and handle it in a different way. ODP for kernel MRs is currently supported only for RDMA_READ and RDMA_WRITE operations so change the handler to - read a WQE from a kernel QP send queue - fail if access to receive queue or shared receive queue is required for a kernel QP Signed-off-by: Moni Shoua <monis@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com>
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 Restructured Text 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.
