Currently ODP MR may explicitly register virtual address space area of limited length. This change allows MR to cover entire process virtual address space dynamicaly adding/removing translation entries to device MTT. Add following changes to support implicit MR: * Allow umem to be zero size to back-up implicit MR. * Add new function ib_alloc_odp_umem() to add virtual memory regions to implicit MR dynamically on demand. * Add new function rbt_ib_umem_lookup() to find dynamically added virtual memory regions. * Expose function rbt_ib_umem_for_each_in_range() to other modules and make it safe Signed-off-by: Artemy Kovalyov <artemyko@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
