Linux for the Switch

When running in software cyclic mode the driver currently does not go back to the first segment once the last segment has been reached. Effectively making the transfer non-cyclic. Fix this by going back to the first segment once the last segment has been reached for cyclic transfers. Special care need to be taken to avoid a segment from being submitted multiple times concurrently, which could happen for transfers with a number of segments that is smaller than the DMA controller's internal queue.

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.
