HIDMA HW supports memset operation in addition to memcpy. Since the memset API is present on the kernel now, bring the memset feature into life. The descriptor format is the same for both memcpy and memset. Type of the descriptor is 4 when memset is requested. The lowest 8 bits of the source DMA argument is used as a fill pattern.

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.
