The fbdev emulation currently uses fbdev's default mmap code, which has been written for I/O memory. Provide an mmap that uses GEM's mmap infrastructure. Utilize fine-grained fbdev macros to initialize struct fb_ops. The macros set the read/write and the draw callbacks for DMA memory. Set the fb_mmap callback to omapdrm's new mmap helper. Also select the correct Kconfig token for fbdev's DMA helpers. Note that the DMA helpers are the same as for system memory.

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.
