Now that we have fast top-down insertion into the drm_mm, we can use it for frequent runtime operations like insertion of the context object, whereas before we limited it to the one-off insertion of the pinned kernel context. Keeping the active context objects out of the mappable region of the global GTT (except under memory pressure) improves our ability to allocate mappable aperture region without triggering a GPU stall.

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.
