The omapdrm driver uses a custom API to synchronize with the SGX GPU. This is unusable as such in the mainline kernel as the API is only partially implemented and requires additional out-of-tree patches. Furthermore, as no SGX driver is available in the mainline kernel, the API can't be considered as a stable mainline API. Now that the driver supports synchronization through fences, remove legacy buffer synchronization support. The two userspace ioctls are turned into no-ops to avoid breaking userspace and will be removed in the future.

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.
