We would like to start doing some bookkeeping at the beginning, between contexts and at the end of execlists submission. We already mark the beginning and end using EXECLISTS_ACTIVE_USER, to provide an indication when the HW is idle. This give us a pair of sequence points we can then expand on for further bookkeeping. v2: Refactor guc submission to share the same begin/end.

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.
