Resetting the GPU doesn't affect the RPS/RC6 state, so we can stop forcibly reloading the registers. Ville suggested this many moons ago, I said at that time that sanitizing was no harm and meant that our bookkeeping was kept consistent with the HW. However, in a forthcoming series, we want to split rps/rc6 GT powermanagement and one of the key simplifications is the control of when we enable it. Performing a crude sanitize in the middle of i915_gem_reset() is then a huge wart.

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.
