The wopcm registers are write-once, so any write after the first one will just be ignored. The registers survive a GPU reset but not always a suspend/resume cycle, so to keep things simple keep the writes in the intel_uc_init_hw function instead of moving it earlier to make sure we attempt them every time we try to load GuC.

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.
