Our sanitychecks indicate that while this register is context saved/restore, the HW does not preserve this bit within the register -- it likely doesn't exist, or one of those mythical bits that the architects insist does something despite all appearances to the contrary. For reference, SAMPLER_MODE is already in i915_reg.h as GEN10_SAMPLER_MODE and is being setup in icl_ctx_workarounds_init() as opposed to the chosen location here of rcs_engine_wa_init).

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
