The upcoming drm/xe driver [1][2] will reuse the drm/i915 display code, initially by compiling the relevant compilation units separately as part of the xe driver. This series prepares for that in i915 side. The first patch defines I915 during the i915 driver build, to allow conditional compilation based on the driver the code is being built for. The rest of the patches add stubs for functions in files that aren't used in xe. The idea is that this is the least intrusive way of skipping that code in xe, and is quite similar to the common kconfig stubs. While this is arguably unused code for the time being, or only used in an out-of-tree driver yet to be upstreamed, the upstreaming has to start somewhere. BR, Jani.
