[Intel-gfx] [PATCH 17/21] drm/i915/gt: Track timeline GGTT offset separately from subpage offset

2020-12-10 Thread Chris Wilson
Currently we know that the timeline status page is at most a page in size, and so we can preserve the lower 12bits of the offset when relocating the status page in the GGTT. If we want to use a larger object, such as the context state, we may not necessarily use a position within the first page
