Storing the EU mask internally in the same format the I915_QUERY topology queries use makes the final copy_to_user() a bit simpler, but makes the rest of the driver's SSEU more complicated and harder to follow. Let's switch to an internal representation that's more natural: Xe_HP platforms will be a simple array of u16 masks, whereas pre-Xe_HP platforms will be a two-dimensional array, indexed by [slice][subslice]. We'll convert to the uapi format only when the query uapi is called. v2: - Drop has_common_ss_eumask. We waste some space repeating identical EU masks for every single DSS, but the code is simpler without it. (Tvrtko) v3: - Mask down EUs passed to sseu_set_eus at the callsite rather than inside the function. (Tvrtko) - Eliminate sseu->eu_stride and calculate it when needed.
