This function will be used later by the per (context,engine) power

No. This is not the appropriate uABI, please see
intel_engine_lookup_user().

uAPI wise, does this sound okay? :
#define I915_CONTEXT_PARAM_SSEU 0x7
__u64 value;
struct drm_i915_gem_context_param_sseu {
/*
* Engine to be configured or queried.
*/
__u32 class;
__u32 instance;
/*
* Setting slice_mask or subslice_mask to 0 will make the
context use
* masks reported respectively by I915_PARAM_SLICE_MASK or
* I915_PARAM_SUBSLICE_MASK.
*/
union {
struct {
__u8 slice_mask;
__u8 subslice_mask;
__u8 min_eus_per_subslice;
__u8 max_eus_per_subslice;
} packed;
__u64 value;
};
};
