#     powernv/npu: Add a debugfs setting to change ATSD threshold
#     
#     The threshold at which it becomes more efficient to coalesce a range of
#     ATSDs into a single per-PID ATSD is currently not well understood due to a
#     lack of real-world work loads. This patch adds a debugfs parameter allowing
#     the threshold to be altered at runtime in order to aid future development
#     and refinement of the value.
