Power calibration previously stepped down 25 W at a time (linear), requiring up to 6 attempts to find a stable limit within 150 W range. New strategy: - Binary search between minLimitW (lo, assumed stable floor) and the starting/failed limit (hi, confirmed unstable), converging within a 10 W tolerance in ~4 attempts. - For thermal throttle: the first-quarter telemetry rows estimate the GPU's pre-throttle power draw. nextLimit = round5W(onset - 10 W) is used as the initial candidate instead of the binary midpoint, landing much closer to the true limit on the first step. - On success: lo is updated and a higher level is tried (binary search upward) until hi-lo ≤ tolerance, ensuring the highest stable limit is found rather than the first stable one. - Let targeted_power run to natural completion on throttle (no mid-run SIGKILL) so nv-hostengine releases its diagnostic slot cleanly before the next attempt.
