Introduces a multi-dimensional TPU power model for Wattson, integrating frequency, cluster, and parallel request concurrency. Key changes: - Created a non-linear TPU power curve LUT with support for workload-based scaling. - Implemented TPU frequency and cluster extraction from 'DVFS' tracks. - Clamped request lookups to 8 for now due to measurement limitations. Bug: 454625451 Test: Wattson power estimation vs ground truth Signed-off-by: Runping Lai <runpinglai@google.com>

Yes. I have all the codes in hand but plan to send stdlib patch 1st, then UI patch 2nd, then metrics patch finally. Does that sound good? |
