| DOC = ''' |
| This server side test suite tests for performance regressions where enabling |
| CPU idle hurts latency-sensitive workloads (e.g., smooth scrolling). |
| |
| This is done by running smoothness.top_25_smooth and comparing results for |
| idle enabled vs. disabled: ideally, there should be only a very small impact. |
| |
| This test currently only supports Arm aarch64. |
| |
| Pass local=True to run with local telemetry and no AFE server. |
