|
|
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.
