From 4133be39e216130a86382fb5cfbaf6851a6f7a45 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 3 Dec 2024 15:51:16 +0800 Subject: [PATCH] tools/power turbostat: Exit on unsupported Intel models Turbostat requires per-platform enabling for Intel CPU models due to platform-specific features. When running on unsupported Intel CPU models, turbostat currently operates with limited default features, which can lead to users unknowingly using an outdated version of the tool. Enhance turbostat to exit by default when run on unsupported Intel CPU models, with a clear message to users, informing them that their CPU model is not supported and advising them to update to the latest version of turbostat for full functionality.
