Currently, it only detects one feature, i.e. hardware multithreading (such as Intel hyper-threading technology). The corresponding feature label is: feature.node.kubernetes.io/cpu-hardware_multithreading=true However, this (architecture/platform dependent) feature is not detected directly, and, the heuristics can be mislead. Detection works by checking the thread siblings of each logical (and online) cpu in the system. If any cpu has any thread siblings the feature label is set to true. Thus, hardware multithreading could be effectively disabled e.g. by putting all sibling cpus offline (even if the technology would be enabled in hardware). |
