Apparatuses, methods, and computer-readable media are provided for operating a port manager to detect a first link condition or a second link condition of a circuitry. Under the first link condition, a first link between a downstream port of the circuitry and an upstream port of a switch is compatible to a first protocol, and a second link between a downstream port of the switch and an upstream port of a device is compatible to the second protocol. Under the second link condition, the first link exists and is compatible to the first protocol, while there is no second link being compatible to the second protocol. The port manager is to operate the downstream port of the circuitry according to the second protocol on detection of the first link condition, or according to the first protocol on detection of the second link condition. Other embodiments may be described and/or claimed.

A cache system may maintain size and/or request rate metrics for objects in a lower level cache and for objects in a higher level cache. When an L1 cache does not have an object, it requests the object from an L2 cache and sends to the L2 cache aggregate size and request rate metrics for objects in the L1 cache. The L2 cache may obtain a size metric and a request rate metric for the requested object and then determine, based on the aggregate size and request rate metrics for the objects in the L1 cache and the size metric and the request rate metric for the requested object in the L2 cache, an indication of whether or not the L1 cache should cache the requested object. The L2 cache provides the object and the indication to the L1 cache.
