In one embodiment, a method includes: receiving, via a sideband interface of a multi-root agent associated with a first root space and a second root space, a reset prepare signal to inform the multi-root agent that the first root space is to be reset; sending, via the sideband interface, an acknowledgement signal to acknowledge the reset prepare signal; receiving one or more transactions for the first root space from a fabric coupled to the multi-root agent; and terminating the one or more transactions responsive to the reset prepare signal, where the first root space is in a reset state when the one or more transactions are received. Other embodiments are described and claimed.

In an embodiment, a processor includes at least one functional block and a central power controller. The at least one functional block may include at least one block component and block power logic. The block power logic may be to: receive a first request to initiate a first reduced power mode in the at least one functional block, and in response to the first request, send a notification signal to a central power controller. The central power controller may be to, in response to the notification signal: store a first state of the at least one functional block, and initiate the first reduced power mode in the at least one functional block. Other embodiments are described and claimed.

According to embodiments of the present invention, an adaptable traffic control system, method, article of manufacture, and apparatus receive a user-programmed value representing an amount of target traffic allowed through a connectivity device port and a user-programmed value representing a time interval during which to receive the allowed amount of target traffic. The two values define a percentage of target traffic allowed through the port for a particular port speed. One embodiment determines that port speed changed by a factor of N, scales the time interval by a factor of 1/N, and based on the allowed amount of target traffic and the scaled time interval, drops incoming target traffic when the received percentage of incoming target traffic is equal to (or greater than) the defined percentage of target traffic allowed through the port.
