Abstract
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.
