Abstract: Examples described herein relate to a device indicating a number of available interrupt messages that is more than physical resources available to store the available interrupt messages and allocating one or more physical resources to provide one or more interrupt messages based on allocation of the one or more interrupt messages to a destination entity. The destination entity can request a maximum permitted allocation of interrupt messages regardless of interrupt message use level. The destination entity can request a maximum permitted allocation of interrupt messages regardless of interrupt message use level and allocate the requested maximum permitted allocation of interrupt messages for use in a configuration region of a device. However, based on unavailability of a physical resource to store a first interrupt message, allocation of the first interrupt message to a destination entity may not be permitted.
