Abstract: Programmable hardware devices are re-programmed without system downtime. To reprogram the device, the device is quiesced, state associated with the device is saved, updates are loaded, the state is restored and operations are resumed, all transparent to the system, except for a possible delay in the system.

Abstract: Processing within a device is controlled in order to avoid a deadlock situation. A local request engine of the device determines prior to making a request whether the port of the device that is to service the request is making forward progress in processing other requests. If forward progress is being made, then the request is forwarded to the port. Otherwise, the request is held. This avoids a deadlock situation and allows the device to remain operative even in partial recovery situations.
