Abstract: A real request from a CPU to the same memory bank as a prior prefetch request is transmitted to the per-memory bank logic along with a kill signal to terminate the prefetch request. This avoids waiting for a prefetch request to complete before sending the real request to the same memory bank. The kill signal gates off any acknowledgement of completion of the prefetch request. This invention reduces the latency for completion of a high priority real request when a low priority speculative request to a different address in the same memory bank has already been dispatched.

Abstract: An improved technique for processing IO requests has been described that distinguishes bogus IOs from genuine IO request failures by accessing a hardware configuration record that associates available paths with hardware components at different hardware layers traversed by the paths. When an IO request fails down a first path, a second path is selected for retrying the IO request by accessing the hardware configuration record and identifying a path that the record indicates traverses hardware components that are different from those traversed by the first path at multiple hardware layers. The chance that an IO request will fail due to faulty hardware over both the first path and the second path is thus low, such that IO failures down both the first path and the second path provide a clear indication that the IO request is bogus.
