dc.description.abstractMemory-mapped I/O (MMIO) tracing provides an effective means for analyzing and debugging I/O related functions since it allows us to observe and track the interplay between processors and I/O devices [1]. However, existing MMIO tracing techniques have a serious drawback in multicore systems. Current MMIO techniques commonly use a memory protection mechanism to detect access to an MMIO address area under consideration. Unfortunately, this approach may miss some I/O events and even lead to a data race condition due to inappropriate management of concurrent accesses to the MMIO address area. In this paper, we describe a novel MMIO tracing approach introducing the notion of shadow page table. We use a shadow page table to allow only one processor to have access to a MMIO address area while forbidding other processors’ access to the same MMIO address area. We show how the shadow page table approach can be efficiently implemented on a multiprocessor platform with dual core ARM Cortex A15 CPU.en_US
