[PATCH OLK-6.6 0/3] Introduce CPU inspect feature
by Yu Liao 21 Dec '23

21 Dec '23

This patches series introduce CPU-inspect feature. CPU-inspect is designed to provide a framework for early detection of SDC by proactively executing CPU inspection test cases. Silent Data Corruption (SDC), sometimes referred to as Silent Data Error (SDE), is an industry-wide issue impacting not only long-protected memory, storage, and networking, but also computer CPUs. As with software issues, hardware-induced SDC can contribute to data loss and corruption. An SDC occurs when an impacted CPU inadvertently causes errors in the data it processes. For example, an impacted CPU might miscalculate data (i.e., 1+1=3). There may be no indication of these computational errors unless the software systematically checks for errors [1]. SDC issues have been around for many years, but as chips have become more advanced and compact in size, the transistors and lines have become so tiny that small electrical fluctuations can cause errors. Most of these errors are caused by defects during manufacturing and are screened out by the vendors; others are caught by hardware error detection or correction. However, some errors go undetected by hardware; therefore only detection software can protect against such errors [1].
