54 Types of errors
58 Codes that allow error correction when the number of errors on a bit packet
59 is below a threshold. If the number of errors is above, those mechanisms

69 corrected the error. Such errors are usually not fatal, although some
72 * **Uncorrected Error (UE)** - the amount of errors happened above the error
87 The mechanism for handling non-fatal errors is usually complex and may
173 The word with *data width* is sent to the CPU, even when errors happen.
180 The information about the CE/UE errors is stored on some special registers
183 bit CPUs, such errors can also be retrieved via the Machine Check
220 The ``edac`` kernel module's goal is to detect and report hardware errors
226 Memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the
227 primary errors being harvested. These types of errors are harvested by
259 In addition, PCI devices are scanned for PCI Bus Parity and SERR Errors
260 in order to determine if errors are occurring during data transfers.
262 The presence of PCI Parity errors must be examined with a grain of salt.
