EDAC (Error Detection and Correction) is a set of Linux kernel modules that handle reporting of hardware-related errors. Currently these modules mainly handle detection of ECC memory errors for many x86 and x86-64 chipsets and PCI bus parity errors. The edac-utils project currently has three components: libedac, edac-util, and edac-ctl. The libedac library presents a standard API for reading EDAC error counts and other information from sysfs, and edac-util uses this API to generate standard reports from the commandline. The edac-ctl utility is a perl script which uses config files to load the appropriate EDAC driver for a given chipset and register motherboard DIMM labels if they are configured. An init script is also provided which uses edac-ctl to initialize EDAC at system startup.
