+ Recent Opterons (Family 10h and later) provide for Memory Error
+ Injection into the ECC detection circuits. The amd64_edac module
+ allows the operator/user to inject Uncorrectable and Correctable
+ errors into DRAM.
+
+ When enabled, in each of the respective memory controller directories
+ (/sys/devices/system/edac/mc/mcX), there are 3 input files:
+
+ - inject_section (0..3, 16-byte section of 64-byte cacheline),
+ - inject_word (0..8, 16-bit word of 16-byte section),
+ - inject_ecc_vector (hex ecc vector: select bits of inject word)
+
+ In addition, there are two control files, inject_read and inject_write,
+ which trigger the DRAM ECC Read and Write respectively.
