73 | Recent Opterons (Family 10h and later) provide for Memory Error | ||
74 | Injection into the ECC detection circuits. The amd64_edac module | ||
75 | allows the operator/user to inject Uncorrectable and Correctable | ||
76 | errors into DRAM. | ||
77 | |||
78 | When enabled, in each of the respective memory controller directories | ||
79 | (/sys/devices/system/edac/mc/mcX), there are 3 input files: | ||
80 | |||
81 | - inject_section (0..3, 16-byte section of 64-byte cacheline), | ||
82 | - inject_word (0..8, 16-bit word of 16-byte section), | ||
83 | - inject_ecc_vector (hex ecc vector: select bits of inject word) | ||
84 | |||
85 | In addition, there are two control files, inject_read and inject_write, | ||
86 | which trigger the DRAM ECC Read and Write respectively. | ||
