| 33 * | |
| 34 * Correctable errors generally cause changes to the DIMM-related state (see | |
| 35 * cmd_dimm.c), whereas uncorrectable errors tend to use the bank-related | |
| 36 * routines (see cmd_bank.c). The primary exception to this division (though | |
| 37 * it eventually devolves to one of the two) is the RxE/FRx pair emitted by | |
| 38 * UltraSPARC-IIIi processors. With these errors, a complete pair must be | |
| 39 * received and matched before we know whether we're dealing with a CE or a UE. | |
