| Description: Writes are equivalent to writing to | |
| /sys/devices/system/cpu/cpuN/dscr on all CPUs. | |
| Reads return the last written value or 0. | |
| This value is not a global default: it is a way to set | |
| all per-CPU defaults at the same time. | |
| Values: 64 bit unsigned integer (bit field) | |

| Description: Default value for the Data Stream Control Register (DSCR) on | |
| a CPU. | |
| This default value is used when the kernel is executing and | |
| for any process that has not set the DSCR itself. | |
| If a process ever sets the DSCR (via direct access to the | |
| SPR) that value will be persisted for that process and used | |
| on any CPU where it executes (overriding the value described | |
| here). | |
| If set by a process it will be inherited by child processes. | |
| Values: 64 bit unsigned integer (bit field) |
