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

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