1 | What: /sys/devices/system/cpu/dscr_default |
2 | Date: 13-May-2014 | |
3 | KernelVersion: v3.15.0 | |
4 | Contact: | |
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) | |

12 | What: /sys/devices/system/cpu/cpu[0-9]+/dscr | |

15 | Contact: | |
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) | |

27 | What: /sys/devices/system/cpu/cpuX/topology/physical_package_id | |
28 | Description: physical package id of cpuX. Typically corresponds to a physical | |
29 | socket number, but the actual value is architecture and platform | |
30 | dependent. | |

33 | What: /sys/devices/system/cpu/cpuX/topology/die_id | |
34 | Description: the CPU die ID of cpuX. Typically it is the hardware platform's | |
35 | identifier (rather than the kernel's). The actual value is | |
36 | architecture and platform dependent. | |
37 | Values: integer | |
38 | ||
39 | What: /sys/devices/system/cpu/cpuX/topology/core_id | |
40 | Description: the CPU core ID of cpuX. Typically it is the hardware platform's | |
41 | identifier (rather than the kernel's). The actual value is | |
42 | architecture and platform dependent. | |
43 | Values: integer | |

51 | What: /sys/devices/system/cpu/cpuX/topology/book_id |
52 | Description: the book ID of cpuX. Typically it is the hardware platform's | |
53 | identifier (rather than the kernel's). The actual value is | |
54 | architecture and platform dependent. it's only used on s390. | |
55 | Values: integer | |
