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) |

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

KernelVersion: v3.15.0 |
|
Contact: |
|
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. |
