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.
