What: /sys/devices/system/cpu/dscr_default Date: 13-May-2014 KernelVersion: v3.15.0 Contact: 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 Date: 13-May-2014 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. Values: 64 bit unsigned integer (bit field) |
