|
|
+ help
|

+ This option enables the system-wide support for task boosting.
|
|
+ When this support is enabled a new sysctl interface is exposed to

+ /proc/sys/kernel/sched_cfs_boost
|
|
+ which allows to set a system-wide boost value in range [0..100].
|
|
+
|
|
+ The currently boosting strategy is implemented in such a way that:
|
|
+ - a 0% boost value requires to operate in "standard" mode by
|
|
+ scheduling all tasks at the minimum capacities required by their
|
|
+ workload demand
|
|
+ - a 100% boost value requires to push at maximum the task

+ performances, "regardless" of the incurred energy consumption
|

|
|
+ A boost value in between these two boundaries is used to bias the
|
|
+ power/performance trade-off, the higher the boost value the more the
|
|
+ scheduler is biased toward performance boosting instead of energy
|
|
+ efficiency.
|
|
+
|
