This feature will allow the scheduler to maintain a tunable window
|
|
based set of metrics for tasks and runqueues. These metrics can be
|
|
used to guide task placement as well as task frequency requirements
|
|
for cpufreq governors.

|
This module provides the means of debugging long preempt and
|
|
irq disable code. This helps in identifying the scheduling
|
|
latencies. The module rely on preemptirq trace hooks and
|
|
print the stacktrace to the ftrace upon long preempt and irq
|
|
events. Sysctl knobs are available for the user to configure
|
|
the thresholds.
|
|
|
|
This module also used to crash the system to catch issues
|
|
in scenarios like RT throttling and sleeping while in atomic
|
|
context etc.

help
|
|
This feature will allow the scheduler to disable low power
|
|
modes on a cpu if conservative boost is active. The cpu
|
|
will not enter low power mode for a hysteresis time period,
|
|
which can be configured from userspace.
