Subject: [PATCH 23/32] CPU / PM: expose pm_qos_resume_latency for CPUs
|
|
|
|
[ commit 37efa4b41ffb31dcdfc3beb97d47992bb2a083e5 from linux-stable ]
|
|
|
|
The cpu-dma PM QoS constraint impacts all the cpus in the system. There is no way
|
|
to let the user to choose a PM QoS constraint per cpu.
|
|
|
|
The following patch exposes to the userspace a per cpu based sysfs file
|
|
in order to let the userspace to change the value of the PM QoS latency
|
|
constraint.
|
|
|
|
This change is inoperative in its form and the cpuidle governors have to
|
|
take into account the per cpu latency constraint in addition to the
|
|
global cpu-dma latency constraint in order to operate properly.
|
|
|
|
BTW
|
|
The pm_qos_resume_latency usage defined in
|
|
Documentation/ABI/testing/sysfs-devices-power
|
|
The /sys/devices/.../power/pm_qos_resume_latency_us attribute
|
|
contains the PM QoS resume latency limit for the given device,
|
|
which is the maximum allowed time it can take to resume the
|
|
device, after it has been suspended at run time, from a resume
|
|
request to the moment the device will be ready to process I/O,
|
|
in microseconds. If it is equal to 0, however, this means that
|
|
the PM QoS resume latency may be arbitrary.
