On those three files, the ABI representation described at README are violated. - at sysfs-bus-iio-proximity-as3935: a ':' character is missing after "What" - at sysfs-class-devfreq: there's a typo at Description - at sysfs-class-cxl, it is using the ":" character at a file preamble, causing it to be misinterpreted as a tag. - On the other files, instead of "What", they use "Where".

What: /sys/class/devfreq/.../
|
|
Date: September 2011
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
Provide a place in sysfs for the devfreq objects.
|
|
This allows accessing various devfreq specific variables.
|
|
The name of devfreq object denoted as ... is same as the
|
|
name of device using devfreq.
|
|
|
|
What: /sys/class/devfreq/.../governor
|
|
Date: September 2011
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../governor show or set the name of the
|
|
governor used by the corresponding devfreq object.
|
|
|
|
What: /sys/class/devfreq/.../cur_freq
|
|
Date: September 2011
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../cur_freq shows the current
|
|
frequency of the corresponding devfreq object. Same as
|
|
target_freq when get_cur_freq() is not implemented by
|
|
devfreq driver.
|
|
|
|
What: /sys/class/devfreq/.../target_freq
|
|
Date: September 2012
|
|
Contact: Rajagopal Venkat <rajagopal.venkat@linaro.org>
|
|
Description:
|
|
The /sys/class/devfreq/.../target_freq shows the next governor
|
|
predicted target frequency of the corresponding devfreq object.
|
|
|
|
What: /sys/class/devfreq/.../polling_interval
|
|
Date: September 2011
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../polling_interval shows and sets
|
|
the requested polling interval of the corresponding devfreq
|
|
object. The values are represented in ms. If the value is
|
|
less than 1 jiffy, it is considered to be 0, which means
|
|
no polling. This value is meaningless if the governor is
|
|
not polling; thus. If the governor is not using
|
|
devfreq-provided central polling
|
|
(/sys/class/devfreq/.../central_polling is 0), this value
|
|
may be useless.
|
|
|
|
What: /sys/class/devfreq/.../trans_stat
|
|
Date: October 2012
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
This ABI shows the statistics of devfreq behavior on a
|
|
specific device. It shows the time spent in each state and
|
|
the number of transitions between states.
|
|
In order to activate this ABI, the devfreq target device
|
|
driver should provide the list of available frequencies
|
|
with its profile.
|
|
|
|
What: /sys/class/devfreq/.../userspace/set_freq
|
|
Date: September 2011
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../userspace/set_freq shows and
|
|
sets the requested frequency for the devfreq object if
|
|
userspace governor is in effect.
|
|
|
|
What: /sys/class/devfreq/.../available_frequencies
|
|
Date: October 2012
|
|
Contact: Nishanth Menon <nm@ti.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../available_frequencies shows
|
|
the available frequencies of the corresponding devfreq object.
|
|
This is a snapshot of available frequencies and not limited
|
|
by the min/max frequency restrictions.
|
|
|
|
What: /sys/class/devfreq/.../available_governors
|
|
Date: October 2012
|
|
Contact: Nishanth Menon <nm@ti.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../available_governors shows
|
|
currently available governors in the system.
|
|
|
|
What: /sys/class/devfreq/.../min_freq
|
|
Date: January 2013
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../min_freq shows and stores
|
|
the minimum frequency requested by users. It is 0 if
|
|
the user does not care. min_freq overrides the
|
|
frequency requested by governors.
|
|
|
|
What: /sys/class/devfreq/.../max_freq
|
|
Date: January 2013
|
|
Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
|
|
Description:
|
|
The /sys/class/devfreq/.../max_freq shows and stores
|
|
the maximum frequency requested by users. It is 0 if
|
|
the user does not care. max_freq overrides the
|
|
frequency requested by governors and min_freq.
|
|
The max_freq overrides min_freq because max_freq may be
|
|
used to throttle devices to avoid overheating.
