Details

avm_power.ko is a (virtual) power management module by AVM.
It sends information about the CPU load and power consumption to the system.

It provides the /dev/avm_power device for Configuration of its power calculations.

This is a virtual module to have an article about it. It is part of the kernel source at: 

drivers/char/avm_power/

On Puma6 and Puma7 models avm_power.ko runs in dual Linux mode, see the explanation of the powermanagment_remote event.

Events

Daily updated index of AVM-Events and AVMIPC-Datastore nodes affecting this module. Last update: 2023-12-10 05:13 GMT.
The owners of Event-Sinks and Event-Sources are manual research, which may be incomplete or even wrong.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Configuration

Configurartion is done at boot time using the write only /dev/avm_power device. Excerpt from files fw 7.39: 

cat /lib/modules/pm_info.in >/dev/avm_power

Let's have a look at the config file: 

cat lib/modules/pm_info.in

PMINFO_MODE=7,100,141,10,100
PMINFO_MODE=4,100,130,10,100
PMINFO_MODE=1,100,0,1,0
PMINFO_MODE=14,100,29,10,-17
PMINFO_MODE=2,100,0,1,1500
PMINFO_MODE=3,100,0,1,2500
PMINFO_MODE=8,100,200,78,150
PMINFO_MODE=11,900,5,1,0
PMINFO_MODE=10,100,15,1,0
PMINFO_MODE=9,2267,1,1,50

Possible commands from the usage help debug output in avm_power_file.c: 

PMINFO_MODE = device, norm_rate, multiplier, divider, offset
PMINFO_SET  = device, power_rate
ETH_MODE    = port, state
LOAD_MODE   = mode (0 auto, 1 off, > 1 Level)
IDLE_MODE   = mode

The device also allows to set PowerMode scripts: 

echo MODE="name"  >/dev/avm_power

Here the list of scripts from power.h, not all of these work from userland: 

* te_active
* dsl
* LTE
* ata
* vdsl
* update
* dect_trace_on
* dect_trace_off
* telefon_profile_on
* telefon_profile_off
* multicast_profile_on
* multicast_profile_off
* voip_profile_on
* voip_profile_off
* usb_current_req
* pcmlink_bus_off
* pcmlink_bus_on
* pots_load
* te_load
* te_reload
* pots_reload
* tepots_switchauto
* tepots_switchmanu
* lock_governor
* unlock_governor
* e1_active
* e1_inactive

Calculation

Here caculation findings will be collected. The source also contains an excel file explaining the calculation.

GPL-Browser

Daily updated index of all avm_power.ko code findings on the GPL-Browser. Last update: 2024-11-15 05:07 GMT.
The Files header attempts to list the files which belong to this module. Useful if a directory contains multiple modules.
The Browse column points to the Path of the Makefile referring this code on the gpl.boxmatrix.info service.
The SoC column lists the Chip-Codenames, the Model column lists the nicks of the Box-Models.
The Diff column links the comparison of the AVM Kernel to the pristine original from Kernel.org.
The Download column links the full tarball the respective directory content is extracted from.
The presence of the source does not mean it fits the respective model and architecture. See the Model-Matrix where it's used.
Note that this list matches module names with hyphen (-) and underscore (_) exchangeable, same as modprobe does.
