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
Commands which open the device in fw 7.39 are:
- ISDN: telefon, dtrace, mobiled, capiotcp_server
- DSL: dsl_monitor
- WLAN: wland
- ctlmgr: libcmapi.so
Calculation
Here caculation findings will be collected. The source also contains an excel file explaining the calculation.
Ethernet power consumption from the source of avm_cpmac.ko fw 7.29:
/******************************************************************************\ * Powermanagement * * * * To report reasonable values to the powermanagement module there has to be * * distinguished between products with different hardware capabilities. As an * * example and base for the chosen values, here is an overview of values for * * the 7320 with two Gigabit PHYs.

GPL-Browser
Daily updated index of all avm_power.ko code findings on the GPL-Browser. Last update: 2024-04-19 20:13 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.
