Details

The remotewatchdog event is used for Inter-CPU communication of ar7wdt.ko instances on Puma6/7 models.

On Puma6 and Puma7 models FRITZ!OS is running on the ATOM CPU, while the cable modem frontend runs on the ARM CPU.
ar7wdt.ko is the management kernel module for AVM-Watchdogs, running on both Linux indtances on these models.
To connect both the ATOM side runs the avm_event_remotewatchdog source sending remotewatchdog events to the
avm_event_remotewatchdog_sink on the ARM side. The real watchdog which can reboot the system runs on the ARM side.

remotewatchdog events can register a watchdog and its timeout, release it, or perform the trigger to avoid a reboot.

// From include/uapi/avm/event/gen-types.h

struct _avm_event_remotewatchdog {
	struct _avm_event_header event_header;
	enum _avm_remote_wdt_cmd cmd;
	char name[16];
	unsigned int param;
};

enum _avm_remote_wdt_cmd {
	wdt_register = 0, /*--- RemoteCPU: param1: time to trigger ---*/ 
	wdt_release = 1, /*--- RemoteCPU ---*/ 
	wdt_trigger = 2, /*--- RemoteCPU: trigger ---*/ 
};

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.

Showing all models using this event. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
