Details

This module is part of the avm.ko module collection bundle.

checkpoint_proc.ko maintains a list of Inter-CPU checkpoints on Puma6 and Puma7 models.
Each checkpoint has a numerical ID and consists of a local and a remote node of type NODE_ATOM and NODE_ARM.
All nodes and checkpoints could be listed by a procfs interface at /proc/avm/checkpoints see the Examples below.

To synchronize the node list both instances of checkpoint_proc.ko register an avm_event_checkpoint_sink, and wait for
the remote avm_event_checkpoint_sink to appear. Once this happened an avm_event_checkpoint event source is created
to send a checkpoint event with the ID of the established checkpoint and the base address of the checkpoints array.

The question now is: Who uses this construct and for which purpose?

Examples

6490 fw 7.29 procfs on ATOM: 

root@fritz2:/var/mod/root# ls -l /proc/avm/checkpoints

-r--r--r--    1 root     root             0 May 10 13:24 /proc/avm/checkpoints
 
root@fritz2:/var/mod/root# cat /proc/avm/checkpoints

NODE_ATOM CHECKPOINT_08
NODE_ARM CHECKPOINT_08

6490 fw 7.29 procfs on ARM:

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.

GPL-Browser

Daily updated index of all checkpoint_proc.ko code findings on the GPL-Browser. Last update: 2024-04-27 04:15 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.
