GPL-Browser
Daily updated index of all Kconfig findings of this variable on the GPL-Browser. Last update: 2024-11-15 05:09 GMT.
The Browse column points to the Path of the Kconfig containing this variable 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 this option does not mean it fits the respective model and architecture. See the Model-Matrix where it's used.
Dependencies
Daily updated index of all dependencies of this Kconfig-Variable. Last update: 2024-11-15 05:10 GMT.
The Dirs column lists the amount of root directories on the GPL-Browser containing the respective Relation.
The Firmware column lists the range of firmware versions covered by these directories.
The presence of a Relation does not mean it is used by AVM. See the Model-Matrix of each Object where it's used.

Model-Matrix
Daily updated index of the presence and value of this variable for each model. Last update: 2024-11-15 05:18 GMT.
Showing all models using this variable. 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 is merged from Firmware-Probes of all known AVM firmware for a model, including Recovery.exe and Labor-Files.
If the 'Value' column contains '<comp>' the variable is computed at runtime. '<empty>' means the variable is present but empty (rare).
Multiple values typically show a conditional static assignment or different values in different firmware.
