List of never-enabled Kconfig symbols #19899

Closed ulfalizer closed 4 months ago

ulfalizer commented 4 years ago

Wrote a script that lists all symbols that are not user-configurable (have no prompt), have no defaults, and that aren't selected/implied. Such symbols can never be anything but n.

You could go through it and check if you see something that can be removed.

@ulfalizer note that BIG_ENDIAN is for off-tree architectures which are bigendian.

Thanks, removed that one.

Suspect there's other "false positives" in there too. This is unrelated to the all the unused symbol PRs btw.

PR #20316 depends on symbol SOC_GECKO_WDOG

erwango commented 4 years ago

@ulfalizer: USE_STDC_FOO and USE_STM32_BAR should be kept.

nashif commented 4 months ago

the info here is most likely outdated and with scripts available to update this 5 years later, only option is to close this and look back if there is an update.
