Subject: how can i figure out where a particular kernel config option came from?
Date: Wed, 9 Dec 2015 05:36:19 -0500 (EST) [thread overview]
Message-ID: <alpine.LFD.2.20.1512090532270.21086@localhost> (raw)
short version: with a short BSP layer i've been handed, the eventual
kernel .config file ends up with the setting:
CONFIG_WIRELESS=y
which makes no sense as the target board has no wireless and the BSP
itself doesn't set that, so how can i start tracking back to figure
out where that particular setting came from?
long version: i'm actually using Wind River Linux 7, but the
question remains the same. it turns out that CONFIG_WIRELESS is
selected by CONFIG_WLAN, so i'm really after what sets CONFIG_WLAN. i
don't see it in the BSP layer, so i'm tracing back to the WR kernel
recipe, and possibly features templates and any other kernel .cfg
snippets i can find, so far with no luck.
in either case, is there a log file that lists *precisely* which
kernel config snippets contributed to the final .config file? thanks.
