There are two downsides to all kmods: - they increase build times when you're switching kernels - you sometimes find odd dependency issues in upstream which you don't want to fix This change makes the minimal (-m) build config not use ENABLE_ALL_KMODS. i.e. the defaults are the same, but using '-m' the build time is significantly decreased. We also amend the config application code so that it's possible to override (almost) anything in target_diffconfig. Approved-by: Sophronia Koilpillai Approved-by: Evan Benn

This MorseMicro script provides help automating the initialization of OpenWRT build.
|
|
Make sure you run this script from the top directory of OpenWRT!
|
|
|
|
Usage:
|
|
${0} <options>
|
|
options:
|
|
-i initializes openwrt by updating/installing feeds
|
|
|
|
-b <board> assembles config based on diffconfigs in target board folder.
|
|
|
|
-m minimal diffconfig. Includes only target_diffconfig when selecting
|
|
files from the board config. Often combined with '-x'
|
|
for custom configurations.
|
|
|
|
-x apply extra diffconfig options in common_extra. One of these is
|
|
'dev' (no minification, use local git-src if linked, etc.).
|
|
|
|
-g Override the source of a package to use a git-src tree.
|
|
Format is <PKG_NAME>:<git path>. (-g morse_driver:../morse_driver/)
|
|
Can be specified multiple times.
|
|
|
|
-l <target> loads selected target defconfig [deprecated]
|
|
|
|
-s <target> saves your current menuconfig from .config to a defconfig.
|
|
(this option overwrites pre-existing files!) [deprecated]
|
|
|
|
-e <toolchain_path> use the toolchain specified at <toolchain_path>
|
|
|
|
-E identifies the architecture of the selected board, and
|
|
downloads a toolchain from the configured VERSION_REPO.
|
|
By default, the toolchain will be extracted to /opt
|
|
unless -e specifies an alternative toolchain path.
|
|
|
|
eg.:
|
|
${0} -i -b ekh03v3
|
|
${0} -m -x dev -b ekh01
|
|
|
|
