Le 09/03/2021 à 01:02, Daniel Walker a écrit :

This is a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.

If you do that in a separate patch, you loose bisectability.

I think it would have been better to do things in a different way, more or less like I did in my series:
1/ Provide GENERIC cmdline at the same functionnality level as what is spread in the different architectures
2/ Convert architectures to the generic with least churn.
3/ Add new features to the generic

The bash script used to convert is as follows,

if [[ -z "$1" || -z "$2" ]]; then
echo "Two arguments are needed."
exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config

This is not correct.

By default, on powerpc the provided command line is used only if the bootloader doesn't provide one.

Otherwise:
- the builtin command line is appended to the one provided by the bootloader if CONFIG_CMDLINE_EXTEND is selected
- the builtin command line replaces to the one provided by the bootloader if CONFIG_CMDLINE_FORCE is selected

make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1
