Synchronize patches/linux/\$TAG with changes from a kernel GIT tree.
|
|
|
|
Usage:
|
|
$0 -k kernel-dir -o old-version [-t kernel-tag] [-p patch-dir] [-d defconfig-dir]
|
|
|
|
Options:
|
|
-h This help text
|
|
-k kernel-dir Path to kernel tree
|
|
-o old-version Version to be replaced by new kernel version
|
|
-t kernel-tag Base tag from which to generate patches.
|
|
Default: "v" + \$BR2_LINUX_KERNEL_VERSION
|
|
-p patch-dir Path to kernel patches directory
|
|
Default: \$BR2_EXTERNAL_INFIX_PATH + "/patches/linux/\$kernel-tag"
|
|
-d defconfig-dir Path to defconfig
|
|
Default: \$BR2_EXTERNAL_INFIX_PATH + "/configs"
|
|
|
|
Example:
|
|
cd infix/output
|
|
ln -s ../local.mk # Set LINUX_OVERRIDE_SRCDIR to git tree, e.g., ~/src/linux
|
|
../utils/kernel-refresh.sh -k ~/src/linux -o 6.12.21 -t v6.12.21 \\
|
|
-p ~/src/x-misc/patches/linux/6.12.21
