# you can also set a specific kernel version, e.g. "6.0-rc4" or "5.10.51",
#  -> note however that a "z" too small on a "x.y.z" version may make patches fail
#     as they got adapted for newer "z" values.

# External config file to use - If the given file exists in path, it will override default config (customization.cfg) - Default is ~/.config/frogminer/linux-tkg.cfg
_EXT_CONFIG_PATH=~/.config/frogminer/linux-tkg.cfg

# Permanent root folder where to keep the git clone (linux-kernel.git subdir) and fetch new blobs
# Note: - Leave empty to use PKGBUILD's dir
#       - Start with a '/' for an absolute path in which `linux-tkg/linux-kernel.git/` will be created

#### KERNEL OPTIONS ####

# Name of the default config file to use for the kernel
# Default (empty)  : "config.x86_64" from the linux-tkg-config/5.y folder.
# "running-kernel" : Picks the .config file from the currently running kernel.
#                    It is recommended to be running an official kernel before running this script, to pick off a correct .config file
# "config_hardened.x86_64" : config file for a hardened kernel, available for kernel version "5.13", "5.10" and "5.4" .
#                            To get a complete hardened setup, you have to use "cfs" as _cpusched.
# User provided value : custom user provided file, the given path should be relative to the PKGBUILD file. This enables for example to use a user stripped down .config file.
#         If the .config file isn't up to date with the chosen kernel version, any extra CONFIG_XXXX is set to its default value.
# Note: the script copies the resulting .config file as "kernelconfig.new" next to the PKGBUILD as a convenience for an eventual re-use. It gets overwritten at each run.
#       One can use "kernelconfig.new" here to always use the latest edited .config file. modprobed-db needs to be used only once for its changes to be picked up.
_configfile=""

# Determine whether to call "olddefconfig" (default) or "oldconfig" for manual config updating interaction.

_llvm_ias=""

# Clang LTO mode, only available with the "llvm" compiler - options are "no", "full" or "thin".
# ! This is currently experimental and might result in an unbootable kernel - Not recommended !

# For BMQ:           0: No yield.
