I chose the variant based on SRC_URI, but used KERNEL_CONFIG_URI because I got
endless recursion between SRC_URI and KERNEL_FEATURES in the kernel recipe I
use.
I ended up with this function:
def insert_if_kernel_cache_available(feature, d):
import re
if d.getVar('KERNEL_CONFIG_URI'):
config_uri = d.getVar('KERNEL_CONFIG_URI')
kernel_cache = re.search("kernel-cache", config_uri)
if kernel_cache:
return feature
return ""
KERNEL_FEATURES:append = "${@insert_if_kernel_cache_available('
features/overlayfs/overlayfs.scc', d)}"
Many greetings,
Matthias
