fiasco/build/globalconfig.out

# CONFIG_AMD64_K8 is not set
# CONFIG_AMD64_CORE2 is not set
CONFIG_AMD64_CORE_I=y

l4/build/.config

CONFIG_BUILD_ARCH="amd64"
CONFIG_BUILD_ARCH_amd64=y
CONFIG_CPU="K8"
CONFIG_CPU_X86_K8=y


does it mean this mismatch? but when I rebuilt fiasco with

CONFIG_AMD64_K8=y
# CONFIG_AMD64_CORE2 is not set
# CONFIG_AMD64_CORE_I is not set

the same story so I need to go deeper into fiasco/kern/buddy_alloc.cpp
