On x86_64 with gcc version 13.3.0, I compile kernel with:
make defconfig
./scripts/kconfig/merge_config.sh .config <(
echo CONFIG_COMPILE_TEST=y
)
make KCFLAGS="-fno-inline-functions -fno-inline-small-functions -fno-inline-functions-called-once"
Then I get a linker error:
ld: vmlinux.o: in function `pxp_fw_dependencies_completed':
kintel_pxp.c:(.text+0x95728f): undefined reference to `intel_pxp_gsccs_is_ready_for_sessions'
This is caused by not having a intel_pxp_gsccs_is_ready_for_sessions()
header stub for CONFIG_DRM_I915_PXP=n. Add it.
