How it works: 1. build/make/core/Makefile generates a txt file with the kernel version, which is taken from an explicit BOARD_KERNEL_VERSION value, or extracted from the kernel image on the source tree, or extracted from the kernel image extracted from the prebuilt boot.img. The file is saved at $ANDROID_PRODUCT_OUT/obj/PACKAGING/check_vintf_all_intermediates/kernel_version.txt. 2. If PRODUCT_ENABLE_UFFD_GC is "default", meaning the GC type needs to be determined by the kernel version, build/make/core/Makefile copies kernel_version.txt to out/soong/dexpreopt/kernel_version_for_uffd_gc.txt. 3. build/soong/dexpreopt/config.go writes the the UFFD GC flag to out/soong/dexpreopt/uffd_gc_flag.txt. The flag is determined by an explicit PRODUCT_ENABLE_UFFD_GC value or by contruct_uffd_gc_flag.py, which reads kernel_version_for_uffd_gc.txt and determines the flag accordingly. 4. dex2oat takes the UFFD GC flag from uffd_gc_flag.txt. 5. post_process_props.py mangles ro.dalvik.vm.enable_uffd_gc based on the same logic.
