# Makefile for top level of zCore

# Possible things to $(MAKE):
#
# rootfs-x64 : contains alpine-rootfs for x86_64, and compiled binary of linux-syscall/test/*.c
# riscv-rootfs : prebuilt binary for riscv64, contains busybox, libc-test and oscomp
# aarch64-rootfs: prebuilt binary for aarch64
# libc-test : build binary of libc-test for x86_64
# rcore-fs-fuse : install a tool called rcore-fs-fuse
# image : make a normal x86_64 image from alpine-rootfs
# riscv-image : make a riscv64 image from riscv-rootfs for testing
# aarch64-image: make a aarch6464 image from aarch64-rootfs for testing
# clean : delete all files generated by compilation
# doc : cargo doc --open
# baremetal-test-img : make a x86_64 image for testing
