Android.mk

# This Android.mk is experimental. Please use with caution.
#
# The purpose of this file is to allow users to run 'mm' to
# rebuild the kernel from this tree. 'mm' is a faster command
# because it instructs the Android build system to not read
# every Android.mk file (and hence not check all dependencies).
# The benefit is that the user is able to essentially directly
# compile the kernel.
#
# Make sure to use the '-j' option when running 'mm' to spawn
# multiple jobs and speed up your build. For example:
# mm -j8
#
# You can also run 'mm' with a target that you would normally
# use when building the kernel. Just prefix "kernel-" in front.
#
# For example:
# mm kernel-mrproper is the equivalent of running make mrproper
