Using 'make' directly means that the jobserver environment variables don't get passed down, so sub-builds for example don't use -j. This is documented as the wrong thing to do: https://www.gnu.org/software/make/manual/html_node/MAKE-Variable.html#MAKE-Variable Use $(MAKE) instead, and compile times drastically improve: acrn-devicemodel do_compile -13.5s -89.6% 15.0s -> 1.6s Tracked-On: #2370 Signed-off-by: Ross Burton <ross.burton@intel.com>
ACRN tools ########## The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the “ACRN Device Model”. This folder holds the source to a number of tools that facilitate the management, debugging, profiling, and logging of multi-OS systems based on ACRN. You can find out more about Project ACRN and its set of tools on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`Project ACRN documentation`: https://projectacrn.github.io/
