Systemd Services 101

Check that your system supports systemd

pidof systemd
2733

If this return a number then your system supports systemd. Most Linux distributions in 2017 support systemd.

Check out the proceses currently running.

Since systemd starts the process then all processes will be children of systemd

Simple example showing how to use DRM to : allocate a Dumb buffer on the GPU, use it as a framebuffer, use this CRTC on the currently connected screen (expecting 1 connected screen), export the buffer, reimport it implicitly with mmap and write in it.
// This will works on Embedded GPU that implements .gem_prime_mmap like Rockchip ones.
// This will fail on most DRM drivers for GPU with dedicated memory as they tend to NOT implement .gem_prime_mmap.
