Stefan Lankes
24914fcb4f
add prototype of a tickless kernel
...
only by entering the kernel, the tick counter will be updated
=> by using this feature, MetalSVM supports only LwIP's raw interface,
because we have no guarantee that the tcpip thread will get computation time
=> no NETCONN & BSD socket support
=> no load balancing support
