b2d6c81074 using the variable "environment" to determine the environment

a885c99cf2 only by setting DYNAMIC_TICKS, the tsc counter is used to realize round-robin 2016-09-22 18:31:03 +02:00
Stefan Lankes
fbaf77c8fd add counter to the task control block to determine the computation time 
- the counter represents the time at which the task is scheduled on the
  cpu
- if two or more tasks are running on the same cpu, we use this value to
  determine an expired time slice
=> task switching for round-robin scheduling
