Hi list,
I am playing with the examples in package cpu_reserve (i.e. res_rt_sched). However, for some reason the code doesn't work as expected.
In the worker-thread the function l4_rt_next_period() returns error nr 32 which is an IPC error, I guess its waiting for a msg from the reservation server here. Here is the sample output (qemu log):

Any ideas what I am doing wrong? Thanks in advance.
