<!--
Test configuration for assigning priorities
===========================================
On kernels that support priorities and where priority 128 is used as priority
limit (this is the case for OKL4 and Pistachio), this configuration should
result in the following assignments of physical priorities to process-tree
nodes:
128 : core
128 : core->init
128 : core->init->init.1
112 : core->init->init.1->init.11
96 : core->init->init.1->init.12
96 : core->init->init.1->init.12->init.121
64 : core->init->init.2
-->
<!--
prio_levels 2 divides priority range 1..128 into
65..128 (prio 0)
1..64 (prio -1)
-->
<config prio_levels="2">
