Does this option provide the feature?
I have enabled this option in the latest L4Linux 3.9 and built with L4 r56,
but the name still not show in jdb for both x86 and ARM. If I remember
correctly, in previous L4Linux 3.7 and L4re-snapshot-2013012910, it does
the work.

For core placement, add

Is there any document about the parameter of the L4.Proto.Scheduler ?
What 0x18, 0x08 mean for Scheduler?
