I found that this https://access.redhat.com/site/solutions/15482 answers a lot of questions on that behalf. It's about Readhat. Maybe something similar is available for Debian, too... -Michael ___ uClinux-dev mailing list uClinux-dev@uclinux.org

[uClinux-dev] Excluding one of n Cores

2013-07-29 Thread Michael Schnell
Hi Experts. Is there a kind of official way to set aside one of the available cores in an SMP system from the Linux OS to do deeply embedded extremely-low-latency stuff in a kind of single task main loop type environment ? I.e. creating a true coprocessor from an SMP hardware. Some of the
