I don't know if there are builds available for SL, but there exists a Realtime kernel for RHEL6. On Red Hat certified hardware, it should provide a fairly comparable performance as the stock RHEL6 kernel, with max latency less than 150µs and std.dev less than 5µs. It's based upon the PREEMPT_RT patchset, but with a fairly newer kernel base than the stock RHEL6 kernel. <https://access.redhat.com/products/red-hat-enterprise-mrg-realtime/> If you can get hold of the SRPMS, it should be fairly easy to do a build, even using mock. -- kind regards, David Sommerseth
