As a former heavy user of real time preempt patch and RTAI, I found
for many tasks I no longer needed it in the last few years. I'd
recommend putting in some fine grained auditing for time of
computations/io stages and measure the timing/jitter/stats as time
series to analyze system behavior. You might find it works perfectly
fine for you with the desktop kernel. Basically the timing jitter
we're talking here, assuming you've set your schedulers, split things
up appropriately, and tuned the slow/problematic spots, down to a
millisecond or under. I've had IO jitter, through use of tmpfs or
carefully written IO to XFS be very low jitter as well - but this is a
larger discussion (which the RT patch wont solve) if you have large
datarates (several hundred MiB/s).
I honestly don't think it's worth the effort to maintain it in a repo
with all the other kernels since the versions it works with are out of
sync with their stable release.

I am wondering what the status (if any) of the real time preempt patches are in openSUSE:Factory. I can't find any information on it for openSUSE at all.
I was hoping to use openSUSE for some scientific work that requires real time linux capabilities, and CONFIG_PREEMPT_RT is the version endorsed by upstream Linux. Are these patches being applied, or is there a kernel available that has them? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
