Could someone provide a link to the RT kernel that is used in SUSE, please? I've looked on OBS but can't find anything. I'd like to see what patches are applied etc, and also to see how it well it works on ARM.
Just curious, but why would you want a RT kernel at all, especially on a ARM system? Your overall throughput is usually slower, and unless you have a very specific hardware task, you don't need the latency guarantees that the -rt kernel provides, right?
Well, there are a couple of reasons. One is I need to see how the architecture behaves in comparison to others, like MIPS/Power/x86, in different circumstances; two and probably more crucially, we have customers looking at deploying Linux and have a hard requirement for RT.
Bad pun :) Seriously, do they really need RT? Or do they just think they do because they haven't measured what they really want to do and what Linux can provide "out of the box"? There are real reasons to use RT, but they are getting more and more rare and seem to dwarf the actual users of the RT patches that really don't need to do so.
