Hi,
Does anybody thought about kernel preemption for ARM boards? It could be usefull since kernel preemption is intended to embedded system or (Low-latency) Desktop.
Moreover, If we want to enable openGL on omap4 (pandaboard), we need a preemptible kernel.
Why?
Is there any objection to move to a preemptible kernel for omap2plus? For other ARM boards? For Factory and/or 12.2?
It usually incurs overhead for not too much perceivable gain. Have you run into latency issues?

I would love to see a PreemptRT kernel for openSUSE ARM, mostly as I am doing more PREEMPT_RT work, and it would also be useful for seeing how much of CGL we could comply with. For fear of adding _more_ kernels, could we not have RT kernels in addition to the regular ones - so have say a kernel-omap2plus and a kernel-rt-omap2plus etc? -- Andrew Wafaa IRC: FunkyPenguin GPG: 0x3A36312F -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
