I took 3.14-rt out for a quick spin on my 64 core box, it didn't work at all with 60 cores isolated. I didn't have time to rummage, but it looks like there are still bugs to squash. Biggest problem with CONFIG_NO_HZ_FULL is the price tag. It just raped fast mover performance last time I measured. -Mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
