When you look at the benchmark there is no difference between ll and ll+pre-empt. ll alone takes you to the 1ms point. pre-empt takes you no further and to get much out of pre-emption requires you go and do all the hideously slow and complex priority inversion stuff. > exactly that reason.

We have to work around common hardware not designed for SMP - the 8390 isnt a broken chip in that sense, its just from a different era, and there are a lot of them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | |||||||||
