> does it mean that -RT option is now in the kernel core ? not exactly. From what i have seen discussed on this list, Jack-dev list and through googling ~ 2.6.39 contains one of the main parts of the RT series. It's called something like "forced-interruupt-threading" in the kernel config (can't remember the exact phrase). So RT is almost upstream. but i think there are still a few patches/parts to migrate over. 2.6.39 is pretty good, i use RT mostly for music/recording applications - and am using 2.6.39 over 2.6.33-rt . Mind you, I can't even use .33 anymore, because it is too outdated and isn't very usable on my main desktop PC. It does look like RT will be totally mainline soonish, although 2.6.37 is supposed to have an RT kernel. I guess we will see what happens, but i for one will be happy when it's all upstream, so that i can always keep my kernel current, while still being able to use all of my RT-type apps effectively. jordan -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
