Hey Pavel > Wow, I did not know, thanks. I until on 319.xx I had wondered. lol. ~ because telling someone who is using nvidia-rt >325xx that it doesn't work on rt is a bit odd. ;) ... I thought you must have been mistaken :) take a look in kernel/conftest.sh (of nvidia installer/sources) - You were mistaken because nvidia has changed some of the internals around / how their installer works. It actually appears they are making it more RT friendly... Which is great because i (personally) have been bugging them every couple of months about PREEMPT_RT_FULL :) >>> 3.

Although, delay in 1000 nanoseconds - it's awful >> Would you care to goto into more detail on this? > > https://www.kernel.org/doc/Documentation/memory-barriers.txt Thanks, i'll have a read through + wait for some feedback from nvidia in my thread. 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
