Re: [LAU] resubmitting questions from last week

Thanks to my neighbor a few hours north, Brent for the confirmation. Was not aware of any "quota" on questions and did not mean to monopolize anything, just trying to learn some things here. Apologies if error was made. Thanks to Brent's assist, am now aware that those are IRQ statements, but still uncertain where to plug those in. Guess will keep googling in search of answers.

I never did get an answer to some of those questions either, so I figured maybe I'd been asking too many. (I have been posting a lot of them lately.) I think the ones you've got at the top for kernel options should be safe. I'm going to try -- at least initially -- not adjusting any IRQ priorities though. It might work, considering I've got a fast machine, and from what I hear, there are even people getting away with ordinary non-RT kernels these days. Preempt RCU was supposed to be buggy for awhile, but tested now for two years... (Source: LKML) Somebody said NO_HZ was actually a good thing on a laptop being used for pro-audio, and I suppose if you can do well on a laptop you can do well anywhere... (Source: Some guy with a laptop.) And HZ_1000 is recommended almost everywhere. I don't know what the meaning of NO_HZ and HZ_1000 is together, but I guess it'd mean a jiffy rate of 1000Hz, but only when interrupts are needed? I'm just putting stuff together from lots of googling too...
