that related?[18:11:44] <LeftWing> Not directly.[18:12:27] <LeftWing> I had always understood a "tickless" kernel to mean, roughly, that the basic functioning of the system didn't depend on waking up and doing work on a high, fixed frequency[18:12:51] <LeftWing> e.g., right now we call "set_freemem()" in "clock()"[18:14:41] <LeftWing> And update various statistics, kick off periodic workers, etc[18:16:03] <LeftWing> Doing things like this often (e.g., at 1000hz in a system with "hires_tick" enabled) mean you can't put the CPU into deeper sleep states, and it increases the baseline CPU utilisation of a baseline virtualised guest.[18:16:40] <LeftWing> (At least, that's what I understand the theory to be)[18:16:51] *** freakazoid0223

cyclics are indeed of arbitrary resolution.[18:19:06] <LeftWing> It all depends on your goals, and I'm not sure exactly what the goals of the tickless project were -- or what goals somebody who might reprise it would have.[18:19:46] <jbk> ISTR one of the guys that was involved with it did send an email or two to illumos-discuss talking about the remaining bits a _long_ time ago[18:21:00]
