It’s unused, you can go ahead and kill it.
Kernel: dies
It’s proportion integral derivative control of some functionality. Fans can use it.
only fans? 😆
There is no PID 0. I guess I’ll read the article.
Edit: This guy knows things
The tl;dr from the article (which is actually worth a read):
The very short version: Unix PIDs do start at 0! PID 0 just isn’t shown to userspace through traditional APIs. PID 0 starts the kernel, then retires to a quiet life of helping a bit with process scheduling and power management. Also the entire web is mostly wrong about PID 0, because of one sentence on Wikipedia from 16 years ago.
ITT: people giving wrong answers to a post linked to a blog that answers the question ‘What is PID 0?’
Nonsense, yes. Isn’t that what low effort posts (like nothing else but a link) are made for?
You can call it low effort, but Lemmy is a “link aggregator”. Even just sharing links has its value.
Wrong kind of link 😜
For me it just gives an error
post0 failed to load
.Edit: that’s probably my lemmy client trying to approach this blog as though it were a lemmy instance 🤦♂️
Mr. Anderson, Thank you for your analysis/work and well written treatise, on PID 0. I enjoyed learning more about Linux & Unix and a bit of history thereof as well.
I read that in Agent Smith’s voice.
The last time my community found a PID.0 in our midst, he was beaten downtown in broad daylight by over a dozen assailants, no witnesses.
