 Posted: Wed Feb 23, 2005 10:26 pm Post subject: How does Coldplug work? |
 |
|
Hi,
I was using genkernel and emerged coldplug. Now I compiled my own Kernel and therefor deleted coldplug from my default runlevel.
Now I found out that one of my Networkcards aren't working anymore(which is no suprise, since I didn't compile in the support for that type of card.)
Just for the fun of it I added coldplug to the default runlevel again, and now the networkcards works again. How can that be? Does coldplug bring his own Modules or something?
Thanks,
Chris |

No one knows how coldplug works??
I still haven't found any satisfying answers.
Thanks,
Chris |

| Maybe when you compiled your own kernel you compiled some stuff as modules? |

So coldplug is needed to load modules?

That's exactly what coldplug does. It loads modules automatically so you don't have to specify which ones to load in a config file. Whether you've just compiled your own kernel doesn't matter -- what matters is whether or not you've compiled support for your hardware into the kernel or compiled it in as a module. If your network card only works with coldplug, then you've compiled it in as a module. |

It apparently also calls the network initialization scripts after loading the module (just as hotplug does). Very useful, although it did confuse me a bit initially.  |

Is it bad to use Coldplug? I mean does it slow the system down?
Thanks,
Chris |

| I don't know that coldplug slows down your system. I know coldplug is very aggressive in the way it loads modules which can sometimes cause problems. For some reason coldplug will never allow me to coldplug pci devices so I just build them into my kernel or autoload them. |

Then I guess I just stay with coldlpug untill I get problems. but for know I stop worrying about it.
Thanks,
