Slow probingSlow probingPosted Jul 27, 2006 15:30 UTC (Thu) by Max.Hyre (subscriber, #1054)Parent article: Kernel Summit 2006: Embedded systems
Much of the kernel's boot time is spent probing for devices....Could the kernel have a list of devices, prepared from a previous probe, which the kernel just takes as correct, to streamline that part? Obviously it would need to be updated for new or removed hardware, but if the list is wrong, on my head be it. Since this would lead to a spate of ``my system won't boot'' complaints, have it require a kernel argument, to restrict its use to those with something of a clue. I know I'd really appreciate it when I'm optimizing a kernel, and rebooting every few minutes.

Slow probing Posted Jul 27, 2006 17:30 UTC (Thu) by dlang (✭ supporter ✭, #313) [Link] this is exactly why I compile custom kernels for each machine, and only include drivers for hardware that exists (or has a high liklyhood of being added)
the one (partial) exception is my laptop, which is relativly slow anyway :-( but is mroe likly to have new hardware plugged into it in the form of pcmcia cards or strange USB devices.
