What exactly should a microkernel have

Post by amd64pager »

I plan to build a microkernel,but what exactly does a microkernel contain?What basic services does it have to provide?
It's surprising what the semiconductor industry's definition of macro is and what the CS description is.

Microkernel
Every good solution is obvious once you've found it.

Thanks.Finishing the physical memory allocator.

Microkernel must have a fast file manager a strong and a powerful memory manager,good networking,faster process sheculding and more.

Monolithic kernels are better.
Linux,WindowsNT all are Monolithic Kernels.

I don't think fast or strong are mandatory for things you'd call a kernel, and it's quite subjective. Networking is also not a must, although it's worth supporting.

I am comparing the diferences between a mono and a micro.
I ment the few subjects in micro must be faster and stronger than a mono

WRONG.
Microkernel does NOT have file manager, memory manager, networking etc. See Minix source for one: http://www.minix3.org/
And monolithic kerners are NOT better. It depends on point of view, for example in stability and security monolithic kernels do not have a chance.
WindowsNT is NOT a monolithic kernel. http://en.wikipedia.org/wiki/Architecture_of_Windows_NT

Please do not spread false and unchecked information. Thanks.
