kernel application

hi

Is it possible to run an application in kernel space? without using the shell. particularly in linux
thanks

User-level code and kernel-level code have different expectations, so i doubt it'll work (e.g. your application is calling malloc() and the kernel only has kmalloc which doesn't work the exactly same way)

what you can do is using kernel modules.

just so you know, there is a project (i forget the name) which will execute any arbitrary user mode application in kernel mode on linux.

I read about it in linux journal and they demonstrated vmware in kernel mode and noticed a sizeable increase in performance due to far less switches in and out of kernel mode.

I guess that is more the exception then the rule (I mean the speed) ...
Compare khttpd (which is not in 2.6 anymore) and Apache 2, where I have heard they are basically equal.
