scheduler in linux

hi

i have a dought about linux scheduler.

in linux there are 3 policies of scheduling ie; round robin, FIFO and time sclice.

but if i want to have my own scheduling policy is it possible to insert such a scheduler in the linux kernel and use it instead of the default one.

You can get the source code for Linux, so the answer is yes.

but , in the linux documentation it is written linux kernel does not support loding of modules related to scheduling policies.

then when should these modules be loaded in the linux kernel. is it at boot time

You can't do it as a module. You can still write the thing, patch your kernel sources with it and recompile.

what are these kernel patches & how can a sheduler be patched with the kernel

You have to write them.

And seeing as you have no clue (as to what a kernel patch is), I wouldn't recommend it.
