How to set & use vtimer in OKL4 3.0 ?

[YBms]

Hello~! all~!

I want to build two oklinux in OKL4 3.0.

when i'm working.
there's some problem happens at ASSIGN IRQ.(maybe timer irq conflict problem.)

so i want to use vtimer as vtimer1, vtimer2

but, i don't know about how to set vtimer (before build kernel)
Please tell me about set & use vtimer in OKL4 3.0

Have a nice day~!
thank you~!
