[okl4-developer] iguana scheduling security question

Hi Ben,

the next release of OKL4

Cool!!, are you planning to remove L4 scheduler from ukernel, or will
iguana, have an independent scheduler, that works with the help of L4
scheduler?,

I have come to some thinkings about user mode scheduling,  like for instance
timer_interrupt could be taken out of u-kernel to one mandatory thread
created by the root server, which will then tell the kernel about ticks with
a privileged syscall, in such a way it could use timer drivers on user
space. Anyways, lately i've been trying to make this multi-personality
scheduling server on top of iguana which is close to be "useful", if you can
call that useful :), anyhow, it has led me into some conclusions and/or
ideas about L4 scheduling, I'll post them sometime soon, when I get to
orginize such ideas:)

Sure,

Jorge
