This just says that for the kernel you are talking about (Linux?) it
changes the constants by calculating them in relation to the tick
frequency. OR maybe not, who knows? But since I am talking about Solaris
and I am trying to verify those recalculations, I am afraid that your
comment isn't helpful to me.
So the question still stands. What needs to change in the microkernel
code to accommodate different tick frequencies? Is it those things that
are calculated in relation to the HZ define in the microkernel reference
