Hi,
I am porting an application that requires very fine
timing control to Solaris 2.0/2.1. I need to be able to schedule
my program at given time increments. The time increment can be
anywhere from 1 millisecond to 50 milliseconds. I gave played
with setitimer and SIGALRM , they do work fine except I can not
get better than 10 millisecond granularity. So I decided
to try something more hardware oriented and noticed that there are
2 timer/counters in the MMU chip.
Questions:

1) Does the OS use either or both of these counters?
2) Are there other timers available on the Sparc platform?
3) Does the equation change if I use a VME based SparcEngine?
4) Does/Has anybody done/? any work in this area and give me some
   pointers?
5) Are there other calls in Solaris 2.0 and derivatives that would
   allow me to what I am trying to do ????

Thanx for any and all answers/pointers/criticism/etc...
