I have been digging around to find information on the tick and tick  
compare registers (%stick and %stick_cmpr), but I have found hardly  
any info (even the SPARCV9 manual doesn't list them!). Do you have any  
pointers on how the registers are used? As I'd mentioned before, I  
would like to make the timer interrupts less frequent so that I  
simulate a 2GHz-like balanced machine with the 75MHz simics system,  
for which I need to make timer interrupts far less frequent.
Thanks,
Pradeep.
