Hi guys!
I am using simpleTimingCPU. And I am so confusing on how event affect
curTick? I see there is a “setCurTick()” after calling "serviceOne() “ in
“serviceEvents”. Is this denotes that curTick will be change by event?
I tried to add a “delayEvent” in addToWriteQueue in dram_ctrl.cc before
call nextReqEvent. This code likes
”
//before delay
if(pkt->isWrite()){
if (!delayEvent.scheduled())
schedule(delayEvent, curTick()+1);
}
//after delay
if (!nextReqEvent.scheduled()) {
DPRINTF(DRAM, "Request scheduled immediately\n");
schedule(nextReqEvent, curTick());
}
”
In my understand, I though this will make every events in the eventqueue that
after “delayEvent” will be delayed 1，because curTIck + 1. And finally make gem5
delay 1. But the result shows that there is no affect to those event that after
delayEvent.
I want to ask
1. Is Event insert into eventq on code sequence (which means delayEvent in
front of nextReqEvent in eventq) or on chronological order(which means
nextReqEvent in front of delayEvent in eventq) ?
2. Are there any method to make event after “delayEvent" delay a specified time
?
