It typically takes about 10-15 minutes to do a complete active regen. But that really depends on the soot levels. It's not manditory to stay driving till it completes. When you restart the truck it will just run normal until it hits the soot% threshold again that triggers another regen.
Your truck starts and stops passive regens any time your egts exceed 572°. So they are off and on again depending on how you drive and what work you are asking the truck to do.
If you have guage display like the EDGE CTS you can see when the active regen starts and ends. If you don't, about the only indication you get is your instant fuel mileage will jump up a little when the PCM stops sending extra fuel into the exhaust system.
If the system gets really dirty, it will post a message "Drive to Clean" This message is telling you NOT to shut down mid regen, because the system really needs to complete what it has started. In 76,000 miles I've seen this message once.
I really ignor my regen message, I don't pay much attention to it, I just let it do it's thing. If I'm pulling off the road into tall grass or some other fire hazard, I might look at my Edge CTS to see if I'm in an Active regen and wait a few minutes for it to cool off. Or if I do notice it start while I'm on the freeway, I may take the farther exit and give it a an extra mile or two of freeway driving to finish what it's doing. But for the most part I ignor it.
