Yes, read pageWriteStamp. It is exactly build for SMC detection.

Setting a watchpoint would work if I was monitoring a known page, however thats not the case. I'm essentially trying to figure out when self modifying code writes to a page. I just wanted to see if Bochs was doing this already instead of adding a separate page dirty tracker.

It was there a while ago but now it isn’t.
Today you could set up write watchpoint with length of whole page and get a breakpoint exactly when write to the page happens.

What is the simplest way to find out if a page has been written to? Is there a flag somewhere that Bochs already sets when a page has been modified?
Thanks,
