This has an explanation of the model up front, and then the detailed
formulae in Section 6.  This is from 2010, and there might have been
smaller changes since then, but I'm not aware of any bigger ones.

The cppmem tool is based on this, so if you want to play around with a
few code examples, it's pretty nice because it shows you all allowed
executions, including graphs like in the paper (see elsewhere in this
thread for CAS syntax):
