CR3 might work. Does the kernel change it on every context switch (user program)? The main reason for having it is when tracing user code the kernel can context switch on you. If you want to see all the code that was executed in a process and compare it to what it should have executed you need some kind of identifier to disambiguate processess. The ASID is an easy way to do this, while rooting around in the Linux process structure is annoying. > On 2011-05-04 21:08:25, Gabe Black wrote: > > src/cpu/SConscript, line 188 > > <http://reviews.m5sim.org/r/678/diff/1/?file=12418#file12418line188> > > > > This isn't from your change, but should this be missing ExecSymbol?
