No. Those are I/O device accesses, not memory accesses. Look at the
softmmu code instead.
Like I said, I did add some debugging code to softmmu_template.h. The
read/writes I'm seeing are being generated by that softmmu debugging
code, not the iommu code. Sorry if I wasn't clear. Is there some other
softmmu code I should be looking at?
It may be easiest to add some new instrumentation in the translation
code for whatever target you're interested in.
I'm just focusing on Linux i386. I'm only beginning to explore the
qemu source, so any pointer to files/functions I should look at will
be much appreciated!
TIA,
Diwaker
