1) About having the mmio_table.h, I would like to keep the stuff in a
dedicated header as putting them in intel_gvt.h might needs i915 guys
to maintain it.
2) The other one is about if we should move the mmio_table.c into
i915 folder. I guess we need the some comments from Jani. In the
current version that I am testing, it's still in GVT folder. Guess we
can submit a patch to move it to i915 folder later if Jani is ok
about that.
Yes, let's have Jani chime in on these. They're basically one and the
same issue. This code will have to be built into into the core i915
driver even with my planned split, which is kindof the point of this
exercise. I think it makes sense to use the subdirectories as boundaries
for where the code ends up and not to declarare maintainership boundaries,
but it will be up to the i915 and gvt maintainers to decide that.
Agreed. If there's going to be a gvt.ko, I think all of gvt/ should be
part of that module, nothing more, nothing less.

The gvt related files in i915/ should probably be named intel_gvt* or
something, ditto for function naming, and we'll probably want patches
touching them be Cc'd to intel-gfx list.

Joonas, Rodrigo, Tvrtko, thoughts?

BR,
Jani.

Hi Christoph and Jani:

Thanks for the comments. It would be nice that people can achieve a agreement. I am OK with both of the options and also moving some files into different folders doesn't needs me to do the full test run again. :)


Thanks,

Zhi.
