I think you would also have to pass in the cpu_caching mode, and maybe
even the coh_mode, if we wanted that. Currently blt_create_object()
gives you a combination of cpu_caching, coh_mode and pat_index that is
the default and should "just work" for most cases. Idea is if you need
something more exotic you would instead create your own object (using
say gem_create_caching) and then also select whatever pat_index you needed.
I can change it to expose everything but figured blt_create_object()
should be more "I don't care, just give me the defaults".
