Refactor i915_coherent_map_type to be GT-centric rather than
device-centric.  Each GT may require different coherency
handling due to hardware workarounds.

Semi-random place to comment, but it highlights well how IMO the API change to i915_coherent_map_type is a bit questionable.

This is not a shared mapping so workaround should not apply. There is no GT here at all so it is just a charade (passed in artificially to satisfy the API change) and so wrong.

Another instance of where mapping looks to be not shared seems to be the gsc_fw_load_prepare hunk, although I am not entirely sure about the lifecycle there. Presumably we populate the fw image on the CPU and then never touch it again at runtime but maybe that's not true, don't know.

Basically all GuC/HuC/PCP ones I am also not sure if they shared mappings or not.

The other ones seem okay to me - I mean truly objects which can be accesses by CPU and GPU simultaneously.

So question is can we do better in terms of API clarity and runtime scope? For instance should we leave i915_coherent_map_type as is and just have this smarter logic in a new intel_gt_coherent_map_type?

Downside is two APIs, which can add confusion too. Upside shmem_create_from_object is not misleading and can use a more efficient access. Maybe some other call sites too. How much efficient access matters.. probably not a lot. So I am thinking mostly from the point of view of being truthful to what is the issue.

Or even helpers should have explicit "shared" in the name?

Anyway, I think it is at least worth a short discussion.

Tvrtko
