The function is, presently, only called in __engines_record_defaults, as a part of
intel_gt_init. shmem_create_from_object uses i915_coherent_map_type to determine
the map_type to pass to i915_gem_object_pin_map_unlocked. This creates a pointer
that we pass to shmem_create_from_data. Aside from an i915_gem_object_is_shmem
check at the start, the function is otherwise just calling shmem_create_from_data...
which, itself, is only called by shmem_create_from_object.
I'd argue that any additional changes to shmem_create_from_object are unnecessary
as the function is only called from __engines_record_defaults. Additionally, the function
is a part of the gt library (shmem_utils.h is in the gt folder), so taking a gt argument should
be expected. However, if you still disagree, here's a few options for how we can rectify
this issue:
Debatably, we could just delete shmem_create_from_object and use the full expansion
in __engines_record_defaults. Though this may come with some additional complications,
such as the lost helper function being desirable in the future and needing to expand the
definition of shmem_create_from_data to include an object pinning requirement.
The second option is that we pass the map_type to the shmem_create_from_object function
instead of the GT, bypassing the need for i915_coherent_map_type in the function by breaking
it out as a part of __engines_record_defaults. I'll leave it to your judgement whether this would
be more or less confusing than just passing the GT.
Thirdly, we could just hard-code a specific map_type to use, though that seems ill-advised.
The last option is to rename the function to something more representative. Here's a few ideas
I can think of off the top of my head:
shmem_create
shmem_create_on_gt
shmem_create_from_gt
shmem_create_from_object_on_gt
intel_gt_create_shmem_from_object
If I had to recommend one approach over the rest, it would probably be the second option,
followed by the fourth.
