Thomas Zimmermann Sept. 15, 2020, 2:59 p.m. UTC
GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in exynos. The only exception is gem_prime_mmap,
which is non-trivial to convert.

Hm moving the drm_gem_cma_vm_ops into drm_gem.h or so and maybe calling
them drm_gem_simple_ops or so would remove a pile of these. But perhaps a
quick follow up series.

Good idea. Several interfaces use the term 'default' in their name, so
something like drm_gem_default_vm_ops seems appropriate.

BTW is there a reason why we have file operations like
DEFINE_DRM_GEM_CMA_FOPS() in each module? It seems like this could also
be provided by the rsp memory-manager library.

Best regards

Default sounds like a fine naming choice too.

It's for the module reference counting of the underlying file. So
file_operations need this.
