[PATCH v2 0/3] drm/shmem-helper: Cleanup public interface
The interface of GEM SHMEM helpers inconsistently uses either struct drm_gem_object or drm_gem_shmem_object for the GEM object. Convert GEM SHMEM functions to accept struct drm_gem_shmem_object, provide small wrappers for GEM object callbacks and update all users. Converting all GEM object functions to use drm_gem_shmem_object enables type checking by the C compiler. Previous callers could have passed any implementation of drm_gem_object to the GEM SHMEM helpers. It also removes upcasting in the GEM functions and simplifies the caller side. No functional changes. For GEM object callbacks, the SHMEM helper library now provides a number of small wrappers that do the necessary upcasting. Again no functional changes. v2: * documentation fixes and updates (Daniel) Thomas Zimmermann (3): drm/shmem-helper: Unexport drm_gem_shmem_create_with_handle() drm/shmem-helper: Export dedicated wrappers for GEM object functions drm/shmem-helper: Pass GEM shmem object in public interfaces drivers/gpu/drm/drm_gem_shmem_helper.c | 131 ++++++-------- drivers/gpu/drm/lima/lima_gem.c | 18 +- drivers/gpu/drm/lima/lima_sched.c | 4 +- drivers/gpu/drm/panfrost/panfrost_drv.c | 2 +- drivers/gpu/drm/panfrost/panfrost_gem.c | 20 ++- .../gpu/drm/panfrost/panfrost_gem_shrinker.c | 2 +- drivers/gpu/drm/panfrost/panfrost_mmu.c | 5 +- drivers/gpu/drm/panfrost/panfrost_perfcnt.c | 6 +- drivers/gpu/drm/v3d/v3d_bo.c | 22 +-- drivers/gpu/drm/virtio/virtgpu_object.c | 27 ++- include/drm/drm_gem_shmem_helper.h | 168 +++++++++++++++--- 11 files changed, 256 insertions(+), 149 deletions(-) base-commit: 215295e7b0a3deb2015c6d6b343b319e4f6d9a1d -- 2.33.1

[PATCH v2 3/3] drm/shmem-helper: Pass GEM shmem object in public interfaces
Change all GEM SHMEM object functions that receive a GEM object
of type struct drm_gem_object to expect an object of type
struct drm_gem_shmem_object instead.
This change reduces the number of upcasts from struct drm_gem_object
by moving them into callers. The C compiler can now verify that the
GEM SHMEM functions are called with the correct type.
For consistency, the patch also renames drm_gem_shmem_free_object to
drm_gem_shmem_free. It further updates documentation for a number of
functions.
v2:
* mention _object_ callbacks in docs (Daniel)
