gpu/drm/drm_gem_shmem_helper.c

31  * This library provides helpers for GEM objects backed by shmem buffers
34  * Functions that operate on the GEM object receive struct &drm_gem_shmem_object.
35  * For GEM callback helpers in struct &drm_gem_object functions, see likewise
119  * This function creates a shmem GEM object.
132  * drm_gem_shmem_free - Free resources associated with a shmem GEM object
133  * @shmem: shmem GEM object to free
135  * This function cleans up the GEM object state and frees the memory used to
202  * drm_gem_shmem_put_pages - Decrease use count on the backing pages for a shmem GEM object
203  * @shmem: shmem GEM object
250  * drm_gem_shmem_pin - Pin backing pages for a shmem GEM object
251  * @shmem: shmem GEM object
277  * drm_gem_shmem_unpin - Unpin backing pages for a shmem GEM object
278  * @shmem: shmem GEM object
296  * drm_gem_shmem_vmap - Create a virtual mapping for a shmem GEM object
297  * @shmem: shmem GEM object
298  * @map: Returns the kernel virtual address of the SHMEM GEM object's backing
302  * exists for the buffer backing the shmem GEM object. It hides the differences
366  * drm_gem_shmem_vunmap - Unmap a virtual mapping for a shmem GEM object
367  * @shmem: shmem GEM object
368  * @map: Kernel virtual address where the SHMEM GEM object was mapped
581  * drm_gem_shmem_mmap - Memory-map a shmem GEM object
582  * @shmem: shmem GEM object
585  * This function implements an augmented version of the GEM DRM file mmap
634  * @shmem: shmem GEM object
652  *                              pages for a shmem GEM object
653  * @shmem: shmem GEM object
713  *				 scatter/gather table for a shmem GEM object.
714  * @shmem: shmem GEM object
743  * drm_gem_shmem_prime_import_sg_table - Produce a shmem GEM object from
754  * A pointer to a newly created GEM object or an ERR_PTR-encoded negative
