gpu/drm/drm_gem_shmem_helper.c

30  * This library provides helpers for GEM objects backed by shmem buffers
33  * Functions that operate on the GEM object receive struct &drm_gem_shmem_object.
34  * For GEM callback helpers in struct &drm_gem_object functions, see likewise
119  * This function creates a shmem GEM object.
136  * @gemfs: tmpfs mount where the GEM object will be created
138  * This function creates a shmem GEM object in a given tmpfs mountpoint.
153  * drm_gem_shmem_free - Free resources associated with a shmem GEM object
154  * @shmem: shmem GEM object to free
156  * This function cleans up the GEM object state and frees the memory used to
223  * drm_gem_shmem_put_pages - Decrease use count on the backing pages for a shmem GEM object
224  * @shmem: shmem GEM object
275  * drm_gem_shmem_pin - Pin backing pages for a shmem GEM object
276  * @shmem: shmem GEM object
302  * drm_gem_shmem_unpin - Unpin backing pages for a shmem GEM object
303  * @shmem: shmem GEM object
321  * drm_gem_shmem_vmap - Create a virtual mapping for a shmem GEM object
322  * @shmem: shmem GEM object
323  * @map: Returns the kernel virtual address of the SHMEM GEM object's backing
327  * exists for the buffer backing the shmem GEM object. It hides the differences
391  * drm_gem_shmem_vunmap - Unmap a virtual mapping for a shmem GEM object
392  * @shmem: shmem GEM object
393  * @map: Kernel virtual address where the SHMEM GEM object was mapped
606  * drm_gem_shmem_mmap - Memory-map a shmem GEM object
607  * @shmem: shmem GEM object
610  * This function implements an augmented version of the GEM DRM file mmap
659  * @shmem: shmem GEM object
677  *                              pages for a shmem GEM object
678  * @shmem: shmem GEM object
738  *				 scatter/gather table for a shmem GEM object.
739  * @shmem: shmem GEM object
768  * drm_gem_shmem_prime_import_sg_table - Produce a shmem GEM object from
779  * A pointer to a newly created GEM object or an ERR_PTR-encoded negative
