Macro Definition Documentation

DRM_GEM_SHMEM_DRIVER_OPS

#define DRM_GEM_SHMEM_DRIVER_OPS

Value:

    .gem_prime_import       = drm_gem_shmem_prime_import_no_map, \
    .dumb_create            = drm_gem_shmem_dumb_create

DRM_GEM_SHMEM_DRIVER_OPS - Default shmem GEM operations

This macro provides a shortcut for setting the shmem GEM operations in the &drm_driver structure. Drivers that do not require an s/g table for imported buffers should use this.
