Macro Definition Documentation

DRM_GEM_VRAM_DRIVER

#define DRM_GEM_VRAM_DRIVER

Value:

    .debugfs_init    = drm_vram_mm_debugfs_init, \
    .dumb_create     = drm_gem_vram_driver_dumb_create, \
    .dumb_map_offset = drm_gem_ttm_dumb_map_offset

define DRM_GEM_VRAM_DRIVER - default callback functions for &struct drm_driver

Drivers that use VRAM MM and GEM VRAM can use this macro to initialize &struct drm_driver with default functions.

DRM_GEM_VRAM_PL_FLAG_SYSTEM

#define DRM_GEM_VRAM_PL_FLAG_SYSTEM   (1 << 0)

DRM_GEM_VRAM_PL_FLAG_TOPDOWN

#define DRM_GEM_VRAM_PL_FLAG_TOPDOWN   (1 << 2)

DRM_GEM_VRAM_PL_FLAG_VRAM

#define DRM_GEM_VRAM_PL_FLAG_VRAM   (1 << 1)

DRM_GEM_VRAM_PLANE_HELPER_FUNCS

#define DRM_GEM_VRAM_PLANE_HELPER_FUNCS

Value:

    .prepare_fb = drm_gem_vram_plane_helper_prepare_fb, \
    .cleanup_fb = drm_gem_vram_plane_helper_cleanup_fb

DRM_GEM_VRAM_PLANE_HELPER_FUNCS - Initializes struct drm_plane_helper_funcs for VRAM handling

Drivers may use GEM BOs as VRAM helpers for the framebuffer memory. This macro initializes struct drm_plane_helper_funcs to use the respective helper functions.
