From c30b225dba01b4605262084592789e98a338c685 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 11 Sep 2019 13:09:09 +0200 Subject: drm/vram: Unexport internal functions of VRAM MM The init, cleanup and mmap functions of VRAM MM are only used internally. Remove them from the public interface. v2: * update for debugfs support Signed-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20190911110910.30698-4-tzimmermann@suse.de --- drivers/gpu/drm/drm_gem_vram_helper.c | 38 +++++------------------------------ 1 file changed, 5 insertions(+), 33 deletions(-) (limited to 'drivers/gpu/drm/drm_gem_vram_helper.c') diff --git a/drivers/gpu/drm/drm_gem_vram_helper.c b/drivers/gpu/drm/drm_gem_vram_helper.c index b5d342423bb2..31b037bc2d3f 100644 --- a/drivers/gpu/drm/drm_gem_vram_helper.c +++ b/drivers/gpu/drm/drm_gem_vram_helper.c @@ -889,19 +889,8 @@ int drm_vram_mm_debugfs_init(struct drm_minor *minor) } EXPORT_SYMBOL(drm_vram_mm_debugfs_init); -/** - * drm_vram_mm_init() - Initialize an instance of VRAM MM. - * @vmm: the VRAM MM instance to initialize - * @dev: the DRM device - * @vram_base: the base address of the video memory - * @vram_size: the size of the video memory in bytes - * - * Returns: - * 0 on success, or - * a negative error code otherwise. - */ -int drm_vram_mm_init(struct drm_vram_mm *vmm, struct drm_device *dev, - uint64_t vram_base, size_t vram_size) +static int drm_vram_mm_init(struct drm_vram_mm *vmm, struct drm_device *dev, + uint64_t vram_base, size_t vram_size) { int ret; @@ -921,34 +910,17 @@ int drm_vram_mm_init(struct drm_vram_mm *vmm, struct drm_device *dev, return 0; } -EXPORT_SYMBOL(drm_vram_mm_init); -/** - * drm_vram_mm_cleanup() - Cleans up an initialized instance of VRAM MM. - * @vmm: the VRAM MM instance to clean up - */ -void drm_vram_mm_cleanup(struct drm_vram_mm *vmm) +static void drm_vram_mm_cleanup(struct drm_vram_mm *vmm) { ttm_bo_device_release(&vmm->bdev); } -EXPORT_SYMBOL(drm_vram_mm_cleanup); -/** - * drm_vram_mm_mmap() - Helper for implementing &struct file_operations.mmap() - * @filp: the mapping's file structure - * @vma: the mapping's memory area - * @vmm: the VRAM MM instance - * - * Returns: - * 0 on success, or - * a negative error code otherwise. - */ -int drm_vram_mm_mmap(struct file *filp, struct vm_area_struct *vma, - struct drm_vram_mm *vmm) +static int drm_vram_mm_mmap(struct file *filp, struct vm_area_struct *vma, + struct drm_vram_mm *vmm) { return ttm_bo_mmap(filp, vma, &vmm->bdev); } -EXPORT_SYMBOL(drm_vram_mm_mmap); /* * Helpers for integration with struct drm_device -- cgit v1.2.3
