From df9871064e8b564d9ae2e56d561b64434fd004af Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sat, 26 Jul 2008 08:56:23 +1000 Subject: radeon: add initial atombios modesetting and GEM -> TTM translation layer. This is an initial import of the atom bios parser with modesetting support for r500 hw using atombios. It also includes a simple memory manager layer that translates a radeon GEM style interface onto TTM internally. So far this memory manager has only been used for pinned object allocation for the DDX to test modesetting. --- linux-core/drm_bo.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) (limited to 'linux-core/drm_bo.c') diff --git a/linux-core/drm_bo.c b/linux-core/drm_bo.c index 2e0d1243..0021530b 100644 --- a/linux-core/drm_bo.c +++ b/linux-core/drm_bo.c @@ -51,7 +51,6 @@ static void drm_bo_destroy_locked(struct drm_buffer_object *bo); static int drm_bo_setup_vm_locked(struct drm_buffer_object *bo); -static void drm_bo_takedown_vm_locked(struct drm_buffer_object *bo); static void drm_bo_unmap_virtual(struct drm_buffer_object *bo); static inline uint64_t drm_bo_type_flags(unsigned type) @@ -458,6 +457,7 @@ static void drm_bo_destroy_locked(struct drm_buffer_object *bo) DRM_ASSERT_LOCKED(&dev->struct_mutex); + DRM_DEBUG("freeing %p\n", bo); if (list_empty(&bo->lru) && bo->mem.mm_node == NULL && list_empty(&bo->pinned_lru) && bo->pinned_node == NULL && list_empty(&bo->ddestroy) && atomic_read(&bo->usage) == 0) { @@ -1838,8 +1838,8 @@ out_err_unlocked: EXPORT_SYMBOL(drm_buffer_object_create); -static int drm_bo_add_user_object(struct drm_file *file_priv, - struct drm_buffer_object *bo, int shareable) +int drm_bo_add_user_object(struct drm_file *file_priv, + struct drm_buffer_object *bo, int shareable) { struct drm_device *dev = file_priv->minor->dev; int ret; @@ -1858,6 +1858,7 @@ out: mutex_unlock(&dev->struct_mutex); return ret; } +EXPORT_SYMBOL(drm_bo_add_user_object); int drm_bo_create_ioctl(struct drm_device *dev, void *data, struct drm_file *file_priv) { @@ -2705,7 +2706,7 @@ void drm_bo_unmap_virtual(struct drm_buffer_object *bo) * Remove any associated vm mapping on the drm device node that * would have been created for a drm_bo_type_device buffer */ -static void drm_bo_takedown_vm_locked(struct drm_buffer_object *bo) +void drm_bo_takedown_vm_locked(struct drm_buffer_object *bo) { struct drm_map_list *list; drm_local_map_t *map; @@ -2734,6 +2735,7 @@ static void drm_bo_takedown_vm_locked(struct drm_buffer_object *bo) list->user_token = 0ULL; drm_bo_usage_deref_locked(&bo); } +EXPORT_SYMBOL(drm_bo_takedown_vm_locked); /** * drm_bo_setup_vm_locked: -- cgit v1.2.3
