I thought so. But the only callers are in drm_agpsupport.c, which depends on CONFIG_AGP in the Makefile. So I expected this to work.

enabled. Did you check for that? I should all work if we have the dummy inlines for relevant agp functions in linux/agp_backend.h. -Daniel--- drivers/gpu/drm/drm_agpsupport.c | 12 ++++++------ drivers/gpu/drm/drm_memory.c | 18 ------------------ include/drm/drm_agpsupport.h | 18 ------------------ 3 files changed, 6 insertions(+), 42 deletions(-) diff --git a/drivers/gpu/drm/drm_agpsupport.c b/drivers/gpu/drm/drm_agpsupport.c index 4c7ad46fdd21..8b690ef306de 100644 --- a/drivers/gpu/drm/drm_agpsupport.c +++ b/drivers/gpu/drm/drm_agpsupport.c @@ -285,7 +285,7 @@ int drm_agp_unbind(struct drm_device *dev, struct drm_agp_binding *request) entry = drm_agp_lookup_entry(dev, request->handle); if (!entry || !entry->bound) return -EINVAL; - ret = drm_unbind_agp(entry->memory); + ret = agp_unbind_memory(entry->memory); if (ret == 0) entry->bound = 0; return ret; @@ -326,7 +326,7 @@ int drm_agp_bind(struct drm_device *dev, struct drm_agp_binding *request) if (!entry || entry->bound) return -EINVAL; page = DIV_ROUND_UP(request->offset, PAGE_SIZE); - retcode = drm_bind_agp(entry->memory, page); + retcode = agp_bind_memory(entry->memory, page); if (retcode) return retcode; entry->bound = dev->agp->base + (page << PAGE_SHIFT); @@ -369,11 +369,11 @@ int drm_agp_free(struct drm_device *dev, struct drm_agp_buffer *request) if (!entry) return -EINVAL; if (entry->bound) - drm_unbind_agp(entry->memory); + agp_unbind_memory(entry->memory);list_del(&entry->head); - drm_free_agp(entry->memory, entry->pages);+ agp_free_memory(entry->memory); kfree(entry); return 0; } @@ -453,8 +453,8 @@ void drm_legacy_agp_clear(struct drm_device *dev)list_for_each_entry_safe(entry, tempe, &dev->agp->memory, head) {if (entry->bound) - drm_unbind_agp(entry->memory); - drm_free_agp(entry->memory, entry->pages); + agp_unbind_memory(entry->memory); + agp_free_memory(entry->memory); kfree(entry); } INIT_LIST_HEAD(&dev->agp->memory); diff --git a/drivers/gpu/drm/drm_memory.c b/drivers/gpu/drm/drm_memory.c index fbea69d6f909..f4f2bffdd5bd 100644 --- a/drivers/gpu/drm/drm_memory.c +++ b/drivers/gpu/drm/drm_memory.c @@ -100,24 +100,6 @@ static void *agp_remap(unsigned long offset, unsigned long size, return addr; }-/** Wrapper around agp_free_memory() */-void drm_free_agp(struct agp_memory *handle, int pages) -{ - agp_free_memory(handle); -} - -/** Wrapper around agp_bind_memory() */ -int drm_bind_agp(struct agp_memory *handle, unsigned int start) -{ - return agp_bind_memory(handle, start); -} - -/** Wrapper around agp_unbind_memory() */ -int drm_unbind_agp(struct agp_memory *handle) -{ - return agp_unbind_memory(handle); -} - #else /* CONFIG_AGP */ static inline void *agp_remap(unsigned long offset, unsigned long size, struct drm_device *dev) diff --git a/include/drm/drm_agpsupport.h b/include/drm/drm_agpsupport.h index 664e120b93e6..f3136750c490 100644 --- a/include/drm/drm_agpsupport.h +++ b/include/drm/drm_agpsupport.h @@ -28,10 +28,6 @@ struct drm_agp_head {#if IS_ENABLED(CONFIG_AGP) -void drm_free_agp(struct agp_memory * handle, int pages);-int drm_bind_agp(struct agp_memory * handle, unsigned int start); -int drm_unbind_agp(struct agp_memory * handle); - struct drm_agp_head *drm_agp_init(struct drm_device *dev); void drm_legacy_agp_clear(struct drm_device *dev); int drm_agp_acquire(struct drm_device *dev); @@ -61,20 +57,6 @@ int drm_agp_bind_ioctl(struct drm_device *dev, void *data,#else /* CONFIG_AGP */ -static inline void drm_free_agp(struct agp_memory * handle, int pages)-{ -} - -static inline int drm_bind_agp(struct agp_memory * handle, unsigned int start) -{ - return -ENODEV; -} - -static inline int drm_unbind_agp(struct agp_memory * handle) -{ - return -ENODEV; -} - static inline struct drm_agp_head *drm_agp_init(struct drm_device *dev) { return NULL; -- 2.29.2
