From c67e62790f5c156705fb162da840c6d89d0af6e0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Thu, 8 Oct 2020 12:57:32 +0200 Subject: drm/prime: split array import functions v4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mapping the imported pages of a DMA-buf into an userspace process doesn't work as expected. But we have reoccurring requests on this approach, so split the functions for this and document that dma_buf_mmap() needs to be used instead. v2: split it into two functions v3: rebased on latest changes v4: update commit message a bit Signed-off-by: Christian König Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/403838/ --- drivers/gpu/drm/omapdrm/omap_gem.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/gpu/drm/omapdrm/omap_gem.c') diff --git a/drivers/gpu/drm/omapdrm/omap_gem.c b/drivers/gpu/drm/omapdrm/omap_gem.c index 30d299ca8795..38af6195d959 100644 --- a/drivers/gpu/drm/omapdrm/omap_gem.c +++ b/drivers/gpu/drm/omapdrm/omap_gem.c @@ -1324,8 +1324,7 @@ struct drm_gem_object *omap_gem_new_dmabuf(struct drm_device *dev, size_t size, } omap_obj->pages = pages; - ret = drm_prime_sg_to_page_addr_arrays(sgt, pages, NULL, - npages); + ret = drm_prime_sg_to_page_array(sgt, pages, npages); if (ret) { omap_gem_free_object(obj); obj = ERR_PTR(-ENOMEM); -- cgit v1.2.3
