2024-07-22drm/nouveau: use GEM references instead of TTMsDanilo Krummrich
TTM wants to get rid of the duplicate refcounting of the embedded GEM object and its own reference count. Hence, use of GEM object references where possible. Also get rid of nouveau_bo_ref() and replace it with nouveau_bo_fini(), which drops the initial reference we get from initializing a ttm_bo.

2021-06-02drm/ttm: rename bo->mem and make it a pointerChristian König
When we want to decouble resource management from buffer management we need to be able to handle resources separately. Add a resource pointer and rename bo->mem so that all code needs to change to access the pointer instead. No functional change.

2020-12-14drm/ttm: cleanup BO size handling v3Christian König
Based on an idea from Dave, but cleaned up a bit. We had multiple fields for essentially the same thing. Now bo->base.size is the original size of the BO in arbitrary units, usually bytes. bo->mem.num_pages is the size in number of pages in the resource domain of bo->mem.mem_type. v2: use the GEM object size instead of the BO size v3: fix printks in some places Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> (v1) Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/406831/

2016-10-25dma-buf: Rename struct fence to dma_fenceChris Wilson
I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing! (v2...: rebase, rerun spatch) v3: Compile on msm, spotted a manual fixup that I broke. v4: Try again for msm, sorry Daniel coccinelle script: @@ @@ - struct fence + struct dma_fence @@ @@ - struct fence_ops + struct dma_fence_ops @@ @@ - struct fence_cb + struct dma_fence_cb @@ @@ - struct fence_array + struct dma_fence_array @@ @@ - enum fence_flag_bits + enum dma_fence_flag_bits @@ @@ ( - fence_init + dma_fence_init | - fence_release + dma_fence_release | - fence_free + dma_fence_free | - fence_get + dma_fence_get | - fence_get_rcu + dma_fence_get_rcu | - fence_put + dma_fence_put | - fence_signal + dma_fence_signal | - fence_signal_locked + dma_fence_signal_locked | - fence_default_wait + dma_fence_default_wait | - fence_add_callback + dma_fence_add_callback | - fence_remove_callback + dma_fence_remove_callback | - fence_enable_sw_signaling + dma_fence_enable_sw_signaling | - fence_is_signaled_locked + dma_fence_is_signaled_locked | - fence_is_signaled + dma_fence_is_signaled | - fence_is_later + dma_fence_is_later | - fence_later + dma_fence_later | - fence_wait_timeout + dma_fence_wait_timeout | - fence_wait_any_timeout + dma_fence_wait_any_timeout | - fence_wait + dma_fence_wait | - fence_context_alloc + dma_fence_context_alloc | - fence_array_create + dma_fence_array_create | - to_fence_array + to_dma_fence_array | - fence_is_array + dma_fence_is_array | - trace_fence_emit + trace_dma_fence_emit | - FENCE_TRACE + DMA_FENCE_TRACE | - FENCE_WARN + DMA_FENCE_WARN | - FENCE_ERR + DMA_FENCE_ERR ) ( ... ) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Acked-by: Sumit Semwal <sumit.semwal@linaro.org> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161025120045.28839-1-chris@chris-wilson.co.uk

2015-08-28drm/nouveau/nvif: simplify and tidy library interfacesBen Skeggs
A variety of tweaks to the NVIF library interfaces, mostly ripping out things that turned out to be not so useful. - Removed refcounting from nvif_object, callers are expected to not be stupid instead. - nvif_client is directly reachable from anything derived from nvif_object, removing the need for heuristics to locate it - _new() versions of interfaces, that allocate memory for the object they construct, have been removed. The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

2014-12-02drm/nouveau: teach nouveau_bo_pin() how to force a contig vram allocationBen Skeggs
We have the ability to move buffers around in the kernel if necessary, and should probably use it rather than failing if userspace passes us a non-contig buffer for a plane. The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere initial placement hint once all the relevant paths have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
