dma-buf: Rename struct fence to dma_fence 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 2016-10-25 20:00:45 +08:00			`obj-y := dma-buf.o dma-fence.o dma-fence-array.o reservation.o seqno-fence.o`
dma-buf/sync_file: de-stage sync_file sync_file is useful to connect one or more fences to the file. The file is used by userspace to track fences between drivers that share DMA bufs.

dma-buf/sw_sync: de-stage SW_SYNC SW_SYNC allows to run tests on the sync_file framework via debugfs on <debugfs>/sync/sw_sync Opening and closing the file triggers creation and release of a sync timeline. To create fences on this timeline the SW_SYNC_IOC_CREATE_FENCE ioctl should be used. To increment the timeline value use SW_SYNC_IOC_INC. Also it exports Sync information on <debugfs>/sync/info Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2016-08-11 23:26:44 +08:00			`obj-$(CONFIG_SW_SYNC) += sw_sync.o sync_debug.o`
Add udmabuf misc device A driver to let userspace turn memfd regions into dma-bufs. Use case: Allows qemu create dmabufs for the vga framebuffer or virtio-gpu ressources. Then they can be passed around to display those guest things on the host. To spice client for classic full framebuffer display, and hopefully some day to wayland server for seamless guest window display. qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf Cc: David Airlie <airlied@linux.ie> Cc: Tomeu Vizoso <tomeu.vizoso@collabora.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20180827093444.23623-1-kraxel@redhat.com 2018-08-27 17:34:44 +08:00			`obj-$(CONFIG_UDMABUF) += udmabuf.o`
