dma-buf: add new dma_fence_chain container v7 Lockless container implementation similar to a dma_fence_array, but with only two elements per node and automatic garbage collection. v2: properly document dma_fence_chain_for_each, add dma_fence_chain_find_seqno, drop prev reference during garbage collection if it's not a chain fence. v3: use head and iterator for dma_fence_chain_for_each v4: fix reference count in dma_fence_chain_enable_signaling v5: fix iteration when walking each chain node v6: add __rcu for member 'prev' of struct chain node v7: fix rcu warnings from kernel robot Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Link: https://patchwork.freedesktop.org/patch/295778/?series=58813&rev=1

dma-buf: Add dma-buf heaps framework This framework allows a unified userspace interface for dma-buf exporters, allowing userland to allocate specific types of memory for use in dma-buf sharing. Each heap is given its own device node, which a user can allocate a dma-buf fd from using the DMA_HEAP_IOC_ALLOC. This code is an evoluiton of the Android ION implementation, and a big thanks is due to its authors/maintainers over time for their effort: Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard, Laura Abbott, and many other contributors!

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

dma-buf: Introduce selftesting framework In light of recent review slip ups, the absence of a suite of tests for dma-buf became apparent. Given the current plethora of testing frameworks, opt for one already in use by Intel's CI and so allow easy hook up into igt. We introduce a new module that when loaded will execute the list of selftests and their subtest. The names of the selftests are put into the modinfo as parameters so that igt can identify each, and run them independently, principally for ease of error reporting.
