+ * @page page_iface_zwp_linux_dmabuf_v1 zwp_linux_dmabuf_v1
+ * @section page_iface_zwp_linux_dmabuf_v1_desc Description
+ *
+ * Following the interfaces from:
+ * https://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_image_dma_buf_import.txt
+ * and the Linux DRM sub-system's AddFb2 ioctl.
+ *
+ * This interface offers ways to create generic dmabuf-based
+ * wl_buffers. Immediately after a client binds to this interface,
+ * the set of supported formats and format modifiers is sent with
+ * 'format' and 'modifier' events.
+ *
+ * The following are required from clients:
+ *
+ * - Clients must ensure that either all data in the dma-buf is
+ * coherent for all subsequent read access or that coherency is
+ * correctly handled by the underlying kernel-side dma-buf
+ * implementation.
+ *
+ * - Don't make any more attachments after sending the buffer to the
+ * compositor. Making more attachments later increases the risk of
+ * the compositor not being able to use (re-import) an existing
+ * dmabuf-based wl_buffer.
+ *
+ * The underlying graphics stack must ensure the following:
+ *
+ * - The dmabuf file descriptors relayed to the server will stay valid
+ * for the whole lifetime of the wl_buffer. This means the server may
+ * at any time use those fds to import the dmabuf into any kernel
+ * sub-system that might accept it.
+ *
+ * To create a wl_buffer from one or more dmabufs, a client creates a
+ * zwp_linux_dmabuf_params_v1 object with a zwp_linux_dmabuf_v1.create_params
+ * request. All planes required by the intended format are added with
+ * the 'add' request. Finally, a 'create' or 'create_immed' request is
+ * issued, which has the following outcome depending on the import success.
+ *
+ * The 'create' request,
+ * - on success, triggers a 'created' event which provides the final
+ * wl_buffer to the client.
+ * - on failure, triggers a 'failed' event to convey that the server
+ * cannot use the dmabufs received from the client.
+ *
+ * For the 'create_immed' request,
+ * - on success, the server immediately imports the added dmabufs to
+ * create a wl_buffer. No event is sent from the server in this case.
+ * - on failure, the server can choose to either:
+ * - terminate the client by raising a fatal error.
+ * - mark the wl_buffer as failed, and send a 'failed' event to the
+ * client. If the client uses a failed wl_buffer as an argument to any
+ * request, the behaviour is compositor implementation-defined.
+ *
+ * Warning! The protocol described in this file is experimental and
+ * backward incompatible changes may be made. Backward compatible changes
+ * may be added together with the corresponding interface version bump.
+ * Backward incompatible changes are done by bumping the version number in
+ * the protocol and interface names and resetting the interface version.
+ * Once the protocol is to be declared stable, the 'z' prefix and the

+ * @defgroup iface_zwp_linux_dmabuf_v1 The zwp_linux_dmabuf_v1 interface
+ *
+ * Following the interfaces from:
+ * https://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_image_dma_buf_import.txt
+ * and the Linux DRM sub-system's AddFb2 ioctl.
+ *
+ * This interface offers ways to create generic dmabuf-based
+ * wl_buffers. Immediately after a client binds to this interface,
+ * the set of supported formats and format modifiers is sent with
+ * 'format' and 'modifier' events.
+ *
+ * The following are required from clients:
+ *
+ * - Clients must ensure that either all data in the dma-buf is
+ * coherent for all subsequent read access or that coherency is
+ * correctly handled by the underlying kernel-side dma-buf
+ * implementation.
+ *
+ * - Don't make any more attachments after sending the buffer to the
+ * compositor. Making more attachments later increases the risk of
+ * the compositor not being able to use (re-import) an existing
+ * dmabuf-based wl_buffer.
+ *
+ * The underlying graphics stack must ensure the following:
+ *
+ * - The dmabuf file descriptors relayed to the server will stay valid
+ * for the whole lifetime of the wl_buffer. This means the server may
+ * at any time use those fds to import the dmabuf into any kernel
+ * sub-system that might accept it.
+ *
+ * To create a wl_buffer from one or more dmabufs, a client creates a
+ * zwp_linux_dmabuf_params_v1 object with a zwp_linux_dmabuf_v1.create_params
+ * request. All planes required by the intended format are added with
+ * the 'add' request. Finally, a 'create' or 'create_immed' request is
+ * issued, which has the following outcome depending on the import success.
+ *
+ * The 'create' request,
+ * - on success, triggers a 'created' event which provides the final
+ * wl_buffer to the client.
+ * - on failure, triggers a 'failed' event to convey that the server
+ * cannot use the dmabufs received from the client.
+ *
+ * For the 'create_immed' request,
+ * - on success, the server immediately imports the added dmabufs to
+ * create a wl_buffer. No event is sent from the server in this case.
+ * - on failure, the server can choose to either:
+ * - terminate the client by raising a fatal error.
+ * - mark the wl_buffer as failed, and send a 'failed' event to the
+ * client. If the client uses a failed wl_buffer as an argument to any
+ * request, the behaviour is compositor implementation-defined.
+ *
+ * Warning! The protocol described in this file is experimental and
+ * backward incompatible changes may be made. Backward compatible changes
+ * may be added together with the corresponding interface version bump.
+ * Backward incompatible changes are done by bumping the version number in
+ * the protocol and interface names and resetting the interface version.
+ * Once the protocol is to be declared stable, the 'z' prefix and the
+ * version number in the protocol and interface names are removed and the
+ * interface version number is reset.

+ * The 'format' argument is a DRM_FORMAT code, as defined by the
+ * libdrm's drm_fourcc.h. The Linux kernel's DRM sub-system is the
+ * authoritative source on how the format codes should work.
+ *
+ * The 'flags' is a bitfield of the flags defined in enum "flags".
+ * 'y_invert' means the that the image needs to be y-flipped.
+ *
+ * Flag 'interlaced' means that the frame in the buffer is not
+ * progressive as usual, but interlaced. An interlaced buffer as
+ * supported here must always contain both top and bottom fields.
+ * The top field always begins on the first pixel row. The temporal

+ * attached, applying the wl_surface state, wl_surface.frame callback
+ * trigger, presentation, or any other point in the compositor cycle
+ * is used to measure the frame or field times. There is no support
+ * for detecting missed or late frames/fields/buffers either, and
+ * there is no support whatsoever for cooperating with interlaced
+ * compositor output.
+ *
+ * The composited image quality resulting from the use of interlaced
+ * buffers is explicitly undefined. A compositor may use elaborate
+ * hardware features or software to deinterlace and create progressive
+ * output frames from a sequence of interlaced input buffers, or it
+ * may produce substandard image quality. However, compositors that
+ * cannot guarantee reasonable image quality in all cases are recommended

+ * if it fails.
