Immediately after a client binds to this interface,\nthe set of supported formats and format modifiers is sent with\n'format' and 'modifier' events.\n\nThe following are required from clients:\n\n- Clients must ensure that either all data in the dma-buf is\ncoherent for all subsequent read access or that coherency is\ncorrectly handled by the underlying kernel-side dma-buf\nimplementation.\n\n- Don't make any more attachments after sending the buffer to the\ncompositor. Making more attachments later increases the risk of\nthe compositor not being able to use (re-import) an existing\ndmabuf-based wl_buffer.\n\nThe underlying graphics stack must ensure the following:\n\n- The dmabuf file descriptors relayed to the server will stay valid\nfor the whole lifetime of the wl_buffer. This means the server may\nat any time use those fds to import the dmabuf into any kernel\nsub-system that might accept it.\n\nTo create a wl_buffer from one or more dmabufs, a client creates a\nzwp_linux_dmabuf_params_v1 object with a zwp_linux_dmabuf_v1.create_params\nrequest. All planes required by the intended format are added with\nthe 'add' request. Finally, a 'create' or 'create_immed' request is\nissued, which has the following outcome depending on the import success.\n\nThe 'create' request,\n- on success, triggers a 'created' event which provides the final\nwl_buffer to the client.\n- on failure, triggers a 'failed' event to convey that the server\ncannot use the dmabufs received from the client.\n\nFor the 'create_immed' request,\n- on success, the server immediately imports the added dmabufs to\ncreate a wl_buffer. No event is sent from the server in this case.\n- on failure, the server can choose to either:\n- terminate the client by raising a fatal error.\n- mark the wl_buffer as failed, and send a 'failed' event to the\nclient. If the client uses a failed wl_buffer as an argument to any\nrequest, the behaviour is compositor implementation-defined.\n\nWarning! The protocol described in this file is experimental and\nbackward incompatible changes may be made. Backward compatible changes\nmay be added together with the corresponding interface version bump.\nBackward incompatible changes are done by bumping the version number in\nthe protocol and interface names and resetting the interface version.\nOnce the protocol is to be declared stable, the 'z' prefix and the\nversion number in the protocol and interface names are removed and the\ninterface version number is reset." ] pub mod zwp_linux_dmabuf_v1 { use std :: os :: raw :: c_char ; use super :: { Proxy , AnonymousObject , Interface , MessageGroup , MessageDesc , ArgumentType , Object , Message , Argument , ObjectMetadata , types_null , NULLPTR , Main , smallvec , } ; use super :: sys :: common :: { wl_interface , wl_array , wl_argument , wl_message } ; use super :: sys :: client :: * ; pub enum Request { # [ doc = "unbind the factory\n\nObjects created through this interface, especially wl_buffers, will\nremain valid.\n\nThis is a destructor, once sent this object cannot be used any longer." ] Destroy , # [ doc = "create a temporary object for buffer parameters\n\nThis temporary object is used to collect multiple dmabuf handles into\na single batch to create a wl_buffer.

The wl_buffer is not created immediately but returned via\nthe 'created' event if the dmabuf sharing succeeds. The sharing\nmay fail at runtime for reasons a client cannot predict, in\nwhich case the 'failed' event is triggered.\n\nThe 'format' argument is a DRM_FORMAT code, as defined by the\nlibdrm's drm_fourcc.h. The Linux kernel's DRM sub-system is the\nauthoritative source on how the format codes should work.\n\nThe 'flags' is a bitfield of the flags defined in enum \"flags\".\n'y_invert' means the that the image needs to be y-flipped.\n\nFlag 'interlaced' means that the frame in the buffer is not\nprogressive as usual, but interlaced. An interlaced buffer as\nsupported here must always contain both top and bottom fields.\nThe top field always begins on the first pixel row. The temporal\nordering between the two fields is top field first, unless\n'bottom_first' is specified. It is undefined whether 'bottom_first'\nis ignored if 'interlaced' is not set.\n\nThis protocol does not convey any information about field rate,\nduration, or timing, other than the relative ordering between the\ntwo fields in one buffer. A compositor may have to estimate the\nintended field rate from the incoming buffer rate. It is undefined\nwhether the time of receiving wl_surface.commit with a new buffer\nattached, applying the wl_surface state, wl_surface.frame callback\ntrigger, presentation, or any other point in the compositor cycle\nis used to measure the frame or field times. There is no support\nfor detecting missed or late frames/fields/buffers either, and\nthere is no support whatsoever for cooperating with interlaced\ncompositor output.\n\nThe composited image quality resulting from the use of interlaced\nbuffers is explicitly undefined. A compositor may use elaborate\nhardware features or software to deinterlace and create progressive\noutput frames from a sequence of interlaced input buffers, or it\nmay produce substandard image quality. However, compositors that\ncannot guarantee reasonable image quality in all cases are recommended\nto just reject all interlaced buffers.\n\nAny argument errors, including non-positive width or height,\nmismatch between the number of planes and the format, bad\nformat, bad offset or stride, may be indicated by fatal protocol\nerrors: INCOMPLETE, INVALID_FORMAT, INVALID_DIMENSIONS,\nOUT_OF_BOUNDS.\n\nDmabuf import errors in the server that are not obvious client\nbugs are returned via the 'failed' event as non-fatal.
