Immediately after a client binds to this interface, - the set of supported formats is sent with 'format' 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 - zlinux_dmabuf_params object with zlinux_dmabuf.create_params - request. All planes required by the intended format are added with - the 'add' request. Finally, 'create' request is issued. The server - will reply with either 'created' event which provides the final - wl_buffer or 'failed' event saying that it cannot use the dmabufs - provided. - - - - - Objects created through this interface, especially wl_buffers, will - remain valid. - - - - - - This temporary object is used to collect multiple dmabuf handles into - a single batch to create a wl_buffer. It can only be used once and - should be destroyed after an 'created' or 'failed' event has been - received. - - - - - - - This event advertises one buffer format that the server supports. - All the supported formats are advertised once when the client - binds to this interface. A roundtrip after binding guarantees, - that the client has received all supported formats. - - For the definition of the format codes, see create request. - - XXX: Can a compositor ever enumerate them? - - - - - - - - - This temporary object is a collection of dmabufs and other - parameters that together form a single logical buffer. The temporary - object may eventually create one wl_buffer unless cancelled by - destroying it before requesting 'create'. - - Single-planar formats only require one dmabuf, however - multi-planar formats may require more than one dmabuf. For all - formats, 'add' request must be called once per plane (even if the - underlying dmabuf fd is identical). - - You must use consecutive plane indices ('plane_idx' argument for 'add') - from zero to the number of planes used by the drm_fourcc format code. - All planes required by the format must be given exactly once, but can - be given in any order. Each plane index can be set only once. - - - - - - - - - - - - - - - - - - - - - Cleans up the temporary data sent to the server for dmabuf-based - wl_buffer creation. - - - - - - This request adds one dmabuf to the set in this zlinux_buffer_params. - - The 64-bit unsigned value combined from modifier_hi and modifier_lo - is the dmabuf layout modifier. DRM AddFB2 ioctl calls this the - fb modifier, which is defined in drm_mode.h of Linux UAPI. - This is an opaque token. Drivers use this token to express tiling, - compression, etc. driver-specific modifications to the base format - defined by the DRM fourcc code. - - This request raises the PLANE_IDX error if plane_idx is too large. - The error PLANE_SET is raised if attempting to set a plane that - was already set. - - - - - - - - - - - - - - - - - - - This asks for creation of a wl_buffer from the added dmabuf - buffers. The wl_buffer is not created immediately but returned via - the 'created' event if the dmabuf sharing succeeds. The sharing - may fail at runtime for reasons a client cannot predict, in - which case the 'failed' event is triggered. - - 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 - ordering between the two fields is top field first, unless - 'bottom_first' is specified. It is undefined whether 'bottom_first' - is ignored if 'interlaced' is not set. - - This protocol does not convey any information about field rate, - duration, or timing, other than the relative ordering between the - two fields in one buffer. A compositor may have to estimate the - intended field rate from the incoming buffer rate. It is undefined - whether the time of receiving wl_surface.commit with a new buffer - 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 - to just reject all interlaced buffers. - - Any argument errors, including non-positive width or height, - mismatch between the number of planes and the format, bad - format, bad offset or stride, may be indicated by fatal protocol - errors: INCOMPLETE, INVALID_FORMAT, INVALID_DIMENSIONS, - OUT_OF_BOUNDS. - - Dmabuf import errors in the server that are not obvious client - bugs are returned via the 'failed' event as non-fatal. This - allows attempting dmabuf sharing and falling back in the client - if it fails. - - This request can be sent only once in the object's lifetime, after - which the only legal request is destroy. This object should be - destroyed after issuing 'create' request. Attempting to use this - object after issuing 'create' raises ALREADY_USED protocol error. - - It is not mandatory to issue 'create'. If a client wants to - cancel the buffer creation, it can just destroy this object. - - - - - - - - - - This event indicates that the attempted buffer creation was - successful. It provides the new wl_buffer referencing the dmabuf(s). - - Upon receiving this event, the client should destroy the - zlinux_dmabuf_params object. - - - - - - - This event indicates that the attempted buffer creation has - failed.
