Detailed Description

Gdk::DmabufTextureBuilder is a builder used to construct Gdk::Texture objects from DMA buffers.

DMA buffers are commonly called dma-bufs.

DMA buffers is a feature of the Linux kernel to enable efficient buffer and memory sharing between hardware such as codecs, GPUs, displays, cameras and the kernel drivers controlling them. For example, a decoder may want its output to be directly shared with the display server for rendering without a copy.

Any device driver which participates in DMA buffer sharing, can do so as either the exporter or importer of buffers (or both).

The memory that is shared via DMA buffers is usually stored in non-system memory (maybe in device's local memory or something else not directly accessible by the CPU), and accessing this memory from the CPU may have higher than usual overhead.

In particular for graphics data, it is not uncommon that data consists of multiple separate blocks of memory, for example one block for each of the red, green and blue channels. These blocks are called planes. DMA buffers can have up to four planes. Even if the memory is a single block, the data can be organized in multiple planes, by specifying offsets from the beginning of the data.

DMA buffers are exposed to user-space as file descriptors allowing to pass them between processes. If a DMA buffer has multiple planes, there is one file descriptor per plane.

The format of the data (for graphics data, essentially its colorspace) is described by a 32-bit integer. These format identifiers are defined in the header file drm/drm_fourcc.h and commonly referred to as fourcc values, since they are identified by 4 ASCII characters. Additionally, each DMA buffer has a modifier, which is a 64-bit integer that describes driver-specific details of the memory layout, such as tiling or compression.

The operation of Gdk::DmabufTextureBuilder is quite simple: Create a texture builder, set all the necessary properties, and then call build() to create the new texture.

The required properties for a dma-buf texture are

The width and height in pixels
The fourcc code and modifier which identify the format and memory layout of the dma-buf
The file descriptor, offset and stride for each of the planes

Gdk::DmabufTextureBuilder can be used for quick one-shot construction of textures as well as kept around and reused to construct multiple textures.

Member Function Documentation

◆ build()

Glib::RefPtr< Texture > Gdk::DmabufTextureBuilder::build ( const SlotDmabufTextureReleased & slot = {} )

Builds a new Gdk::Texture with the values set up in the builder.

It is a programming error to call this function if any mandatory property has not been set.

If the dmabuf is not supported by GTK, an exception will be thrown.

The slot gets called when the returned texture gets released.

It is possible to call this function multiple times to create multiple textures, possibly with changing properties in between.

It is the responsibility of the caller to keep the file descriptors for the planes open until the created texture is no longer used, and close them afterwards (possibly using the slot notify).

Not all formats defined in the drm_fourcc.h header are supported. You can use Gdk::Display::get_dmabuf_formats() to get a list of supported formats.

Since gtkmm 4.14:

Parameters

slot	Destroy function to be called when the texture is released.

Returns: A newly built Gdk::Texture or an empty RefPtr if the format is not supported, or any mandatory property has not been set.

Together with property_update_texture() this describes an update of a previous texture.

When rendering animations of large textures, it is possible that consecutive textures are only updating contents in parts of the texture. It is then possible to describe this update via these two properties, so that GTK can avoid rerendering parts that did not change.

An example would be a screen recording where only the mouse pointer moves.

Parameters

texture The texture to update.
