Optimizing graphics memory bandwidth with compression and tiling: Notes on DRM format modifiers

Until recently, the FourCC format code of a buffer provided a nearly comprehensive description of its contents. But as hardware design has advanced, placing the buffers in a non-traditional (nonlinear) fashion has become more important in order to gain performance. A given buffer layout can prove to be more suited for particular use-cases than others, such as tiled formats to improve locality of access and enable fast local buffering.
