Use the DRM interface to h/w accelerate composition on image surfaces. The purpose of the backend is simply to explore what such a hardware interface might look like and what benefits we might expect. The use case that might justify writing such custom backends are embedded devices running a drm compositor like wayland - which would, for example, allow one to write applications that seamlessly integrated accelerated, dynamic, high quality 2D graphics using Cairo with advanced interaction (e.g. smooth animations in the UI) driven by a clutter framework... In this first step we introduce the fundamental wrapping of GEM for intel and radeon chipsets, and, for comparison, gallium. No acceleration, all we do is use buffer objects (that is use the kernel memory manager) to allocate images and simply use the fallback mechanism. This provides a suitable base to start writing chip specific drivers. |

This directory provides code that is common to both of cairo's tests suites: * The test suite for correctness in test/ * The test suite for performance in perf/ We call it boilerplate as it consists primarily of the boilerplate code necessary for initializing a backend in order to create a surface for that backend. The code here just might be useful for someone looking to get started writing cairo code to use a particular backend, (but there are no promises that the boilerplate code found here for any particular backend is exemplary).
