Direct Rendering Manager (DRM) framework with Kernel Mode Setting (KMS) became generic API for the graphics display stack for Linux. Recently introduced extensions like atomic mode setting and universal planes allows to expose most of the features of the graphics display subsystem to generic applications, which don't need to use any hardware specific API. The next common part of graphics hardware (especially in the embedded systems) are various picture processing modules (i.e. copying, colour space conversion, scaling, rotation, etc). Such blocks can be used by vendor specific extensions. However this is not the best approach, especially if one want to design some hardware-independent application. This talk will focus on presenting the new proposal for the extension to the DRM subsystem, which provides access to the picture processing hardware blocks in the unified and generic way.
