New userspace API is focused ONLY on memory-to-memory image processing. The two remainging IPP operation modes (framebuffer writeback and local-path output with image processing) can be implemented using standard DRM features: writeback connectors and additional DRM planes with scaling features. V2 IPP userspace API is not compatible with old IPP ioctls. This is a significant change, but the old IPP subsystem in mainline Linux kernel was partially disfunctional anyway and not used in any open-source project. V2 IPP userspace API is based on stateless approach, which much better fits to memory-to-memory image processing model. It also provides support for all image formats, which are both already defined in DRM API and supported by the existing IPP hardware modules. The API consists of the following ioctls: - DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image processing modules, - DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image formats of given IPP module, - DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for selected image format of given IPP module, - DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the provided structures (source and destination buffers, operation rectangle, transformation, etc). The proposed userspace API is extensible. In the future more advanced image processing operations can be defined to support for example blending. Userspace API is fully functional also on DRM render nodes, so it is not limited to the root/privileged client. Internal driver API also has been completely rewritten. New IPP core performs all possible input validation, checks and object life-time control. The drivers can focus only on writing configuration to hardware registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies the driver API. Minimal driver needs to provide a single callback for starting processing and an array with supported image formats.
