Description

Color is a visual perception. Human eyes can detect a broader range of colors than any devices in the graphics chain. Since each device can generate, capture or reproduce a specific subset of colors and tones, color management controls color conversion and calibration across devices to ensure a more accurate and consistent color representation. We can expose a GPU-accelerated display color management pipeline to support this process and enhance results, but color capabilities differ between HW versions and GPU vendors.

DRM/KMS API for advanced color management has been an ongoing discussion in the community for a few years, and we are now in a new stage with the generic color management proposal [1] from April-2023 Display Hackfest [2]. Therefore, this workshop is a follow-up of last year's HDR KMS API workshop [3] and Display Hackfest discussions and also the status update of all work done by the DRI community so far to provide a solution that covers the needs of all parties involved.
