Nicholas Kazlauskas 7df7e505e8 drm/amd/display: Set requested plane state DCC params for GFX9 ... [Why] Hardware support for Delta Color Compression (DCC) decompression is available in DC for GFX9 but there's no way for userspace to enable the feature. Enabling the feature can provide improved GFX performance and power savings in many situations. [How] The GFX9 DCC parameters are passed to amdgpu_dm from AMDGPU via the amdgpu_bo tiling_flags. The plane capability is queried and the parameters are set accordingly. The DCC address is given via a 256 byte aligned offset on the framebuffer address. The DCC address is updated whenever the buffer address changes.
