From 09a4ec5da92c84952db117f0d576fdd8368c873a Mon Sep 17 00:00:00 2001 From: Dillon Varone Date: Fri, 17 Nov 2023 16:37:50 -0500 Subject: drm/amd/display: Refactor dc_state interface [WHY?] Part of the dc_state interface that deals with adding streams and planes should remain public, while others that deal with internal status' and subvp should be private to DC. [HOW?] Move and rename the public functions to dc_state.h and private functions to dc_state_priv.h. Also add some additional functions for extracting subvp meta data from the state.
