From d1ebfdd8d0fc30ff65b85a4bf3fa9e5e35006466 Mon Sep 17 00:00:00 2001 From: Wyatt Wood Date: Tue, 31 Mar 2020 09:31:16 -0400 Subject: drm/amd/display: Unify psr feature flags [Why] As it stands, psr has feature flags in dm, stream, and link. Most are not defined well enough, and different dm layers have different uses for these same flags. [How] We define a new structure called psr_settings in dc_link that will hold the following psr feature flags: psr_feature_enable - psr is supported psr_allow_active - psr is currently active psr_version - internal psr version supported psr_frame_capture_indication_req psr_sdp_transmit_line_num_deadline The last two flags were moved out of the power module for the purposes of consolidating psr flags. Their use is already well-defined. Psr caps reported by sink will also be stored in dc_link, in dpcd_caps.psr_caps.
