From c3e50f89006cca9c422c9b3cf83c6dd84bc91f52 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Thu, 6 Jun 2019 08:53:12 -0400 Subject: [PATCH] drm/amd/display: Set default ABM level to module parameter [Why] The module parameter to specify the default ABM level is now defined, so hook it up in DM. [How] On connector reset specify the default level. DC will program this as part of the modeset since it gets passed onto the stream in dm_update_crtc_state. It's only set for eDP connectors, but it doesn't matter if this is specified for connectors or hardware that doesn't support ABM. It's DC's responsibility to check that ABM can be set or adjusted, and DC does check that the DMCU firmware is running and if there's backlight control available.
