From bb47de736661887f37b5380f68a3faedf077aed0 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Thu, 4 Oct 2018 13:03:30 -0400 Subject: drm/amdgpu: Set FreeSync state using drm VRR properties Support for AMDGPU specific FreeSync properties and ioctls are dropped from amdgpu_dm in favor of supporting drm variable refresh rate properties. The notify_freesync and set_freesync_property functions are dropped from amdgpu_display_funcs. The drm vrr_capable property is now attached to any DP/HDMI connector. Its value is updated accordingly to the connector's FreeSync capabiltiy. The freesync_enable logic and ioctl control has has been dropped in favor of utilizing the vrr_enabled on the drm CRTC. This allows for more fine grained atomic control over which CRTCs should support variable refresh rate. To handle state changes for vrr_enabled it was easiest to drop the forced modeset on freesync_enabled change. This patch now performs the required stream updates when planes are flipped. This is done for a few reasons: (1) VRR stream updates can be done in the fast update path (2) amdgpu_dm_atomic_check would need to be hacked apart to check desired variable refresh state and capability before the CRTC disable pass. (3) Performing VRR stream updates on-flip is needed for enabling BTR support. VRR packets and timing adjustments are now tracked and compared to previous values sent to the hardware.
