linux-toradex.git/drivers/gpu/drm/amd/include, branch master Linux kernel for Apalis and Colibri modules drm/amd/display: Disable FRL and add module param to enable it 2026-06-03T17:45:01+00:00 Fangzhi Zuo Jerry.Zuo@amd.com 2026-05-13T21:02:03+00:00 c3778921bf0d582b8d22457834a10e98e0bf9eab FRL links don't yet support VRR. If we enable it by default users will see a functional regression when connected to an FRL capable display as the driver will now default to FRL and not allow VRR. VRR support will come soon, so instead of making an elaborate TMDS fallback mechanism simply default FRL to disabled, but provide a dcfeaturemask of 0x400 to enable it if anyone wants to already try it out.

FRL links don't yet support VRR. If we enable it by default
users will see a functional regression when connected to an FRL
capable display as the driver will now default to FRL and not
allow VRR.

VRR support will come soon, so instead of making an elaborate
TMDS fallback mechanism simply default FRL to disabled, but
provide a dcfeaturemask of 0x400 to enable it if anyone wants
to already try it out.
