From 7f4ce7b50ae45fd09796e98c56c8471af70322dc Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 5 Sep 2023 14:26:00 -0500 Subject: [PATCH] drm/amd: Enable seamless boot by default on newer ASICs Seamless boot can technically be supported as far back as DCN1 but to avoid regressions on older hardware, enable it for DCN3 and later. If users report using the module parameter that it works on older ASICs as well, this can be adjusted.
