Subject: [PATCH 08/21] drm/amd/display: Fix IGT link training failure on Replay panel
Date: Wed, 28 Jan 2026 09:51:33 +0800 [thread overview]
Message-ID: <20260128015538.568712-9-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20260128015538.568712-1-Wayne.Lin@amd.com>
From: Ray Wu <ray.wu@amd.com>
[Why]
IGT link-training-configs test fails to set the link rate on Replay panels
because some link rate types are not supported in debugfs. As a result,
debugfs treats these link rates as invalid, causing the IGT test to fail.
[How]
Add missing link rate types to resolve this issue.
