Subject: [PATCH 04/19] drm/amd/display: Unset Replay desync error verification by default
Date: Wed, 15 Apr 2026 15:39:43 +0800 [thread overview]
Message-ID: <20260415074223.34848-5-chen-yu.chen@amd.com> (raw)
In-Reply-To: <20260415074223.34848-1-chen-yu.chen@amd.com>
From: Allen Li <Allen.Li@amd.com>
[Why & How]
There will be an unexpected desync error while doing PSR -> Replay transit,
so we want to disable the replay desync error detection by default.
