From 177b76a8d8e9a41ea3f9ab163e60ed28ac8e9fd1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Tue, 7 Jan 2025 15:33:47 +0100 Subject: [PATCH] drm/amdgpu: mark a bunch of module parameters unsafe MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We sometimes have people trying to use debugging options in production environments. Mark options only meant to be used for debugging as unsafe so that the kernel is tainted when they are used.
