From: Daniel Vetter Date: Tue, 8 Sep 2015 11:56:23 +0000 (+0200) Subject: drm/i915: Mark debug mod options as _unsafe X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25e1793f6c642604b13e33bc81a9c8d48d652c86;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Mark debug mod options as _unsafe We don't want random people to touch these. Especially true since we've just screwed up SKL by holding it way too long under the preliminary flag because of some ABI issues. And now there's howtos all over the internets about how to set this. Same pretty much for anything else.
