From: Javier Martinez Canillas Date: Fri, 17 Dec 2021 00:37:49 +0000 (+0100) Subject: drm/sti: Add support for the nomodeset kernel parameter X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=89ec0023200e20ab4f601aaae1e457a0026209bc;p=linux.git drm/sti: Add support for the nomodeset kernel parameter According to disable Documentation/admin-guide/kernel-parameters.txt, this parameter can be used to disable kernel modesetting. DRM drivers will not perform display-mode changes or accelerated rendering and only the system framebuffer will be available if it was set-up. But only a few DRM drivers currently check for nomodeset, make this driver to also support the command line parameter.
