| From | Javier Martinez Canillas <> | Subject | [PATCH 04/60] drm/armada: Add support for the nomodeset kernel parameter | Date | Wed, 15 Dec 2021 01:59:12 +0100 |
| |
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 systewm 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.
