    Subject[PATCH 11/60] drm/gud: Add support for the nomodeset kernel parameter
    Date
    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.
