[PATCH v2 30/37] drm/omap: Add support for the nomodeset kernel parameter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
