[PATCH v3 00/10] drm: Make drivers to honour the nomodeset parameter
Hi patches 6 to 10 are Acked-by: Thomas Zimmermann <tzimmermann at suse.de> Best regards Thomas Am 22.12.21 um 09:28 schrieb Javier Martinez Canillas:> The nomodeset kernel command line parameter is used to prevent the KMS/DRM > drivers to be registered/probed.
