From 9a758d8756daab5b8fda006e131c066336b16a32 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 11 Nov 2022 14:30:23 +0100 Subject: drm: Move nomodeset kernel parameter to drivers/video Move the nomodeset kernel parameter to drivers/video to make it available to non-DRM drivers. Adapt the interface, but keep the DRM interface drm_firmware_drivers_only() to avoid churn within DRM. The function should later be inlined into callers. The parameter disables any DRM graphics driver that would replace a driver for firmware-provided scanout buffers. It is an option to easily fallback to basic graphics output if the hardware's native driver is broken. Moving it to a more prominent location wil make it available to fbdev as well. v2: * clarify the meaning of the nomodeset parameter (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221111133024.9897-2-tzimmermann@suse.de --- drivers/video/Kconfig | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/video/Kconfig') diff --git a/drivers/video/Kconfig b/drivers/video/Kconfig index 0587e21abad9..6d2fde6c5d11 100644 --- a/drivers/video/Kconfig +++ b/drivers/video/Kconfig @@ -11,6 +11,10 @@ config APERTURE_HELPERS Support tracking and hand-over of aperture ownership.
