FBDEV Drivers Will Honor "nomodeset" With Linux 6.2

Adding to the material queuing in DRM-Next is another drm-misc-next pull which is likely the last batch of DRM core and small driver feature updates expected for Linux 6.2.

With being at the Linux 6.1-rc5 stage, feature work going into DRM-Next is drawing to a close while Maxime Ripard sent in today a batch of drm-misc-next update of patches touching the DRM core code as well as the various smaller DRM/KMS drivers.

Today's drm-misc-next work isn't too notable but mostly a number of smaller DRM core changes and to the different drivers like VC4, V3D, Mediatek MTK, HiSilicon, and others. There are fixes and other minor bits not really exciting to end-users.

One item worth mentioning though and warranting this news item is that Linux 6.2 will now honor the "nomodeset" option for FBDEV drivers.

The "nomodeset" option has long been available that when passed as a Linux kernel option will prevent the hardware-specific Direct Rendering Manager drivers from loading and sticking to whatever hardware-agnostic display driver is loaded for driving the display's frame-buffer. This nomodeset option has worked well when wanting to avoid DRM/KMS drivers due to hardware issues or other problems and just wanting to get a basic display up.

With Linux 6.2, the nomodeset option will now also be honored by the FBDEV drivers so that no frame-buffer device driver will replace any hardware-agnostic driver when this option is present. Thanks to the work of Thomas Zimmermann at SUSE, the nomodeset option is basically being consistently honored by both DRM and FBDEV drivers.

The full list of drm-misc-next feature patches for the week can be found via this pull.
