The docs say possible_clones should always include the encoder itself. Since most drivers don't want to deal with the complexities of cloning let's allow them to set possible_clones=0 and instead we'll fix that up in the core. We can't put this special case into drm_encoder_init() because drivers will have to fill up possible_clones after adding all the relevant encoders. Otherwise they wouldn't know the proper encoder indexes to use. So we'll just do it just before registering the device. v2: Don't set the bit if possible_clones!=0 so that the validation (coming soon) will WARN (Thomas) Fix up the docs to allow possible_clones==0 (Daniel) .late_register() is too late, introduce drm_mode_config_validate() which gets called _before_ we register the char device (Daniel) Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200211162208.16224-2-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> |

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
