374  * 1. All modes currently on the connector's modes list are marked as stale
376  * 2. New modes are added to the connector's probed_modes list with
377  *    drm_mode_probed_add(). New modes start their life with status as OK.
378  *    Modes are added from a single source using the following priority order.
382  *      VESA DMT modes up to 1024x768 are automatically added
385  *    Finally modes specified via the kernel command line (video=...) are
387  *    (drm_helper_probe_add_cmdline_mode()). These modes are generated
390  * 3. Modes are moved from the probed_modes list to the modes list. Potential
394  * 4. Any non-stale mode on the modes list then undergoes validation
397  *    - drm_mode_validate_size() filters out modes larger than @maxX and @maxY
399  *    - drm_mode_validate_flag() checks the modes against basic connector
409  * 5. Any mode whose status is not OK is pruned from the connector's modes list,
414  * The number of modes found on @connector.
