Subject: [PATCH 0/4] fbdev: Internalize fbcon
Date: Wed, 20 May 2026 18:00:35 +0200	[thread overview]
Message-ID: <20260520160744.130841-1-tzimmermann@suse.de> (raw)

Turn fbcon into an internal client of fbdev. Manage all interactions
with graphics drivers within fbdev. Add helpers for these tasks and
convert drivers.

Fbdev's PS3 and SH-Mobile drivers update fbcon as part of user-invoked
mode changes. Call the new helpers, which also fix inconsistencies
among the various code paths.

Vga-switcheroo remaps the fbcon terminals when switching physical
outputs. For now, hide this in another helper. The call will later
move into DRM's fbdev emulation.

When all refactoring in place, fbdev manages fbcon interactions by
itself. Remove the public interfaces.

Thomas Zimmermann (4):
  fbdev: Wrap user-invoked calls to fb_set_var() in helper
  fbdev: Wrap user-invoked calls to fb_blank() in helper
  fbdev: Wrap fbcon updates from vga-switcheroo in helper
  fbdev: Do not export fbcon from fbdev
