Subject: [PATCH v2 0/3] arch: Remove fbdev dependency from video helpers
Date: Wed, 27 Mar 2024 21:41:28 +0100 [thread overview]
Message-ID: <20240327204450.14914-1-tzimmermann@suse.de> (raw)
Make architecture helpers for display functionality depend on general
video functionality instead of fbdev. This avoids the dependency on
fbdev and makes the functionality available for non-fbdev code.
Patch 1 replaces the variety of Kconfig options that control the
Makefiles with CONFIG_VIDEO. More fine-grained control of the build
can then be done within each video/ directory; see parisc for an
example.
Patch 2 replaces fb_is_primary_device() with video_is_primary_device(),
which has no dependencies on fbdev. The implementation remains identical
on all affected platforms. There's one minor change in fbcon, which is
the only caller of fb_is_primary_device().
Patch 3 renames the source and files from fbdev to video.
v2:
- improve cover letter
- rebase onto v6.9-rc1
Thomas Zimmermann (3):
arch: Select fbdev helpers with CONFIG_VIDEO
arch: Remove struct fb_info from video helpers
arch: Rename fbdev header and source files
