Subject: [PATCH 06/12] drm/format-helper: Rework XRGB8888-to-RGB888 conversion
Date: Wed, 27 Jul 2022 13:33:06 +0200 [thread overview]
Message-ID: <20220727113312.22407-7-tzimmermann@suse.de> (raw)
In-Reply-To: <20220727113312.22407-1-tzimmermann@suse.de>
Update XRGB8888-to-RGB888 conversion to support struct iosys_map
and convert all users. Although these are single-plane color formats,
the new interface supports multi-plane formats for consistency with
drm_fb_blit().
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
