Subject: [PATCH v2 03/17] media: v4l2: Add Apple interchange pixel formats
Date: Sat, 26 Sep 2026 15:14:42 +0200 [thread overview]
Message-ID: <20260926-avd-v2-3-ecebe6a3648e@icloud.com> (raw)
In-Reply-To: <20260926-avd-v2-0-ecebe6a3648e@icloud.com>
Apple Interchange is a compressed and tiled format modifier.
Its intended use is for sharing buffers between hardware blocks (GPU,
display controller, video codecs) on Apple platforms.
Add it to the v4l2_format_info table to help with calculating sizes.
