Subject: [PATCH v10 2/2] drm/fourcc: add a 10bits fully packed variant of NV12
Date: Thu, 10 Jan 2019 03:57:10 +0800 [thread overview]
Message-ID: <20190109195710.28501-3-ayaka@soulik.info> (raw)
In-Reply-To: <20190109195710.28501-1-ayaka@soulik.info>
This pixel format is a fully packed and 10bits variant of NV12.
A luma pixel would take 10bits in memory, without any
filled bits between pixels in a stride.
