Subject: [PATCH v2 1/2] drm/fourcc: add a 10bits fully packed variant of NV12
Date: Thu, 21 Jun 2018 21:42:42 +0800 [thread overview]
Message-ID: <20180621134243.9557-2-ayaka@soulik.info> (raw)
In-Reply-To: <20180621134243.9557-1-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. The color gamut
follows the BT.2020 standard.
