Subject: [PATCH LIBDRM 2/3] modetest: Add support for YUV422 and YUV444
Date: Fri, 4 May 2018 16:40:53 -0700 [thread overview]
Message-ID: <1525477254-3338-3-git-send-email-hyun.kwon@xilinx.com> (raw)
In-Reply-To: <1525477254-3338-1-git-send-email-hyun.kwon@xilinx.com>
This allows dumb buffer allocation for YUV422 and YUV444 with correct
subsampling values.
