Subject: [PATCH libdrm 2/3] modetest: Add support for YUV422 and YUV444
Date: Sat, 7 Jul 2018 19:35:32 -0700	[thread overview]
Message-ID: <1531017333-1483-3-git-send-email-hyun.kwon@xilinx.com> (raw)
In-Reply-To: <1531017333-1483-1-git-send-email-hyun.kwon@xilinx.com>

This allows dumb buffer allocation for YUV422 and YUV444 with correct
subsampling values.
