Subject: [PATCH 1/3] drm: drm_fourcc: Add scaling and padding factor to drm_format_info
Date: Mon, 27 Nov 2017 18:27:31 -0800 [thread overview]
Message-ID: <1511836053-9489-2-git-send-email-hyun.kwon@xilinx.com> (raw)
In-Reply-To: <1511836053-9489-1-git-send-email-hyun.kwon@xilinx.com>
From: Satish Kumar Nagireddy <satish.nagireddy.nagireddy@xilinx.com>
'cpp_scale' can be used as a multiplying factor to calculate
bytes per component based on color format.
For eg. scaling factor of YUV420 8 bit format is 1
so multiplying factor is 1 (8/8)
scaling factor of YUV420 10 bit format is 1.25 (10/8)
'padding_scale' can be used as a multiplying factor to calculate
actual width of video according to color format.
For eg. padding factor of YUV420 8 bit format: 8 bits per 1 component
no padding bits here, so multiplying factor is 1
padding factor of YUV422 10 bit format: 32 bits per 3 components
each component is 10 bit and the factor is 32/30
