From: Kieran Bingham <kieran.bingham@xxxxxxxxxxxxxxxx> Our kms-tests test suite for verifying the R-Car DU is based on kmsxx. We are implementing a 'loop-back' validator, by providing an HDMI cable from the display output directly into the HDMI receiver on the same development board. By using the existing VideoStreamer and pyvid objects, we can capture the output and compare to provide automated display validation. As an effort to commence this process, this series implements a basic frame buffer comparison, which expects identical frame sizes to operate. This could be could be expanded upon later to provide a more detailed comparison at the pixel level later, but this serves as an initial starting point to quickly verify if the data captured matches the data that we expected.
