From 8cf32fe06c8f54bca11c485ccc1cc3899f9d81db Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 20 Jul 2017 18:13:36 +0300 Subject: lib/igt_frame: Add support for analog frame comparison testing This adds support for analog frame comparison check, as used in VGA. Since VGA uses a DAC-ADC chain, its data cannot be expected to be pixel perfect. Thus, it is impossible to uses a CRC check and full frames have to be analyzed instead. Such an analysis is implemented, based on both an absolute error threshold and a correlation with the expected error trend for a DAC-ADC chain. It was tested with a couple encoders and provides reliable error detection with few false positives.
