From 26e0842439bfd826a2b9dca80f9b9a57bbb0a690 Mon Sep 17 00:00:00 2001 From: Abdiel Janulgue Date: Mon, 27 Mar 2017 12:48:48 +0300 Subject: tests/kms_hdmi_inject: Add test for HDMI injection capabilities. Original author: Marius Vlad. Includes fixes below. v5: Convert unit tests to lib selftest. v4: Add a unit test to make sure synthetic EDID blocks generated by IGT is valid (suggested by Petri). v3: Make audio injection work.
