For the purpose of testing things such as hotplugging and bad monitors, the ChromeOS team ended up designing a neat little device known as the Chamelium. More information on this can be found here: https://www.chromium.org/chromium-os/testing/chamelium This adds support for a couple of things to intel-gpu-tools: - igt library functions for connecting to udev and monitoring it for hotplug events, loosely based off of the unfinished hotplugging implementation in testdisplay - Library functions for controlling the chamelium in tests using xmlrpc. A couple of RPC calls were ommitted here, mainly because they didn't seem very useful for our needs or because they're just plain broken - A set of basic tests using the chamelium. Because there's no surefire way that I know of where we can map which chamelium port belongs to which port on the system being tested (we could just use hotplugging, but then we'd be relying on something that might be broken on the machine and potentially give false positives for certain tests), most of the chamelium tests will figure out whether or not a connection happened by counting the number of connectors matching the status we're looking for before hotplugging with the chamelium, vs. after hotplugging it. Tests which require that we know which port belongs to a certain port (such as ones where we actually perform a modeset) will unplug all of the chamelium ports, plug the desired port, then use the first DRM connector with the desired connector type that's marked as connected. In order to ensure we don't end up using the wrong connector, these tests will skip if they find any connectors with the desired type marked as connected before performing the hotplug on the chamelium. Running these tests requires (of course) a working Chamelium, along with the RPC URL for the chamelium being specified in the environment variable CHAMELIUM_HOST. If no URL is specified, the tests will just skip on their own. As well, tests for connectors which are not actually present on the system or the chamelium will skip on their own as well.
