Hi AMD graphics developers, I've recently hit a modesetting problem: when I used the DisplayPort KVM switch that I got yesterday to connect my PC (running Arch Linux) to my 4K monitor, it only worked in 3 out of about 60 times of switching/replugging the cable (the BIOS always manages to put something onscreen, though). I've tried both graphics cards available to me right now: a Polaris (RX 480) and a Cayman (HD 6950/6970) and neither of them modesets properly and reliably. I wouldn't be opposed to doing some work to fix this myself, as this is a good opportunity for me to get into system development, however I don't know where to start. I have full (root if required) access to the system, so building/running custom kernels or whatever is necessary is not a big problem. However, logic analysers (or whatever you may need to find out what actually goes over the wire) are out of my reach. Is this something I can tackle?
Yours faithfully Jona Stubbe PS: if there is a shorter-latency way of asking this kind of question (like an IRC channel), I'd be interested too :)
