VEGA 20 (Aka Vega12)

[Rodrigo Luglio]

I have a macbook pro with vega 20 which uses the amdgpu firmware vega12 and when i boot any distro the graphics glitch and the computer freezes. If i install amdgpu pro on ubuntu it works flawlessly. Would you guys help me debug this and fix for upstream? 


Please, let me know which kind of logs and information I can attach in order to start debugging this issue. I’ll be more than happy to be part of it!
