I don't think that was ever an issue. It's more that some teams built a bunch of infrastructure that used libdrm tests and haven't had the resources to switch to IGT yet. Alex

Why can't amd run the igt tests? Afaiui on the display side this is happening already, at least sometimes. And yes regression tests matter, it just feels silly that we need to have them 2x for amdgpu.
