What does this mean for DP MST support for existing cards? I have a R9 380 and I'm currently using the fglrx driver (patched to support newer kernels) because the AMDGPU driver does not seem to support this feature yet in anything other than mirrored mode for the monitors connected to the DP MST hub, unless I'm doing it wrong somehow. With fglrx it "just works" and sees all of the monitors in amdcccle. Harry's DAL post on dri-devel in February indicated that DAL would allow support for up to six displays in any configuration, including DP MST. Will we have to wait until DAL/DC is mainlined for this to be supported or is it something that will be supported before then in some form? I'm not sure if AMDGPU-PRO supports this yet since I don't use Ubuntu or RHEL.
Thank you to AMD for supporting open source drivers.
