Possible typo:

This latest batch includes more work around the WattMan-like functionality for fine-grainted clock

This is still pretty unstable for GCN 1.0 users. I had to switch back to Radeon since I've had so many problems with AMDGPU. Cinnamon would freeze randomly, while games in RetroArch would run extremely slowly. A Hat In Time which btw only works in Wine Stating 3.3, will take a few minutes to start up, where it it usually instant in Radeon.

I like Vulkan and it works well with AMDGPU on GCN 1.0, but the RadeonSI driver is buggy.

Fine grained clock adjustment? As no need to flash the bios each time I want to update my card OC? That will be great, especially if they dont put limit because my rx480 like to have the gpu voltage to 1.33v

Does Wattman support, include undervolting support ? Today with amdgpu v17.50 on linux 4.13 apparently don't transmit lower voltage from the bios itself...

For us with vega this is a must as bios flashing is a bit of a meh project.
