Phoronix: AMD Working On New OverDrive GPU Overclocking Controls For Linux

AMD's open-source Linux graphics driver engineers are working on a new set of interfaces for user-space to support OverDrive overclocking. While AMD GPU OverDrive overclocking has been supported on Linux for years, the current interface isn't sufficient for all the power/overclocking controls moving forward...

These new interfaces are just for SMU13 / RDNA3 and newer with prior GPU hardware not allowing such controls.

I'm running an RDNA2 as well and it's a little sad they are already abandoning it, especially when RDNA3 is just an incremental update and not a fundamentally new architecture.

Similar architecture, however, very dissimilar behaviour due to chiplet design in RDNA3. I suspect a majority of their developers are now on RDNA5 as RDNA4 is presumably close to finished. My guess is the monolithic chip nature of RDNA4 mid-range SKUs will be similar to RDNA2 and we might see an update then..

RDNA2 already supports this functionality. This was added to enable some level of manual fan control on RDNA3 which is already possible on RDNA2.

Thanks AMD, that's what I needed for 7900xtx.

their focus is on rdna5. they actually shelved a lot of rdna 4 projects and its now going to be a small upgrade. its going to be similar to how polaris was. they had way to many problems getting the chiplets to work right and rdna5 is solving that vast bulk of it. so all focus has been switched onto it. at least according to moores law is dead podcast.

It's not, it simply doesn't have the new OverDrive interfaces introduced in RDNA3

Would love to see some support for CPU overclocking and (more interesting to me) undervolting under Linux as well. The GPU stuff is cool and all, but for CPU there really isn't much.

This stuff isn't all that useful or intuitive if there is no GUI to manage it all. Nvidia, despite it's shortcomings still has a better configuration GUI and more useful options provided on Linux. AMD is doing the bare minimum here when it comes to their software support.
